What sacrifices have you made in life?
I sacrificed a lot of associations just because I preferred to stay indoor an read. I know it kept me a lot of shits but it also denied me chance to grow in business. I feel bad about it because what I worked soo hard to get is being treated to be made obsolete by the AI. I have spent fortune time on books
All latitudes except the equator are small circles. The path joining two points on the same latitude forms an arc of the circle of that latitude.
The radius r of a latitude is given by r=R cos θ where θ is the angle of latitude.
Along the small circle defined by θoN or θoS, an arc of length 60 cos θ nm subtends an angle of 1o at the center of that latitude. That is;
1o = 60 cos θ nm on a latitude θoN or θoS. Also note that 1 nm = 1.853 km.
Consider two positions on the surface of the earth illustrated below.
The distance AB will be given by AB = (x/360)o x 2𝝅r= (x/360)o x 2𝝅R Cos θ .
that is; r = Rcosθ
θ is the angle of latitude and x is the value of angle difference between the longitude of the two points A and B.
Find the distance between the following pair of points in km given that 𝝅 = 22/7 and R = 6370 km.
(a) R(70oS, 35oW), S(70oS, 80oE)
(b) R(14oN, 100oE), S(14oN, 10oE)
What’s the oldest things you’re wearing today?
My pullover mum bought for me many 13 years ago. It is a pullover I love dearly, nothing much has changed about it except some fading and few holes around the arm sleeves. It is a white silk pullover with shiny pink threads interwoven so that I look like a shining star from a distance. I have bought many clothes that I have dumped then but this one, no, because I always feel that a great love brought it to me
Are you a leader or a follower?
We are always influenced by other people around us, so we we are followed by default. As a leader you are always in pursuit of knowledge, we read books, magazines and go through social medias to get ideas about our trade. And so we follow others no matter our status in society. Even the president follows his subjects to know their feelings and opinions.
We are also leaders in our own rights if we influence one another to make this or that decision, whatever the capacity we do it.
List your top 5 favorite fruits.
A banana is an elongated, edible fruit – botanically a berry – produced by several kinds of large herbaceous flowering plants in the genus Musa. A banana is an elongated, edible fruit – botanically a berry – produced by several kinds of large herbaceous flowering plants in the genus Musa.
Bananas are healthy, delicious, and versatile fruits. They’re full of nutrients that could help prevent constipation, improve digestive and gut health, and promote recovery from intense activity. Eating one banana per day will provide: 12% of the DV for vitamin C.
The pineapple (Ananas comosus) is a tropical plant with an edible fruit; it is the most economically significant plant in the family Bromeliaceae.
Pineapple contains nutrients and beneficial compounds, such as vitamin C, manganese, and enzymes, to help aid digestion. Eating pineapple may help boost immunity, lower cancer risk, and improve recovery time after surgery.
An orange is the fruit of a tree in the family Rutaceae that originated in a region encompassing Southern China, Northeast India, and Myanmar;
Botanically, this is the hybrid Citrus × sinensis, between the pomelo (Citrus maxima) and the mandarin orange (Citrus reticulata). The chloroplast genome, and therefore the maternal line, is that of pomelo.
The sweet orange has had its full genome sequenced.
oranges has other health benefits includes:
formally known as Cucumis metuliferus but informally also goes by horned melonand African horned cucumber, Thorn melon is an exotic and richly nutritious fruit from Africa that offers many health benefits.
Thorn melon has a significant number of antioxidants that guard against diabetes, heart disease, cancer, and many other disorders.
Tomato is the edible berry of the plant Solanum lycopersicum, commonly known as the tomato plant that originated in western South America, Mexico and Central America.
Tomatoes are juicy and sweet, full of antioxidants, and may help fight several diseases. They are especially high in lycopene, a plant compound linked to improved heart health, cancer prevention, and protection against sunburns. Tomatoes can be a valuable part of a healthy diet.
Electromagnetic waves are usually detected by devices or gadgets. The human eye can only detect only a small portion of this spectrum called visible light. A radio detects a different portion of the spectrum, and an x-ray machine uses yet another portion.
Detected by photographic plates and radiation detectors like Geiger Muller Tubes.
we need a gamma spectrometer to know the energy ranges of the γ photons emitted by a radioactive source. A gamma spectrometer generally consists of a scintillation detector or a semiconductor detector to convert the γ rays into visible light or electronic signals respectively. With a multi-channel analyser, a gamma spectrum depicting the number distribution of γ photons at different energy ranges can be obtained. The γ spectrum is like the “fingerprints” of nuclides which facilitate the identification of different nuclides in a radioactive source.
By counting the rate of charge pulses or voltage pulses or measuring the scintillation of the light emitted, the number and energy of gamma ray photon striking an ionisation detector or scintillation counter can be found.
In X-ray detectors the energy transported by the radiation is converted into forms that can be recognized visually or electronically. Generally the photons are absorbed by the detector material and energy transfer takes place by ionization.
X-rays are usually detected by using a fluorescent screen or photographic film.
In hospitals, X-rays used to observe broken bones are detected by their actions on specially designed photographic emulsions. This high energy radiation may also be detected by its ability to ionise gas atoms producing a pulse of electric current in a gas placed between two electrodes.
Geiger Muller counter using the ionisation of gas atoms detects the presence of both X-rays and gamma rays.
It is usually detected by photographic films, photocells, fluorescent materials like quinine and sulphate and a paper slightly smeared with vaseline.
Quinine, a substance found in tonic water is sensitive to UV light and can absorb UV light that we can’t see and then re-emit visible blue light that we can see in a process known as fluorescence
A fluorescent material is one that absorbs the energy of UltraViolet light and then re-emits it as visible light.
The inner surface of a fluorescent tube is coated with a fluorescent material .The tube is filled with a gas that emits UV light when made to conduct by a high voltage.
Common detectors of visible light are the eye, photographic film, charge-coupled devices (CCDs) and the photocell.
Photographic films detects light by the chemical changes it produces in light-sensitive chemicals such as silver halides. Light is also detected by the photoelectric effect in which its energy causes electrons to be emitted from metal surfaces.
By use of photoelectric effect, electrons are collected in a photomultiplier tube and the current they produce amplified to produce an electric signal.
Semiconductors are used to produce photovoltaic cells which generate a current when light falls on them and photoresistors in which incident light causes a change in electrical resistance.
It is usually detected by the heating effect produced on the skin, a thermopile, bolometer and thermometer with a blackened bulb.
A bolometer contains a blackened metal strip whose temperature rises when infrared radiations falls on it and this temperature is detected by measuring the change in electrical resistance of the strip.
When infrared radiation falls on semiconductor surface, it may produce an electromotive force(e.m.f) which decreases the electrical resistance of the material.
Photographic films sensitive to infrared radiations can be used to take infrared pictures that reveals hotspots in the landscape.
Microwaves are detected by crystal detectors or solid state diodes. The energy of these wave bands is absorbed by conduction electrons in metals causing electrons to vibrate in the same frequencies as the waves.
Radio waves are detected by aerials or antennae. The energy of radio wave bands is absorbed by the conduction electrons in metals causing the electrons to vibrate at the same frequencies as the waves. The resulting alternating current can be amplified electronically to produce an electrical signals with the same pattern as the radio waves. For maximum sensitivity, the size of the antennae should be of the same order as the wavelength of the radio waves.
What’s one small improvement you can make in your life?
Spend less time on tasks by avoiding distraction, Exercise more, and rest more.
I have technically lost ability to rest an so resting has become an important skill to have and difficult to acquire.
Now improving myself would in involve ability to stay doing nothing for like one hour without touching my gadgets and wanting to watch a tv screen.
Share a story about someone who had a positive impact on your life.
In the vast tapestry of human experiences, few bonds are as profound and enduring as that between a mother and her child. It is a relationship marked by sacrifice, resilience, and unconditional love, transcending the boundaries of circumstance and adversity. Such is the story of countless mothers around the world, whose unwavering dedication shapes the destinies of their children in remarkable ways.
One such narrative unfolds in the life of Cyrus, whose journey from humble beginnings to academic achievement is a testament to the transformative power of a mother’s love. Raised in the midst of poverty, I experienced firsthand the challenges of making ends meet, yet amidst the hardships, there stood a beacon of hope and strength: his mother.
From the earliest days of childhood my mum exemplified the essence of resilience. Despite the meager resources at her disposal, she poured her heart and soul into ensuring her children’s well-being. Whether it was braving long journeys to fetch water, laboring in the fields to put food on the table, or selling vegetables in the market, she spared no effort to provide for her family’s needs.
One poignant memory etched in mind is the instance when i fell ill with pneumonia at the tender age of twelve. Unable to afford transportation, mum carried me on her back for ten kilometers to seek medical attention. It was a journey marked by her unwavering determination and love, a testament to the lengths she would go to protect and care for her child.
Despite the hardships we faced mum never wavered in her belief in the power of education. She instilled in me the value of learning, sacrificing her own comfort to ensure i had access to schooling. Through her guidance and encouragement,i not only completed my education but excelled, eventually attaining a college degree—a feat made possible by mother’s unwavering support and belief in my potential.
Beyond the realm of material provision, mum imparted invaluable lessons in morality and spirituality. Despite our impoverished circumstances, she nurtured a strong sense of faith and integrity, teaching us the ways of God and instilling within us a deep reverence for moral values. Her steadfast devotion to attending church every Sunday served as a guiding light, illuminating the path towards a life rooted in righteousness and compassion.
Yet, amidst the virtues she imparted, i acknowledges inheriting one aspect of mum’s character that posed a challenge: emotional anger. However, rather than succumbing to its negative influence,i have helped her overcome it through giving her experiences of peaceful circumstances i have encountered with God. Through patience, understanding, and mutual love, we have forged a bond that transcended our flaws, emerging stronger and more resilient than before.
In reflecting on his journey, am filled with gratitude for the profound impact my mum has had on my life. Her unwavering love, resilience, and unwavering faith have shaped me into the person am today, instilling within me the values of compassion, perseverance, and gratitude. As i continues to navigate life’s challenges, i carries with me the enduring legacy of a mother’s love—a force that knows no bounds and transcends the limitations of circumstance.
It is a testament to the resilience of the human spirit, the strength of familial bonds, and the enduring legacy of selfless sacrifice. As we celebrate the myriad contributions of mothers everywhere, let us not forget the profound impact they have on shaping the destinies of generations to come—a legacy of love that knows no bounds.
What does freedom mean to you?
I value freedom. Colonized nations fought for freedom and citizens in democratic nations pride themselves in some kind of freedom.
But you can have freedom but still not free. You can have freedom to do one thing but lack it in something else.
When we say we are free, are we free indeed.?
Types of freedom includes
This is when we have enough money so that nothing that requires money that we can be restricted from. It is freedom to have whatever we desire because we can be can afford it. You may not be in prison walls but you are life is soo restricted because of being broke or poor. You cannot move even though you have freedom to move whenever you many want because you lack resources to do that. Financial freedom keeps people from attaining their desires just like people locked behind bars crave for freedom. I remember in my days of small beginnings how I desired to join some schools and get education but all I could have are desires, I could just watch the institutions walls from a distance but could not go there because I was poor. I was a prisoner of desires I could never attain just the way prisoners look at people with freedom of movement but cannot go anywhere because they are locked.
Other types of freedom includes:
This is a privilege enjoyed by citizens of democratic societies or nations where they can express their thoughts and opinions without being judged harshly
This is where we are not restricted in movement and we can travel or go where we need to go . But I think physical freedom is connected to financial freedom because without money you can only be able to go to only limited places.
It is when you have peace in your soul and you are not haunted by things like guilt, anxiety or tormented by things beyond your control
Ability to think clearly and have clarity of thoughts. It is where you have power to imagine and have the means to test your thoughts.
Ability to express your political views without intimidation , coercion or persuasion.
Protection from undue influence or pressure from academic institutions, governments, or external organizations that may seek to limit or control academic inquiry and expression.
However If you have financial freedom, you can be able to purchase physical freedom as well ,,,so I think …….🤔
The electromagnetic (EM) spectrum is the range of all types of Electromagnetic radiation. Radiation is energy that travels and spreads out as it goes – the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation.
Electromagnetic waves are transverse waves which results from oscillating electric and magnetic fields at right angles to each other.
When all the electromagnetic spectrum are arranged in order of their wavelength or frequency, they form what is refered to as the electromagnetic spectrum.
A complete spectrum is shown below:
The figure below shows electromagnetic waves arranged in order of decreasing wavelengths
Electromagnetic waves have the following common properties.
A certain electromagnetic radiation was found to be having a wavelength of 6.5 x 10-8 m. Calculate the energy it emits.
to calculate energy of a wave, you need to know about it’s frequency and then multiply the frequency with the planck’s constant.
we have only the wavelength only but we can get the frequency from the relation: v = fλ
since it is an electromagnetic wave, it’s speed is 3.0 x 10-8 ms-1. and hence f=v/λ. that is:
=4.6154 x 1015 HZ
The energy of a wave was defined as E = hf where h (plank’s constant)= 6.63×10−34 Js
hence E = 6.63 x 10-34 Js x 4.6154 x 1015 HZ≈ 3.06 x 10-20J
