If in the space i.e an ideal condition where there is no gravity, a ball is hit with some force and the ball accelerates, so does its kinetic energy also increase constantly with the increase in velocity?
Where does that energy come from?
How can we calculate the work done?

I will be thankful to you all for ur answers.

Does anyone here try IQ tests, which are freely available on the web? I myself find the test interesting. However, the test score can make you happy or depressed.

So I was wondering how accurate the IQ tests are in reality.

I saw this on a tv program a few years ago and I was wondering if anyone has ever seen a website with a model of it. It looks like a bunch of spiral orbits around the earth.

I almost finished medical school, but when i was suddenly diagnosed with diabetes and discovered that i have chronic hypertension. i discovered that i can't handle the stress, my blood pressure will shoot up even with medications, when i was on duty and on call, there are times that i don't eat or can't eat right away due to the volume of patients coming in, patients come first, that's why. I would have migraines and feel that i'm on the verge of a nervous breakdown. lack of sleep would also aggravate my diabetes and hypertension. I feel that i was killing myself, little by little, what's worse, is that i began questioning if all of these were worth it, since it will put my health in serious jeopardy. I was not feeling well for most of the time, so I suddenly lost interest with what i was doing, the drive and determination were lost. So that's when i decided to quit and have a change of lifestyle. I want to live longer, so i put my health first

COMMUNICATION CIRCUIT DESIGN AND IMPLEMENTATION.
Hello there, good people.. I'm studying Elex and Telecom at a coll affiliated to the Univ. of Pune, but unfortunately, the practical aspects of commn ckt design are not a part of the syllabus here. I want to design a very basic AM transceiver (just coz I'd love to design 1) I want to be able to design RF circuits, the way I'm able to design digital ckts. Now, can you suggest me a good place to start? A book, perhaps? And btw, how do you know so much about practical RF design? Was it a part of your syllabus at the BE level? Reply. Thank you!

A veterinarian has 500 feet of fencing suitable for making animal runs. He wants to use it all to fence in a rectangular area with three interior fences running from end to end of the rectangular area so that four parallel rectangular runs are made for his larger animals. If he builds so that the overall area is maximized, what will be the length of one of the interior fences?

With all other factors held constant (such as light frequency, water temperature, air temperature, nutrient supply), the photosynthetic growth, I, in grams per day, for a certain plant, hydroponically grown in artificial light, depends on the light intensity, x, measured in kilowatts, according to the formula I(x) = 180x^2 - 90x^3 . What value of x (correct to two decimal places) maximizes the photosynthetic growth?

A severely ill patient is given an intramuscular injection of a highly potent antibiotic agent. It is known that the blood concentration, C, measured in micrograms per cc of the agent, increases according to the formula C = 2t/(t^2 + 9), where t is measured in hours after the time of injection. Correct to the nearest tenth of an hour, when will the concentration be maximal?
