Where does the energy go when a ball bounces? When a bouncing ball falls, it initially gains speed or kinetic energy—the energy of motion. When it reaches Earth, it collides head-on with an incredibly massive object that is, from your perspective, at rest. The ball slows down, deforms temporarily and shoots back up. At what […]
Why Nitrogen is not a greenhouse gas?
Why Nitrogen is not a greenhouse gas? Oxygen and nitrogen are not greenhouse gases, because they are transparent to infrared light. These molecules are invisible because when you stretch one, it doesn’t change the electric field. In general, symmetrical molecules with only two atoms are not greenhouse gases. Why is sulfur dioxide not a greenhouse […]
Why weight is measured in kg not in Newton?
Why weight is measured in kg not in Newton? Yes. When we use kilograms to measure weight, we are actually referring to kgf or kilogram-force. From Wikipedia: One kilogram-force is equal to the magnitude of the force exerted by one kilogram of mass in a 9.80665 m/s2 gravitational field. In other words, the weight(force) of […]
What is the common ratio for this geometric sequence 4 24 144?
What is the common ratio for this geometric sequence 4 24 144? = 6 (answer). What is the formula of common difference? The common difference is the value between each number in an arithmetic sequence. Therefore, you can say that the formula to find the common difference of an arithmetic sequence is: d = a(n) […]
Which branch of science is the most important?
Which branch of science is the most important? I used to think that chemistry was most important, because all matter is made up of atoms and this determines the properties of every material, and the chemical reactions that are responsible for all of life. (And if you forced me to give a simple answer, I’d […]

How do you know if you have vas deferens?
How do you know if you have vas deferens? Structure. There are two vasa deferentia, connecting the left and right epididymis with the seminal vesicles to form the ejaculatory duct in order to move sperm. In humans, each tube is about 30 centimeters (1 ft) long, 3 to 5 mm (0.118 to 0.197 inches) in […]
Which engine gives more efficiency?
Which engine gives more efficiency? Diesel engines Why did old V8s make so little power? Why do large-displacement American V8s generally produce less horsepower per liter of displacement compared to their European and Japanese counterparts? A common answer is that American engines are tuned to favor low-end torque instead of top-end horsepower, but that answer […]
