What does constant acceleration look like on a graph? Constant acceleration means a horizontal line for the acceleration graph. Constant acceleration = constant slope = straight line for the velocity graph. The area under the acceleration graph is the change in velocity. How do you find velocity with time and position? Given an equation that […]

What do u mean by Q factor? quality factor Is high Q factor good? A higher Q results in a higher peak, but this must be narrower than what a lower Q device has to have the same total integral.) A high Q factor is good in resonators and watches, where operation at a single […]

Is Fusion more powerful than fission? Fusion releases more energy than fission reaction. so that we can say that fusion is more powerful than fission. Why fusion is impossible on Earth? Normally, fusion is not possible because the strongly repulsive electrostatic forces between the positively charged nuclei prevent them from getting close enough together to […]

How do I tune my C to low E? Start by plucking your low E string. Tune it down two whole steps to C by turning the tuning peg towards you. Keep plucking the string until you reach the correct note. Generally, it’s better to go a little flat of the note you’re targeting, then […]

How many joules of heat are needed to raise the temperature of 5.0 grams of 22 C to 32 C if the specific heat of aluminum is 0.90 JGC? 45 J What is the CP and CV? The Cp/Cv ratio is also called the heat capacity ratio. In thermodynamics, the heat capacity ratio is known […]

When an electron jumps from higher energy orbit to lower energy orbit the difference in the energies in the two orbits is radiated as quantum photon of? Solution. When an electron jumps from a higher energy orbit to a lower energy orbit, the difference in the energies in the two orbits is radiated as quantum […]

Why is it warmer in the winter and cooler in the summer if you live beside a large body of water compared to the temperatures inland? Large bodies of water such as oceans, seas, and large lakes affect the climate of an area. Water heats and cools more slowly than land. Therefore, in the summer, […]

What is a change in momentum? 1) The change in momentum of an object is its mass times the change in its velocity. 2) The change in the momentum of an object can also be found by considering the force acting on it. If a force, F , acts on an object for a time, […]

How long can I drive with a bad rack and pinion? It is definitely not safe to drive with a bad rack and pinion because you no longer can control your vehicle and keep it in a straight line. There would be so much free play and your vehicle would just wander on the road. […]

How long is piece string? Phrase. How long is a piece of string? (colloquial, often humorous, rhetorical question) Used as a response to a question such as “How long will it take?” or “How big is it?” when the length or size is unknown, infinite, variable, or relative. Is a piece of string infinite? But […]
