Calculate the heat energy needed to change the temperature of 2 kg of copper from 10°c to 110°c. heat = kcal

Amplitude is a measure of a waves a; speed b; distance c; energy d; frequency

If the speed of a particle triples ,by what factor does its kinetic energy increase?

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?
