What does the term terminal velocity mean?

Terminal velocity is the constant speed (in a particular direction) a body reaches when the forces are balanced , i.e. acceleration = 0 m s -2 . An example of this is a ball bearing dropped in oil. ⬆ Resista...

A hair dryer uses 2000J in 5 seconds when on full power. The power used is?

we are told that E = 2000J and t = 5s we need to find P recall which formula used energy, time and power P = E/t sub in values P = 2000/5 = 400 W (DONT FORGET UNITS)
