Water flows over a section of niagara falls at a rate of 6.00 ´ 105 kg/s and falls 50.0 m. what is the power dissipated by the waterfall?

The answer is: PE lost every second = mgh = 1.2x10^6 * 9.81 * 50 = 5.89x10^8J So, Power = 5.89x10^8W

By dividing you can find the answer

Texture and composition are different because they are not the same aspect. texture has to do with feel and so on, where as composition is the chemical makeup which you cant touch like you can texture.
