Ball A is dropped from the top of a building of height h at the same instant that ball B is thrown vertically upward from the ground. When the balls collide, they are moving in opposite directions, and the speed of A is 5 times that of B.

Which list gives the proper sequence of energy changes that occur in a hydroelectric plant? The mechanical energy of the turbine rotates the generator parts The turbine blades capture the kinetic energy of the water Electrical energy is transferred

A locomotive is pulling 16 freight cars, each of which is loaded with the same amount of weight. The mass of each freight car (with its load) is 37,000 kg. If the train is accelerating at 0.

What is the special feature of the upper mantle?

What is the difference between weight and mass? mass and weight are both intrinsic properties of an object. if you multiply the mass of an object by the acceleration due to gravity, you will obtain the object's weight.
