A cell containing cyanamide is least likely to carry on the process of what transport

A2 kg ball travellng to the right with a speed of 4 m/s collidees with a 5 kg ball traveling to the left with a speed of 3 m/s. take right to be the positive direction. what is the total momentum of the two balls before they collide? what is the total momentum of the two balls after they collide?

To do work, this truck uses energy stored in chemical fuel and an electrical battery. how much total energy does this truck put out?

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.
