If the mass of the spacecraft were doubled, how much would the force of gravity would change?

The law of conservation of energy is a statement that : energy must be conserved and you are breaking a law if you waste energy. the total amount of energy is constant for a closed system. the supply of energy is limited so we must conserve.

Which best describes the energy of a sound wave as it travels through a medium? It increases. It decreases. It remains the same. It depends on the medium.

The masses of blocks A and B in the figure (Figure 1) are 20.0 kg and 10.0 kg, respectively. The blocks are initially at rest on the floor and are connected by a massless string passing over a massless and frictionless pulley.
