Momentum of a system is only conserved when

Edward tolman explained the results of his study by theorizing that the rats were learning about the maze during every trial but they a. were agitated because other groups were getting reinforcement b. could not remember how to demonstrate it without reinforcement c. were not motivated to demonstrate it without reinforcement d. seemed to be too lazy to actually work without reinforcement

Because light travels in a straight line and casts a shadow, isaac newton hypothesized that light is

The law of the conservation of momentum says that the total momentum of any closed and isolated system cannot
