Consider the masses shown. if u=0.25, find: a) the acceleration of the entire system
b) the tension of the rope between the blocks

electromagnetic waves travel through space with vacuums. give me brainliest if right.

moving ball hits still ball. mover stops, hit ball moves. momentum transfer.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
