Name all 4.

Answer : a power supply of a circuit that was horizontal of the ladder where they controlled the circuit

spectral lines lyman is one set

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.
