Check the correctness of given equation
s = ut + (1/2)at^2

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

wavelength divides in half and speed stays the same.

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.
