when you drop a pebble from height h, it reaches the ground with kinetic energy k if there is no air resistance. from what height

From the initial height h

Explanation:

When a material or substance is drop from a height h, it possesses potential energy, immediately it is dropped from that height, the potential energy is gradually converted to kinetic energy, it gets to a point where the potential energy equals the kinetic energy, as the material touches the ground, all potential energy has been converted to kinetic energy already

Answer : The speed of waves along the wire is, 1.2 m/s

Explanation :

Formula used :

where,

= frequency =

= wavelength =

c = speed of wave = ?

Now put all the given value in the above formula, we get the speed of waves along the wire.

Thus, the speed of waves along the wire is, 1.2 m/s
