Which statement describes a characteristic
common to all electromagnetic waves and
mechanical waves?
(1) both types of waves travel at the same speed.
(2) both types of waves require a material medium
for propagation.
(3) both types of waves propagate in a vacuum.
(4) both types of waves transfer energy.

The correct answer is (4).

Explanation:

Electromagnetic wave is the transverse wave. It is produced by the moving charged particle. It travels at the speed of the light. It does not require a medium to travel. It can travel through the vacuum.

In mechanical wave, there is an oscillation of matter. It requires a medium to travel. It cannot travel through vacuum. The three types of mechanical waves are longitudinal wave, transverse wave and surface wave.

The common characteristics to all electromagnetic waves and mechanical waves are both can move through matter and both can occur as a result of a disturbance. This disturbance is a result of wave transfer energy.

Therefore, the common characteristic to all electromagnetic and mechanical waves is both types of waves transfer energy.  

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

pls mark as brainliest.

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop
