8. Door bell converts electrical energy into
energy​

Answer 1

Answer:

(1) kinetic energy is directly propotional to the square of velocity as the mass of any body is constant

(2) when the body is at some height it acquires potential energy as per formula U=mgh

(3)solar cell works from distance because of excess of frequency of sunlight can damage the solar cell

(5)animal and plants depend mainly on sunlight because sunlight is the key part of ecosystem as:

sunlight----->producers---------->consumer ( animal)

(6)wind is the renewable source of energy.

(7) washing machine converts electric energy into mechanical energy

(8)Doorbell converts electric energy into sound energy
