discuss the energy transformation taking place in the following cases -
a) a working electric geyser
b)a glowing electric bulb
c)a working electric fan
d)burning cooking gas
e)a bullet fired from a gun
f)working engine of moving motor car
g)a swinging pendulum
h)a catapult just releasing a stone
(a) Electrical energy into heat energy [Heating effect of current]
(b) Electrical energy into heat energy which in turns converted into light energy.
(c) Electrical energy into mechanical energy
(d) Chemical energy into heat energy
(e) Mechanical energy stored in the spring is converted into kinetic energy
(f) Chemical energy of the fuel is converted into heat energy [burning of fuel]
Heat energy is converted into mechanical energy [Rotor movement of wheels]
(g) Potential energy is converted into Kinetic energy and vice versa
(h) Energy stored due to the elasticity of the catapult is converted into kinetic energy.
(b) Electrical energy into heat energy which in turns converted into light energy.
