Conversion of mass from grams into kg :
Imagine this, you hear an ambulance, The ambulance is about a mile off and it isn't very loud. As it gets closer it gets louder and louder when it passes you it gets loudest then it is very quiet. So yes, your hypothesis was correct.
Gravitational potential energy -> Kinetic energy -> Mechanical energy -> Electrical energy.
The water starts up (potential) and flows down (kinetic), the flowing water turns a big wheel (mechanical) which creates electricity (electrical).
Option ( A) is correct.
A quantum of light is called a photon.
Light is made of these packets of energy called as photons. These photons have zero rest mass.They possess momentum and travel with the velocity of light. They are electrically neutral. The energy of the photon is given by
E= h f
E= energy of photon
h= planck's constant
f= frequency of the photon
The higher frequency photons have more energy as compared to the lower frequency photons.
