0.200cm= 0.002km
0.002*60=0.12km/min
0.12*60=7.2km/h
7.2*24=172.8km/day
172.8*365=63072km/year
<h2>The frequency depends upon the source energy of electromagnetic waves</h2>
Explanation:
The energy of electromagnetic wave is
E = h ν
E is the energy of source emitting the waves
here h is Plank's constant
and ν is used for the frequency of the electromagnetic wave
Thus the frequency of wave depends upon the energy of electromagnetic source . Because h is constant .
Answer:
Reaction force = Weight
the force exerted by A on B is equal.
