To solve this problem, we have to use the formula:
E = h f
where E is total energy, h is Plancks constant
6.626x10^-34 J s, f is frequency
f = E / h
f = 3.686 × 10−24 J / (6.626x10^-34 J s)
<span>f = 5.56 x 10^9 Hz</span>
The gravitational potential energy
gpe = mgh

Because if they were in the inside, then they would not be able to sexually reproduct and could not have offspring.
no, work is = force * distance or displacement
