Answer:
9.216 x 10^-8 N
Explanation:
q1 = 1.6 x 10^-19 C
q2 = - 1.6 x 10^-19 C
r = 5 x 10^-11 m
(a) The electrostatic force is given by
F = k q1 q2 / r^2
F = ( 9 x 10^9 x 1.6 x 10^-19 x 1.6 x 10^-19) / (5 x 10^-11)^2
F = 9.216 x 10^-8 N
This force is attractive in nature, as both the charges are opposite in nature.
The wavelength of the radio wave is 0.303 m.
<h3>
Wavelength</h3>
The wavelength of the wave is the distance traveled by the wave.
c = fλ
where;
- c is speed of light = 3 x 10⁷ m/s
- f is frequency
- λ is wavelength
λ = c/f
λ = (3 x 10⁷ ) / (99 x 10⁶)
λ = 0.303 m
Thus, the wavelength of the radio wave is 0.303 m.

Explanation:
potential energy ===> kinetic energy
when an object is stretched there will be a stored energy in it enough to react to the upcoming change
that is the potential energy
<em>similar</em><em> </em><em>to</em><em> </em><em>a</em><em> </em><em>stretched</em><em> </em><em>elastic</em><em> </em><em>band</em>
kinetic energy is the energy on a moving object
*If a kinetic energy takes place there must gave been a potential energy before*
Conserved
Explanation:
The first law of thermodynamics states that energy in a systems is "conserved".
This law is the law of conservation of energy of energy. It states that:
"in an isolated system, energy can neither be created nor destroyed but it is transformed from one form to another".
- This simply shows that energy is conserved in an isolated system.
- In an isolated system, there is no exchange of energy with the environment.
- Also, energy is neither formed nor destroyed but transformed.
