The molecules tend to speed up and move faster throughout the substance once thermal energy increases. This is evident whenever we heat up water as its molecules tend to move faster throughout the water as thermal energy tends to increase.
Answer:
The magnitude of the electrostatic force that acts on each sphere is 1.027 N
Explanation:
Given;
distance of separation of the two spheres, r = 0.3 m
number of electrons on the spheres = 2 x 10¹³ e
charges on each sphere, q = 2 x 10¹³ x 1.602 x 10⁻¹⁹ C = 3.204 x 10⁻⁶ C
According to coulomb's law;
where;
F is the electrostatic force between the spheres
K is coulomb's constant = 9 x 10⁹ Nm²/c²
Therefore, the magnitude of the electrostatic force that acts on each sphere is 1.027 N
968 j or kg because it cannot lose any of it energy and cannot gain any extra mass from nothing
