The force between the charges is 60.47N
<u>Explanation:</u>
Given:
Charge, q₁ = 2.5 X 10⁻⁶ C
q₂ = 4.3 X 10⁻⁶ C
Distance, r = 0.04m
Force, F = ?
According to Coulomb's law:

where,
k = Coulomb's constant
and the value of k is 9 X 10⁹ Nm²/C²
On substituting the value we get:

Therefore, the force between the charges is 60.47N
Answer: Glad you ask!!
Its like a heat flow energy contained within a system that is responsible for its temperature.
Explanation:
deals with how heat is transferred between different systems and how work is done in the process
Hope this helps :)
Answer:
Difference is given below.
Explanation:
The main difference between beneficial and harmful friction is that beneficial friction is necessary for performing different activities while on the other hand, harmful effect of friction is destroy different parts of products and machines. examples of beneficial friction are walking, holding things, rubbing hands to produce heat, running etc whereas examples of harmful friction are destruction of sole, slipping, tearing of machine's part, Wet roads and Mudslides etc.
The kinetic energy will rise once the body comes back down. As it goes up, the potential energy increases while the kinetic energy decreases. Once the body is at its maximum height, the potential energy is at it’s highest. When it starts falling, it will gain kinetic energy and lose potential energy.
