Answer:
When a bullet is fired from a gun, the gun exerts a force on the bullet in the forward direction. This is force is called as the action force. The bullet also exerts an equal and opposite force on the gun in the backward direction. Therefore a gun recoils when a bullet is fired from it.
<u>Answer</u>
25 Volts
<u>Explanation</u>
Ohm's law states that the current flowing though a fixed resistor is directly proportional to the voltage drop across it.
V ∝ I
V = RI Where R is the resistance.
V = 0.5 × 50
= 25 V
Atoms have an overall charge that is neutral because atoms have equal number of positive protons and negative electrons thus they cancel each other out. This always true for atoms that are stable and in equilibrium.
Friction between two flat surfaces is distinguished as being kinetic friction.
