According to Newton;s Second Law of motion, F = ma. Acceleration is the change of velocity per unit time. Since there is no change of velocity, then acceleration is equal to zero. Consequently, the net force F is also equal to zero. The net force is equal to the sum of all the forces acting on the body. These forces are the horizontal force and the frictional force. They are acting in opposite directions. So, the sum must be
F = 0 = Horizontal - Frictional
0 = 100 N - Frictional
Frictional force = 100 N
The two Health and safety risk at the scene are:
1. To deal with Chemicals.
2. To deal with Electricity.
<h3>What are Healthy and safety risk?</h3>
The healthy and safety risk at the scene or office is described as safety hazards that has to be taken when employers are working in office in some mechanical or electrical workshops.
Employers need to e follow some healthy and safety risk while working in office like:
1. Chemicals : When employees have to handle harmful or dangerous chemicals as part of their work. To safety safe the must wear protective clothing.
2. Electrics - Electrical safety is an important issue in workplace , especially where there is a risk that heavy-duty equipment might cause electric shock.
These are some safety hazards employees must follow.

Answer:
Energy exists in different forms, all of which can be classified as either potential energy or kinetic energy. Potential energy is energy stored in an object due to its position or arrangement. Kinetic energy is energy of an object due to its movement - its motion.
so it would be the other way around
