Answer:
C. The floor pushing back against the foot
Explanation:
If the roadway is wet and the cars starts to skid, one should slow down by shifting to lower gear. The correct option is B.
<h3>What are gears?</h3>
A gear is component used to transmit motion. They are used in cars, trucks, machines, bicycles, etc.
For a car to avoid skidding on the wet roads, one must drive the car slowly. This can be done by shifting the gear to the lower one. This will help car to keep balance when brakes are applied on wet roads.
Thus, the correct option is B.

Answer:0,002 = 2 x 10⁻³
Explanation:
0,002 = 2 / 1000 = 2 / 10³ = 2 x 10⁻³
Potential energy is highest at the top of the loop, and kinetic energy is highest at the bottom of the loop.
A particle with charge -40.0nC is on the x axis at the point with coordinate x=0 . A second particle, with charge -20.0 nC, is on the x axis at x=0.500 m.
No, there is no point at a finite distance where the electric potential is zero.
Hence, Option D) is correct.
What is electric potential?
Electric potential is the capacity for doing work. In the electrical case, a charge will exert a force on some other charge and the potential energy arises. For example, if a positive charge Q is fixed at some point in space, any other positive charge when brought close to it will experience a repulsive force and will therefore have potential energy.
It is also defined as the amount of work required to move a unit charge from a reference point to a specific point against an electric field.
