Calculate the pressure 500m below the surface of water. Density of water is 1000kg/m^3. Take g=100m/s^2.

Applicate the formula:

p = ρ*g*d

Data:

p = Pressure = ¿?

ρ = Density = 1000 kg/m³

g = Gravity = 9,81 m/s²

d = Distance = 500 m

Replacing:

p = 1000 kg/m³ * 9,81 m/s²  *500 m

Resolving:

p = 4905000 Pa

The pressure at that deep is 4905000 Pa.

The objects do not reach terminal velocity         there is not enough time from the time the object falls from when it hits the ground to achieve terminal velocity. an object must be placed higher to achieve terminal velocity in order to be in free fall.

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
