A 0.25kg soccer ball is rolling at 3.0m/s toward a player. The player kicks the ball back in the opposite direction and gives it a velocity of -12m/s. What is the average force between the ball and foot if the interaction lasts 0.027s?

It's because 3 if it was 10 it wouldn't look right do it goes up to 4d

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.

Because the sun is the biggest and if the sun orbits the earth we will be dead probably
