if you want to double the length of the time interval during which the ball stays in the air above the launch position, to what maximum height do you have to throw it?

It equals just about 6,300 km per hour each day an week

Sorry i don’t know what to do

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.

To a fellow spongebob-ian i will be glad to , the cheetah didn't get far on purpose because he's a cheetah  ( ͡° ͜ʖ ͡°)
