A 1000kg boulder with a 20m radius is rolling down a ramp to crush Indiana Jones. If the ball rolls from rest and then without slipping reaches a speed of 10m/s at the end of the ramp, in 2.0s, what is the angular acceleration of the ball as it rolls down the ramp?

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.

He sandals were out in the sun so the got hotter. which is why her feet felt hot.

Iam on that question know can you tell me the answer i am realy strruglingasap

Ithink the answer is fusion
