Suppose the coefficient of static friction between the book and the desk is 0.6020.602 and the coefficient of kinetic friction is 0.3270.327 . how much force is needed to begin moving the book?

Ihave no idea sorry

Hypothesis. why don’t you know this? i learned this stuff in like 5th grade

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.

Amicroscope, because these cells are so small that you would not be able to see them, or what they attack without it.
