You want to consider how to improve the current generating capability of the machine during an exercise by varying the spinning speed of the wheel and the friction force between the paper stack and the wheel. Under the assumption that the energy burning rate during an exercise is constant at 500 Cal/h and the exercise time stays the same, considering the wheel's spinning speed and the friction force are. Required:
Will the average current increase if the friction force is increased? And why?

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

i believe the answer is a hope it and is correct

find the sum of the two horizontal vectors and the sum of the two vertical vectors
