Suppose a certain battery has an internal emf of 9.00 v but the potential difference across its terminals is only 80.0 % of that value. part a if that battery is connected to a 44.0 μf capacitor, how much energy is stored when the capacitor is fully charged? express your answer with the appropriate units. ueu e = nothing nothing request answer

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.
