The small slider of mass m = 0.73 kg is released from rest while in position a and then slides along the vertical-plane track. the track is smooth from a to d and rough (coefficient of kinetic friction μk = 0.26) from point d on. determine (a) the normal force nb exerted by the track on the slider just after it passes point b, (b) the normal force nc exerted by the track on the slider as it passes the bottom point c, and (c) the distance s traveled along the incline past point d before the slider stops. the distance r = 1.10 m.

The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space. assume that the membrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has a magnitude of 7.0 × 10-6 c/m2. (a) what is the magnitude of the electric field within the cell membrane? (b) find the magnitude of the electric force that would be exerted on a potassium ion (k+; charge = +e) placed inside the membrane.
