33. (a) If ma-20 kg and mo: 10 kg. Determine the acceleration of each block (b) If initially
MA is a rest 1.250m from the edge of the
table, how long does it take to reach the edge
of the table if the system is allowed to
move freely ? (C) If mp=1.0kg, how large
must ma be if the acceleration of the
system is to be kept at 100g?

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.

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat
