1. The figure shows a mass hanging from the ceiling. Find the tension in each of the three strings that hold the dough.

2. Two blocks of mass 3.5 kg and 8.00 kg are connected by a rope without mass passing over a
frictionless pulley. Inclined planes are frictionless. a) Determine the magnitude of the acceleration
of each block, and b) the tension in the rope.

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.
