Aboat with a horizontal tow rope pulls a water skier. she skis off to the side so that the rope makes an angle of 10 degrees with the forward direction of motion. if the tension in the room is 200 n, how much work does the rope do on the skier during a forward displacement of 100 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.

A20 cm long spring is attached to a wall. the spring stretches to a length of 22 cm when you pull on it with a force of 100 n. what is the spring constant
