Aheavy rope with a uniform mass density, mu, is fixed to a support in a ceiling and allowed to hang vertically. if you grab hold of the hanging end of the rope and shake it back and forth, you can set up a wave pulse that will travel up the rope. what happens to the speed of the wave pulse as it travels up the heavy 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.
