Anozzle with a radius of 0.28 cm is attached to a garden hose with a radius of 0.85 cm. the flow rate through hose and nozzle is 0.55 l/s. no attempt 50% part (a) calculate the maximum height to which water could be squirted with the hose if it emerges from the nozzle in m. b) calculate the maximum height (in cm) to which water could be squirted with the hose if it emerges with the nozzle removed, assuming the same flow rate.

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.
