Slader Two very extensive and very thin metal plates are parallel and close to each other. One is on the y-z plane at x = 0 and the other is parallel to the y-z plane at x = 1cm. The inner surface of the left plate is negatively charged and the inner surface of the right plate is positively charged. The magnitude of the surface charge density (σ) is 7.00 x 10-22 C/m2 on each plate. (a) Find the electric field (E) for points x < 0. (b) Find E for points 0 < x < 1cm. (c) Find E for points x > 1cm.

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.

In what direction does an applied force move an object

Aballoon is rising vertically upwards at a velocity of 10m/s. when it is at a height of 45m from the ground, a parachute bails out from it. after 3s he opens his parachute and decelerates ata a constant rate 5m/s.when. (a) what was the height of the parachutist above the ground when he opened his parachute? (b)how far is the parachutist from the balloon at t=3s? (c)with what velocity does the parachutist hit the ground? (d)after how long does the parachutist hit the ground after his exist from the balloon?
