You have two large parallel circular plates each with area a in vacuum. one plate has a charge +q and the other plate has charge -q. the plates lie right on top of each other and the distance between the plates is d. assume that the radius of the plate is significantly larger than the distance between the plates. calculate: a) capacitance (neglect fringing fields) b) electric field at all points along the axis (perpendicular to the plates) which lie in between the two plates. c) potential at all points along the axis (perpendicular to the plates) which lie in between the two plates d) electric field at point a along the axis which is at a distance 0.5d from the right plate see figure below. solve using gauss's law.

Askydiver weighing 140 lb (including equipment) falls vertically downward from an altitude of 19,000 ft and opens the parachute after 18 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.55|v| when the parachute is closed and is of magnitude 14|v| when the parachute is open, where the velocity v is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. (a) find the speed of the skydiver when the parachute opens. (b) find the distance fallen before the parachute opens. (c) what is the limiting velocity vl after the parachute opens? (d) determine how long the sky diver is in the air after the parachute opens. (e) plot the graph of velocity versus time from the beginning of the fall until the skydiver reaches the ground.

All the simple machines make work easier to do by changing the or of a force. a. size; type b. work; type c. size; direction d. type; direction
