If the pressure (P) of an object that acts on a certain surface = (m g)/A . Where (m) is the mass of object, (g) is the acceleration due to gravity and (A) is basic area of the object. So the unit used for measuring the pressure in the British system is * kg/ foot. s^2
pound/ foot. s^2
g/ cm. s^2
pound. foot/ s2

The two metal spheres in the figure are connected by a metal wire with w switch in the middle. initially the switch is open. sphere 1, with the larger radius, i'd given a positive charge. sphere 2, with the smaller radius, is neutral. then the switch is closed. afterward, sphere 1 has charge q1, is at potential v1 and the electric field strength at its surface is e1. the values for sphere 2 are q2, v2, and e2. a. is v1 < ,> , or = to v2? explain. b. is q2 < , > , or = explain? c. is e1 < ,> ,or = to e2? explain?
