You wish to build a time delay circuit using a 75h inductor. you want the voltage across the inductor to fall to 3.0v from an initial voltage of 12v in a period of 2.0s. what resistance must be used in the circuit? select one of the following: (a) 0.019ω (b) 110ω (c) 150ω (d) 52ω (e) 11ω

Under normal temperature and pressure conditions, what type of rock could be formed from weathering in erosion of metamorphic rock

Aquantity of gas has a volume of 1.5 m3 and an absolute pressure of 95 kpa. when the gas is compressed to a volume of 0.5 m3, what is the new absolute pressure of the gas? (assume that there’s no change in temperature.)

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?
