Suppose we have an RLC circuit with a resistor of 100 milliohms (0.1 ohms), inductor of 50 millihenries (0.05 henries), and a capacitor of 5 farads, with constant voltage. a) Set up the ODE equation for the current I. b) Find the general solution. Write your final answer as a single term with a cosine but no sine. c) Find a particular solution so that I(0)

At very high pressures, gases become and will eventually a) more dense; become hotter b) more dense; change to a liquid or solid c) less dense; combust d) less dense; turn into a liquid

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?
