Consider the RLC circuit with R = 16 ohms, L = 8 H, C = 1/40 F, and E(t) = 17 cos 2t V. Determine the current in the circuit for t > 0, given that at t = 0, the capacitor is uncharged and there is no current flowing.

An alternating current E(t)=120sin(12t) has been running through a simple circuit for a long time. The circuit has an inductance of L=0.28 henrys, a resistor of R=9 ohms and a capacitor of capcitance C=0.044 farads.What is the amplitude of the current I?

Pls help ASAP

charge Q  acts as a point charge to create an electric field.Its strength, measured a distance of  30 cm away, is 40 N/C.What is the magnitude of the electric field strength that you think you would expect to be measured at  a distance of 60 cm away?

An amusement park has two ferris wheels that both load passengers at the bottom, 3 m above the ground. Both wheels require 40 seconds to complete one revolution. The larger ferris wheel has a diameter of 25 m and the smaller ferris wheel has a diameter of 10 m. The height of a passenger on each wheel can be expressed in the form h(t) = a cos[b(tc)] + d, where h(t) is the height above the ground in metres t seconds after the ride begins. 25 m 3m 14 O a and b O a and d TOT Ob and c Oc and d 10 m 3 m A 76 If the ferris wheels have the same period of rotation, then the two parameters that must be the same in the two functions are Ground

A tank initially contains 300 gallons of water with 50lbs of salt disolved in the water. A brine solution is pumped into the tank at a rate of 5gal/min and the wellstirred mixture is pumped out of the tank at the same rate. The concentration of salt in the inflow is variable and is given by cin = (2 + sin(t/4))lbs/gal. Find the amount of salt in the tank at any time t.
