Get college assignment help at uniessay writers A circuit is constructed with two capacitors and an inductor as shown. The values for the capacitors are: C1 = 497 μF and C2 = 275 μF. The inductance is L = 293 mH. At time t =0, the current through the inductor has its maximum value IL(0) = 194 mA and it has the direction shown. 2) What is Q1(t1), the charge on the capacitor C1 at time t = t1 = 26.4 ms? The sign of Q1 is defined to be the sameas the sign of the potential difference Vab = Va – Vb at time t = t1. 3)What is Vbc(t1)= Vb – Vc, the voltage across the inductor at time t1 = 26.4 ms? Note that this voltage is a signed number. 4) What is Q1,max, the magnitude of the maximum charge on capacitor C1?

A 75kg meteorite buries itself 5.0 meters into soft mud. The trajectory of the meteorite is vertical, paving its way through the mud until it finally comes to rest 5 meters below the mud-ground level. The magnitude of the force between the meteorite and the mud is given by F(y)=abs value (640 N/m^3)y^3), where y is the depth in the mud. Through application of the work energy theorem determine the meteorite’s initial speed just before impacting into the mud. Be sure to specify at what location you decide to take the gravitational PE level=0 in solving this problem

At time t=0 a grinding wheel has an angular velocity of 26.0 rad/s. It has a constant angular acceleration of 29.0 rad/s^2 until a circuit breaker trips at time t = 2.50 s. From then on, the wheel turns through an angle of 440 rad as it coasts to a stop at constant angular deceleration. Through what total angle did the wheel turn between and the time it stopped? At what time does the wheel stop? What was the wheel’s angular acceleration as it slowed down?

A loudspeaker of mass 19.0 is suspended a distance of = 1.40 below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of = 2.50 .

As a space craft approaches a planet, the rocket engines on it are fired to slow it down so it will go into orbit around the planet. The spacecraft’s mass is 291 kg and the thrust (force) of the rocket engines is 59 N. If the speed of the spacecraft must be decreased by 128 m/s, how long must the engines be fired. (Ignore the change in mass due to the rocket engines firing).
