Calculate the magnitude of B when the force on wire. The time constant of an RC circuit is 5.5 s. How much time t is required for the capacitor (uncharged initially) to gain one-half of its full equilibrium charge.
If a vehicle is traveling at velocity v and takes a distance d to stop, then how fast is a vehicle traveling if it takes a distance of 3d to stop. suppose mass and acceleration are equal.
You're 6.0 m from one wall of a house. You want to toss a ball to your friend who is 6.0 m from the opposite wall. The throw and catch each occur 1.0 m above the ground. find minimum speed will allow the ball to clear the roof
a marble column of a cross sectional area 1.5 m^2 suports a mass of 24000 kg, what is the stress within the ciolumn? N/m^2
Two capacitors are connected in series. Let 3.40mF be the capacitance of first capacitor, 5.30mF the capacitance of the second capacitor, and Vab= 57.0 V the potential difference across the system. A)Calculate the charge on each capacitor. B)Calcu..
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 during an angle of 440 rad as it coasts to a..
