Q. A series RL circuit with L = 3.00 H and a series RC circuit with C = 3.00 μF have equal time constants. If the two circuits contain the similar resistance R,
(a) what is the value of R and
(b) what is the time constant?
At one instant a bicyclist is 53m due east of a park's flagpole, going due south with a speed of 12m/s. Then 37s later, the cyclist is 53m due north of the flagpole, going due east with a speed of 12m/s. For the cyclist in this 37s interval.
A rocket blasts off vertically from rest on the launch pad with an upward acceleration of 2.30. At 10.0 after blastoff, the engines suddenly fail, which means that force they produce instantly stops.
The street automobile with the greatest acceleration is the Tempest. It has an acceleration of 6.89m/s2. Suppose the car accelerates from the rest to a final speed of 96.5km/h. How long does it take Tempest to reach this speed.
A student (m= 75kg) falls freely from rest and strikes the ground. During the collision with ground, he comes to rest in a time of 0.040s.
The length of a string is 322 cm. It is held fixed at each end. The string vibrates in seven sections; such as the string has seven antinodes, and the string vibrates at 160 Hz.
What is the average speed of a rider on this Ferris wheel.
Find out the gravitational potential energy
Eight identical, non-interacting particles are placed in a cubical box of sides L = 0.2 nm. Find the lowest energy of the system (in electron volts) and list the quantum numbers of all occupied states if (a) particles are electrons and (b) particles..
What minimum force is necessary to start the block moving up the wall? (Hint: The static frictional force is now directed down the wall.)
The drawing shows one horizontal wire with the current going up and one vertical wire with the current going to the right. Point A is dH to the right and dV above the intersection. Point B is dH to the left and dV below the intersection.
What must the charge (sign and magnitude) of the particle of mass 1.42 g be for it to remain stationary when placed in a downward-directed electric field of magnitude 650 N/C.
Three pendulums with strings of the same length and bobs of the same mass are pulled out to angles q1, q2 and q3 correspondingly and released. The approximation sin q = q holds for all three angles, with q3 > q2 > q1. How do angular frequencies of th..
