Q. An electron is released from rest at the negative plate of a parallel plate capacitor. The charge per unit area on each plate is = 2.6 x 10-7 C/m2, and the plates are separated by a distance of 1.4 x 10-2 m. How fast is the electron moving just before it reaches the positive plate?
Q. The elastic energy stored in your tendons can contribute up to 35 % of your energy needs when running. Sports scientists have studied the change in length of the knee extensor tendon in sprinters and nonathletes. They find (on average) that the sprinters' tendons stretch 41 {rm mm}, while nonathletes' stretch only 33 {rm mm}. The spring constant for the tendon is the same for both groups, 32 {rm {N}/{mm}} . What is the difference in maximum stored energy between the sprinters and the nonathletes?
A charge of -3.80 nC and a charge of -6.00 nC are separated by a distance of 60.0 cm. Find out the position at which a third charge of +7.30 nC could be placed so that the net electrostatic force on it is zero.
A rectangular loop of wire has dimensions 0.5m by 0.3m. The loop is pivoted at x axis and lies in the xy plane. A uniform magnetic field of magnitude 1.5 T is directed at an angle of 40° with respect to the y axis with field lines parallel to the ..
A simple harmonic oscillator consists of a block of mass 4.kg attached to a spring of spring constant 153 N/m. When t = 2 s, the position and velocity of the block are x = +0.129 m and v = +3.415 m/s.
A stretched rubber band has the length of 0.04 m and a fundamental frequency of 462 Hz. What is the speed at which waves travel on the rubber band.
A grindstone of radius 4 m is initially spinning with an angular speed of 8 rad/s. The angular speed is then increased to 10 rad/s over the next 4 seconds. Imagine that the angular acceleration is constant.
A solid, frictionless cylindrical pulley with a mass of 3kg and a 0.420 m radius is used to draw water from a well. A 1.50kg bucket is attached to a cord that is wrapped around the pulley. If the bucket starts from rest at the top of the well and ..
You have a 56.9-mF capacitor initially charged to a potential difference of 10.1 V. You discharge the capacitor through a 4.77-Ω resistor. What is the time constant? After what multiple of the time constant does the potential difference reach 2.47 V.
