Two identical conducting spheres each having a radius of 0.500 cm are connected by a light 1.90 m long conducting wire. A charge of 65.0 µC is placed on one of the conductors. Assume the surface distribution of charge on each sphere is uniform. Determine the tension in the wire.
A turntable has moment of inertia 0.0300 kg m2 and is rotating at 25.0 rev/min. A 0.300 kg ball of clay is dropped vertically onto the turntable and sticks at a point 0.100 m from the center. What is the new rate of rotation of the turntable?
A cube of ice is taken from the freezer at -8.5°C and placed in a 104 g aluminum calorimeter filled with 309 g of water at room temperature of 20°C. What was the mass of the ice cube
A covex lens of focal length 10 cm placed 40 cm in front of aconcave lens of focal length 25 cm.A small object is placed 20 cmin front of the convex lens calculate the location of the finalimage relative to the second lens. Include a ray diagram
An electromagnetic velocity filter (sometimes called a Wien filter) is used in a variety of experiments and other applications, such as electron microscopes, in which we need a beam of charged particles all going at the same speed. Generally the s..
Since force is dp/dt, the force due to radiation pressure reflected off of a solar sail can be calculated as 2 times the radiative momentum striking the sail per second. In the vicinity of Earth's orbit around the Sun, the energy intensity of sunl..
An electron moves with a velocity of (4*10^6 m/s, 90degrees) through a magnetic field of (0.50 T, 220degrees). What is the magnetic force acting on it?
A series RLC circuit has components with the following values: L = 22.0 mH, C = 94.0 nF, R = 30.0 ?, and ?Vmax = 100 V, with ?v = ?Vmax sin ?t. Find the amplitude of the voltage across the inductor
A 0.15 kg baseball is hit by a baseball bat. Right before it is hit, the ball's speed is 30 m/s, find the magnitude of the net impulse that is applied to the ball
In proton-beam therapy, a high-energy beam of protonsis fired at a tumor. The protons come to rest in the tumor,depositing their kinetic energy and breaking apart thetumor’s DNA, thus killing its cells. For one patient, it isdesired that 0.10 J of pr..
