Q. A thin, uniformly charged spherical shell has a potential of 720 V on its surface. Outside the sphere, at a radial distance of 29.0 cm from this surface, the potential is 434 V.
Calculate the radius of the sphere.
Q. The springs of a 1100 kg car compress 3.5 mm when its 68 kg driver gets into the driver's seat. If the car goes over a bump, what will be the frequency of vibrations?
A jet is circling an airport control tower at a distance of 16km. An observer in the tower watches the jet cross in front of the moon. As seen from the tower, the moon subtends an angle of 9.50x10-3 radians. Find out the distance traveled (in mete..
It has been suggested that rotating cylinders about 10 mi long and 5.0 mi in diameter be placed in space and used as colonies. What angular speed should such a cylinder have so that the centripetal acceleration at its surface equals the free-fall ..
A person of mass 75 stands at the center of a rotating merry-go-round platform of radius 2.8 and moment of inertia 920. The platform rotates without friction with angular velocity 1.78. The person walks radially to the edge of the platform. Compute a..
A weightlifter has been given a barbell to lift. One end has a mass of 5.05 kg while the other end has a mass of 5.20 kg. The bar is 0.20 m long. (Consider the bar to be massless, and assume that the masses are thin disks, so that their centers of ma..
A 1.35 block is attached to a spring with spring constant 14. While the block is sitting at rest, a student hits it with a hammer and almost instantaneously gives it a speed of 50. What are The block's speed at the point where = 0.750 A.
Find the total work done on the car
Two cars are traveling along a straight road. Car A maintains a constant velocity of 110 km/h and car B maintains a constant speed of 110 km/h. At t= 0, car B is 45 km behind car A. How far would car A travel from t = 0, before it is overtaken by c..
Calculate P necessary to just start opening the 2 m wide gate.
A tuning fork vibrating at 516 Hz falls from rest and accelerates at 9.80 m/s2. How far below the point of release is the tuning fork while waves with a frequency of 489 Hz reach the release point? Take the speed of sound in air to be 340 m/s.
Light of wavelength 470 nm in air enters a fishbowl filled with water, then exits by the crown-glass wall of the container. Find the wavelengths of the light (a) in the water and (b) in the glass.
When one gallon of gasoline is burned in a car engine, 1.18 x 10^8 J of internal energy is released. Suppose that 0.99 x 10^8 J of this energy flows directly into the surroundings (engine block and exhaust system) in the form of heat. If 6.0 x 10^5 J..
A cosmic-ray proton in interstellar space has an energy of 17.0 MeV and executes a circular orbit having a radius equal to that of Jupiter's orbit around the Sun (7.78 x 10^11 m). What is the magnetic field in that region of space.
