Q. A 70.0-kg astronaut pushes to the left on a spacecraft with a force F in "gravity-free" space. The spacecraft has a total mass of 1.0 × 104 kg. During the push, the astronaut accelerates to the right with an acceleration of 0.36 m/s2. Determine the magnitude of the acceleration of the spacecraft.
Q. A total electric charge of 4.50 nC is distributed uniformly over the surface of a metal sphere with a radius of 22.0 cm. The potential is zero at a point at infinity. Find the value of the potential at 45.0 cm from the center of the sphere.
Cold fusion theory.
Young's double-slit experiment is performed with 570 nm light and a distance of 2.00 m between the slits and the screen. The tenth interference minimum is observed 7.64 mm from the central maximum. Settle on the spacing of the slits.
A canoe has a velocity of 0.54m/s southeast relative to the earth. The canoe is on a river that is flowing at 0.52m/s east relative to earth.
A worker pulls horizontally on a crate on a rough horizontal floor, causing it to move forward with constant velocity. In the figure, force is the pull of the worker and force is the force of friction due to the floor.
Assume after charging a 4.80 microF capacitor to 5 V you connect it to the second uncharged capacitor of 15 microF. What voltage will you voltmeter read across the second capacitor after repeating charge sharing process two times? State the answer..
A 68 kg person sits on a 4.0 kg chair. Each leg of the chair makes contact with the floor in a circle that is 1.2 cm in diameter . Find the pressure exerted on the floor by each leg of the chair, assume the weight is evenly distributed.
A wheel (radius = 0.20 m) is mounted on a frictionless, horizontal axle. A light rope wrapped around the wheel supports a 0.50-kilogram object, as shown below. When released from rest, the object falls with a downward acceleration of 5.0 m/s2. What i..
A spherical shell has an outside radius of 2.6cm and an inside radius of a. The shell wall has uniform thickness and is made of a material with density 4.70g/ cm3. The space inside the shell is filled with a liquid having a density of 1.23g/cm3.
Two charged Ping-Pong balls separated by the distance of 1.62 m exert an electric force of 0.0234N on each other. What will be the force if the objects are brought closer, to a separation of only 31.4 cm.
A 251 kg wooden raft floats on a lake. When a 70kg man stands on the raft, it sinks 4cm deeper into the water. When he steps off, the raft vibrates for a while.
A diving board oscillates with simple harmonic motion of frequency 3.23 cycles per second. What is the maximum amplitude with which the end of the board could vibrate in order that a pebble placed there not lose contact with the board during the o..
A piece of unpainted wood barely floats in a container partly filled with water. If container is sealed and then pressurized above atmospheric pressure, does the wood rise, sink, or remain at the similar level.
