A particle of mass m is confined to move, without friction, in a vertical plane, with axes x horizontal and y vertically up. The plane is forced to rotate with constant angular velocity Omega about the y-axis. Find the quations of motion for x and y and solve them. Describe the possible motions.
a person whos weight is 80 kg is balancing on top of a basketball. the basketball itself is on the ground. what is the
an ideal gas in a balloon is kept in thermal equilibrium with its constant temperature surroundings. how much work is
If the electric field strength in air exceeds 3.0 multiplied by 106 N/C, the air becomes a conductor. Using this fact, determine the maximum amount of charge that can be carried by a metal sphere 3.1 m in radius.
q1. find out a capacitance and b maximum voltage that can be applied to a teflon-filled parallel- plate capacitor
An electron collides elastically with a hydrogen atom that is initially at rest. Assume all the motion occurs along a straight line. What fraction of the electron's initial kinetic energy is transferred to the atom? (Take the mass of the hydrogen ato..
Human tissue contains about 3·1027 electrons perkg of material. Suppose two humans are located 1960 km apart andeach has a mass of 60 kg. What will be the magnitude of the resulting force in N
The motor of a ski boat generates an average power of 7.70 104 W when the boat is moving at aconstant speed of 15 m/s. When the boat is pulling a skier at the same speed, the engine must generatean average power of 8.70 104 W.
