A 1.00uF capacitor is connected in parallel with a 2.00uF capacitor. The 1.00uF capacitor carries a charge of +10.00uC on one plate, which is at a potential of 50.00V. FInd
(a) the potential on the negative plate of the 1.00uF caacitor;
(b) the equivalent capacitance of the two capacitors;
(c) the charge on the negative plate of the 2.00uF capacitor.
If it takes 3 golf balls to equal the mass of one tennis ball, what weight of tennis balls do you require equalling the number of golf balls in one kilogram of golf balls.
An elevator accelerates upward at 1 m/s2. When the elevator is moving upward at 2 m/s, a bolt drops from the ceiling which is 2.5 m above the?
A tennis ball is thrown toward a vertical wall with a speed of 22.0 m/s at the angle of 40.0° above the horizontal. The horizontal distance between the wall and the point where the tennis ball is released is 28.0 m.
If the coefficient of friction between road and tires on a rainy day is 0.100, what is the minimum distance in which the car will stop?
A bird sitting in a tree is travelling at 40 km/s relative to the faraway Sun. When the bird drops to the ground below, does it still go 40 km/s, or does this speed become zero.
A 12.0-{rm kg} box resting on a horizontal, frictionless surface is attached to a 5.00-{rm kg} weight by a thin, light wire that passes over a frictionless pulley). The pulley has the shape of a uniform solid disk of mass 2.40 {rm kg} and diameter 0...
At rest when constructed, the ring is set rotating about its axis so that the people inside experience effective free-fall acceleration equal to g. The rotation is achieved by firing two small rockets attached tangentially to opposite points on the r..
A 10.60 weather rocket generates a thrust of 220. The rocket, pointing upward, is clamped to the top of the vertical spring. The bottom of the spring, whose spring constant is 450, is anchored to the ground.
A rope of negligible mass is wrapped around a 225 kg solid cylinder of radius 0.40 m. The cylinder is suspended some meters off the ground with its axis oriented horizontally, and turns on that axis without friction.
What is the least coefficient of friction between the beam and the wall for the beam to remain in static equilibrium.
For a spherical celestial object of radius R, acceleration due to gravity g at a distance x from the center of the object is g = g0R2/x2, where g0 is the acceleration due to gravity at the object's surface and x > R.
A small body of mass 0.28 kg is undergoing simple harmonic motion of amplitude 4.0 cm and period 0.10 s. What is the maximum value of the force acting on it? If the oscillations are produced by a spring, what is the spring constant?
