Design a decorative "mobile" to consist of a low-mass rod of length 0.46 m suspended from a string so that the rod is horizontal, with two balls hanging from the ends of the rod. At the left end of the rod hangs a ball with mass 0.716 kg. At the right end of the rod hangs a ball with mass 0.222 kg. You need to decide how far from the left end of the rod you should attach the string that will hold up the mobile, so that the mobile hangs motionless with the rod horizontal ("static equilibrium"). You also need to determine the tension in the string supporting the mobile.
(a) What is the tension in the string that supports the mobile?
tension = N
(b) How far from the left end of the rod should you attach the support string?
distance from left end = m
How much energy was released in an explosion
what is the bee's speed at once afterward.
Compute the acceleration of a 0.55m diameter car tire while the car is travelling at a constant speed of 25m/sec. b. compare this with the acceleration experienced by a jet car tire diameter 1 when setting a land speed record of 310m/sec.
A convex spherical mirror with a radius of curvature of 14.5 cm creates a virtual image one half the size of the real object. Where is the object.
A standing observer perceives a train whistle to have a frequency of 300 Hz. calculate the frequency of the sound waves emitted from the train
A damped mass-spring system oscillates at 280 Hz. The time constant of the system is 2.0 s. At t = 0, the amplitude of oscillation is 8.4 cm and the energy of the oscillating system is then 84 J.
Two large parallel plates are separated by 0.90cmand carry uniform charge densities equal in magnitude and opposite in sign, Find the magnitude of the charge density on the plates
A uniform board is leaning against a smooth vertical wall. The board is at an angle above the horizontal ground. The coefficient of static friction between the ground and the lower end of the board is 0.620.
You push a 2.7 kg box with a force of 23.8 N along a level floor, but a frictional force of 3.3 N opposes the motion
