Q1. A diving board oscillates with simple harmonic motion of frequency 3.36 cycles per second, What is the maximum amplitude with which the end of the board can vibrate in order that the pebble placed there not lose contact with the board during oscillation?
Q2. A baseball leaves a pitcher's hand horizontally at the speed of 152km/h. The distance to the batter is 18.3m. (Ignore the effect of air resistance.) (a) How long does the ball take to travel the first half of that distance? (b) The second half? (c) How far does the ball fall freely during the first half? (d) Throughout the second half?
Assume, instead, that the observer had been moving away from Earth with a speed of 0.80c. How much time would observer have measured for the car to be filled in this case.
A small spherical insulator of mass 8 x 10 kg and change +0.600 micro Coulomb is hung by a tin wire of negligible mass. A charge of -0.900 micro Coulomb is held 0.150 m away the sphere and straight to the right of it, so the wire makes the angle with..
A toroidal solenoid has a mean radius of 11.0 cm and a cross-sectional area of 5.00 cm2 and is wound uniformly with 100 turns. A second coil with 500 turns is wound uniformly on top of the first. What is the mutual inductance of these coils.

A continuous line of charge lies along an x axis, extending from x = +x0 to positive infinity. The line carries charge with the uniform linear charge density λ0. What are the magnitude and direction of the electric field at the origin.
A 0.34 kg iron horseshoe that is initially at 616 ?C is dropped into a bucket containing 25 kg of water at 28 ?C. What is the final equilibrium temperature? Avoid any energy transfer to or from the surroundings and assume the specific heat of iron is..
How long does it take for the grinding wheel to stop ? Through how many radians has the wheel turned during the interval found in.
A 2.1-kg block is released from rest and allowed to slide down a frictionless surface and into a spring. The far end of the spring is attached to a wall, as shown. The initial height of the block is 0.36 m above the lowest part of the slide and the s..
Oxygen (O2) gas within a piston-cylinder assembly undergoes an expansion from a volume V1= 0.02 m3 to volume V2 = 0.03 m3. The relationship between pressure and volume throughout the procedure is p=AV-1+B, where A= 0.06 bar.m3 and B= 3.0 bar. For the..
