Q1. If it takes 4.0 J of work to stretch a Hooke's-law spring 10.00 cm from its unstressed length, determine the extra work required to stretch it the additional 10.00 cm.
Q2. The speed of light is c = 3.0 x 10^8 m/s. This is quite fast. In this problem, you will explore just how fast.
Many communications satellites orbit the earth in geostationary orbits. (They appear to remain in the same positions in the sky for observers on the earth's surface.) If such a satellite orbits at a height of 40,000 km, estimation the time delay in a cell phone conversation by reason of the time it takes light to travel from one phone to the other via the satellite.
A thin, flexible metal plate attached at one end to the platform, can be used to measure mass. When the free end of the plate is pulled down and released, it vibrates in simple harmonic motion with a period that depends on the mass attached to the pl..
Sea Launch mission planners are going to launch their Russian launch vehicle from a Lo = 3 degrees into LEO with an inclination of 34 degrees and the longitude of ascending node of 124 degrees. Current LST at the launch site is 1140.
The magnitude of q is chosen to make the potential difference between spheres 430 V, with the inner sphere at higher potential. Compute q.
The latent heat of fusion
Two spherical objects have a combined mass of 200. The gravitational attraction between them is 8.01×10-6 while their centers are 21.0 apart.
A 346-, uniform, 1.04- bar is suspended horizontally by two vertical cables at each end. Cable A can support a maximum tension of 506.0 without breaking, and cable B can support up to 436.0. You want to place a small weight on this bar. What is the h..

A solid cylinder of radius 0.35 m is released from rest from a height of 1.8 m & rolls down the incline as shown. Find the angular speed of the cylinder when it reaches the horizontal surface?
The potential at location A is 392 V. A positively charged particle is released there from rest and arrives at location B with a speed vB. The potential at location C is 780 V, and when released from rest from this spot, the particle arrives at B wit..
