Determine work should the total external force
A 6100-kg satellite is in a circular earth orbit that has a radius of 2.7x10^7 m. A net external force must act on the satellite to make it change to a circular orbit that has a radius of 5.6x10^6 m. What work must the net external force do?

Two equally charged insulating balls each weigh 0.40 g and hang from a common point by identical threads 45 cm long. The balls repel each other so that the separation between their centers is 6.6 cm. What is the magnitude of the charge on each bal
An electric vehicle starts from rest and accelerates at a rate of 2.3 m/s2 in a straight line until it reaches a speed of 16 m/s. The vehicle then slows at a constant rate of 1.1 m/s2 until it stops. (a) How much time elapses from start to stop? (
A small segment of wire contains 10 nC of charge. The segment is shrunk to one-third of its original length. A proton is very far from the wire. What is the ratio Ff/Fi of the electric force on the proton after the segment is shrunk to the force b
Consider Compton scattering event in which the scattering photon has an energy of 120 keV and the recoiling electron has an energy of 40 keV. a) Calculate the wavelength of the incident photon,
Sunlight strikes the surface of a lake. A diver sees the Sun at an angle of 28.4° with respect to the vertical. What angle do the Sun's rays in air make with the vertical?
String A is stretched between two clamps separated by distance L. String B, with the same linear density and under the same tension as string A, is stretched between two clamps separated by distance 3L.
The distance of light speed in a 24hr p. x 365 days up to 1 thousand years as a constant, would equal a finite distance and time to reach that distnation. Suppose; it took to reach the same distance in a day how fast would that speed of light be?
A piston (with mass M = 2.0 kg) in a car engine is in vertical simple harmonic motion with amplitude A = 5.0 cm. If the engine is running at 405.265452313 rad/s, (a) What is the maximum velocity (m/s) of the piston?
Assuming no heat is lost to the surroundings and neglibible heat loss from the container. Determine the total change in entropy as a result of the mixing process.
A bird stands on a dc electric transmission line carrying 2900 A. The line has 2.6×10^-5 resistance per meter, and the bird's feet are 3.9 cm apart. What is the potential difference between the bird's feet?
