1. The problem statement, all variables and given/known data Two atomic clocks are synchronized. One is placed on a satellite which orbits around the earth at high speeds for a whole year. The other is placed in a lab and remains at rest with respect to the earth. You may assume both clocks can measure time accurately to many significant digits.'
a) Will the two clocks still be synchronized after one year?
b) Imagine the speed of light is much lower than its actual value. How would the results of this experiment change if the speed of light was only twice the average speed of the satellite? Explain your reasoning using a calculation.
The coefficient of kinetic friction between the block and the surface is mu = .2. Find the acceleration of the block.
A 0.271 kg bead slides on a curved wire, starting from rest at point A as shown in the figure. The acceleration of gravity is 9.8 m/s2 . If the wire is frictionless, find the speed of the bead at B. Find the speed of the bead at C. A5.58 m B C1.09 m

An alpha particle (m = 6.68×10?27 kg, q = 3.20×10?19 C) circularly orbits a charged sphere at a radius of 5.00 cm from the sphere's center. What is the charge on the sphere
300 grams of water at 0 degrees are placed in a copper container weighing 120 grams in which 35 grams of ice (at 0 degrees also). 17 grams of steam at 100 degrees are fed in and completly condensed to water.
A car initially travelling at 25.90 m/s undergoes a constant negative acceleration of magnitude 1.60 m/s2 after it brakes are applied. How many revolutions does each tire make before the car comes to a stop, assume the car does not skid and the ti..
A shaving or makeup mirror is designed to magnify your face by a factor of 1.25 when your face is placed 18.0 cm in front of it.
