You have probably never noticed time dilation effects in everyday life. Do some calculations to see why this is.
(a) Calculate the speed that a friend would have to move with respect to you so that your measured time intervals are 1.00% larger than hers. That is, for each 100 elapsed seconds on her wristwatch, 101 seconds elapse on yours.
(b) How many times larger is the speed you just calculated than the speed of an orbiting space shuttle, 8.00×10^3 m/s?
A 750 g aluminum pan is removed from the stove and plunged into a sink filled with 10.0 liters of water at 20.0 ° C. What was the original temperature of the pan

2 moles of an ideal gas is allowed to expand from 0.002 m^3 to 0.02 m^3 while the pressure is held at 325000 pascals. Determine the net heat flow in or out of the system
what is the volume of an iron atom. What is the ratio of the mass density of girder A to the mass density of girder B.
How much work is needed to move it at constant speed.
The barrel has a length of 0.60 m and an opening whose radius is 2.8 10-3 m. A bullet (mass = 2.7 10-3 kg) has a speed of 380 m/s after passing through this barrel. Ignore friction and examine the average pressure of the expanding gas.
What is the minimum coefficient of friction between tires and road that will allow cars to negotiate the turn without sliding off the road.
A disk of radius R has a uniform surface charge σ on one side. A circular hole of radius R/2 is now cut in the center of the disk. What is the electric field at the center of the hole
When a 700? resistor is connected across an AC power supply, the resistor dissipates energy at a rate of 15.0W. Find the maximum current through the resistor
