Three charges, q1, q2, and q3, are located at the corners of an equilateral triangle with side length of 1.11 m. Find the work done in each of the following cases:
A boat moves through the water with two forces acting on it. One is a 1,700-N forward push by the water on the propeller, and the other is an 1,300-N resistive force due to the water around the bow.
For 140 keV gamma rays, the mass attenuation coefficients for hydrogen and oxygen are 0.26 and 0.14 cm^2/g, respectively. What is the mean free path in water at this energy?
An alien spaceship traveling at a constant velocity of 1/3 in the +X direction passes the earth (call this event A) at time t=0.
