An electron and a proton are initially very far apart (effectively an infinite distance apart). They are then brought together to form a hydrogen atom, in which the electron orbits the proton at an
An 55.0-N crate of apples sits at rest on a ramp that runs from the ground to the bed of a truck. The ramp is inclined at 18.0° to the ground. (a) What is the normal force exerted on the crate
Assume that the star is a perfect blackbody, and that the average temperature of the rest of the universe is 2.73 K. Do not consider thermal radiation absorbed by the star from the rest of the unive
An ideal gas is taken through a Carnot cycle. The isothermal expansion occurs at 250 °C, and the isothemal compression occurs at 50 °C. If the heat absorbed during the isothermal expansion i
Charges of +8.5x10^-7 C each are located at three of the corners of a square that is 1m on each side. A charge of -1.5x10^-6 C is located at the bottom left corner. What is the electric field at the

As a helicopter carrying a crate takes off, its vertical position (as well as the crate's) is given as: y(t) = At^3 where A is a constant and t is time with t = 0 corresponding to when it leaves the
Suppose our experimenter repeats his experiment on a planet more massive than Earth, where the acceleration due to gravity is . When he releases the ball from chin height without giving it a push, h
What object defines the Other Frame? What object is the object whose velocity we want to determine in both frames? Calculate the relative velocity of the suspect's car and the patrol car.
In a region of space there is an electric field 'E' that is in the z-direction and that has magnitude E = (747 N/(C*m))x. Find the flux for this field through a square in the xy-plane at z = 0 and w
A charged paint is spread in a very thin uniform layer over the surface of a plastic sphere of diameter 12.5 cm, giving it a charge of -10.0 µC. (a) Find the magnitude of the electric field ju
An expandable cylinder filled with neon, a monatomic ideal gas, initially has a volume of 3.0 L at 1.5 atm and 20 oC. Thermal energy is slowly added to the gas until the volume is 11.0 L but the pre
Call S(m) the entropy of the coffee beans when they are distributed between m cups. What is ?S = S(25) - S(5), the difference in entropy between when there are 25 cups and when there are 5 cups? Giv
