Suppose 1.0 mol of a monatomic ideal gas initially at 10 L and 337 K is heated at constant volume to 674 K, allowed to expand isothermally to its initial pressure, and finally compressed at constant pressure to its original volume, pressure, and temperature.
A.) What is the net energy entering the system (the gas) as heat during the cycle?
B.) What is the net work done by the gas during the cycle?
C.) What is the efficiency of the cycle?
When blue light of wavelength 465 nm illuminates a diffraction grating, it produces a 1st order utmost but no 2nd order maximum.
Calculate the Q-value, recoil energy of the daughter nucleus and the kinetic energy of the alpha particle in the following alpha decays
A 30.0-kg child sits on one end of a long uniform beam having a mass of 20.0 kg, and a 40-kg child sits on the other end. How long is the beam
Starting from rest, a boulder rolls down a hill with constant acceleration and travels 3.00m during the first second. how FAR does it travel during the second second
The coefficients of friction between a block of mass 0.5 kg and a surface are ?s = 0.75, What is the magnitude of the frictional force (in newtons) on the block if the block is at rest
A conducting sphere that carries a total charge of -9.1 µC is placed at the center of a conducting spherical shell that carries a total charge of +1.7 µC. Determine the charge on the outer surface of the shell
Suppose you see two main-sequence stars of the same spectral type. Star 1 is dimmer in apparent brightness than Star 2 by a factor of 100. What can you conclude? (Overlook any effects that might be caused by interstellar dust and gas.)
A barbell spins around a pivot at its center at A. The barbell consists of two small balls, each with mass 400 grams (0.4 kg), at ends of a very low mass rod of length d = .6 m. The barbell spins clockwise with angular speed 20 radians/s.
A 3.0cm × 3.0cm parallel-plate capacitor has a 2.0mm spacing. The electric field strength inside the capacitor is 1.1×105V/m
An ideal spring of negligible mass is 13.00 long when nothing is attached to it. When you hang a 3.00- weight from it, you measure its length to be 14.50 .If you wanted to store 10.0 of potential energy in this spring, what would be its total leng..
