Q. A student has set up the the He-Ne laser (632.8 nm) and a diffraction grating with unknown slit spacing as shown in Figure 9.5. When the diffraction plate is 44.0 cm from the diffraction scale, the first order spots are measured at 19.8 cm either side of the optical axis. What is the line spacing of the diffraction grating in lines per centimeter?
Q. A cylinder of gas at room temperature (20°C) has a pressure p1. To what temperature in degrees Celsius would the temperature have to be increased for the pressure to be 2.7p1?
Two physical pendulums ( not simple pendulum) are made from sticks that are suspended from the ceiling at one end. The sticks are uniform and are identical in all respects, except one is made of wood (mass = 0.17 kg )and the other of metal (mass =..

The horizontal component Fx is shown by the histogram below as function of position along x-axis. There is also a kinetic frictional force of 0.50 N between mass and surface.
What is the magnitude of the magnetic field. Evaluate this to the tension as the boat is raised and held at rest so the angle becomes 25 degrees.
If a ball is thrown upwards at 20 ft/sec, the height h after t seconds is given by h = -16t^2 + 20t. How many seconds does it take for the ball to reach its greatest height, and what is this height.
A ski jumper has 1.2 ´ 10 J of potential energy at the top of the ski jump. The friction on the jump slope is small, but not negligible. What can you end about the ski jumper's kinetic energy at the bottom of the jump.
