A laser light has a wavelength of 670 nanometers and the separation between the two first order diffraction minima is 11 cm. The 8th order double slit interference maxima occurs at the same position as the 1st order diffraction minimum. The distance between the slits and the screen is two meters. Calculate the slit width and slit separation.

A mass spectrometer is used to examine the isotopes of uranium. Ions in the beam emerge from the velocity selector at a speed of 3.02 105 m/s and enter a uniform magnetic field of 0.625 T directed perpendicularly to the velocity of the ions.
A mass rests on top of the piston. The initial temperature of the system is 305 K and the pressure of the gas is held constant at 137 kPa. The temperature is now increased until the height of the piston rises from 23.4 cm to 27.0 cm. What is the f..
You are to program a robotic arm on the assembly line to move in a xy-plane. Its first displacement is; its second displacement is, of magnitude 6.51 and direction 62.7 measured in the sense from +x-axis toward -y-axis. The resultant of the two displ..
