Requirements: Full answer
The Earth’s magnetic field around the equator is 0.25 μT [north]. (Note: μ is the SI prefix for × 10−6). What velocity should a proton (with charge 1.60 × 10−19 C and mass 1.67 × 10−27 kg) have to experience a magnetic force equal in magnitude but opposite in direction to gravity?
An airplane is flying around the world with a cesium clock onboard. Referring to this clock, describe a frame of reference that would observe proper time, and a frame of reference that would observe relativistic time. Include an explanation of how you know.
A photon with a wavelength of 525 nm strikes an electron, which then moves with a speed of 2.00×105 m/s. What is the new wavelength of the photon that is scattered by the Compton effect?
What is the de Broglie wavelength of a 16,534 kg bus travelling at 39 km/h? Will this bus experience diffraction in everyday conditions?
A 1.0000×10-11 m wavelength x-ray photon strikes an atom in an example of Compton scattering. The scattered photon has a wavelength of 1.0301×10-11 m at an angle of 29° from the initial direction. What is the velocity of the emitted electron?
In the standard model, a strange quark is described as having a mass of about 96 MeV/c2. Explain why this is a valid unit of measuring mass, and convert it to kilograms.
