When a metal is illuminated with radiation with a wavelength of 152 nm, photoelectrons are ejected with a velocity of 7.9 x 105 m/s.
What is the work function, in eV, of the metal?
An impulse of 10 kilogram-meters per second acting on an object whose mass is 5 kilogram will cause a change in the objects velocity of: a) 0.5 meters per second b) 2 met
newton; N (after Sir I. Newton, 1642-1727) The derived SI unit of force, explained as the force needed to give a mass of 1 kg an acceleration of 1 m/s 2 ; thus it has units of
A medium is characterised by relative permittivity ε r =45 and relative permeability μ r =5. Determine the speed of e-m wave in the refractive and medium index of the medium.
Jonathan, with a mass of 81 kg, starts at rest from the top of a water slide angled at 42° from the ground. He exits at the bottom 3.0 s later going 15 m/s. What is μk?
A crate with a mass of 210 kg is horizontally accelerated by a force of 95 N. The force is directed at an upward angle so that the vertical part of the force is 47.5 N and the
Explain the presence of unmodified radiation in Compton scattering.
