Compton effect (A.H. Compton; 1923)
An effect which demonstrates that photons (the quantum of electromagnetic radiation) contains momentum. At a stationary particle, a photon fired such as an electron, will impart momentum to the electron and, as its energy has been reduced, will experience a corresponding falling in frequency.
A boat is traveling along a circular path having a radius of 20 m. Determine the magnitude of the boats acceleration if at a given instant the boats speed is v = 5 m/s and the rate
