Which scientist described the existence of the neutron

Clyde and Marilyn are riding a roller coaster. During which section of the track is their potential energy converted to kinetic energy?

A photon with wavelength λ = 0.0830 nm is incident on an electron that is initially at rest. if the photon scatters in the backward direction, what is the magnitude of the linear momentum of the electron just after the collision with the photon?

Two water manometers are connected to a tank of air. One leg of the manometer is open to 100kPa pressure (absolute) while the other leg is subjected to 90kPa. Find the difference in deflection between both manometers, Delta h_a - Delta h_b.

A circuit contains two 1.5 volt batteries and a bulb with a resistance of 3 ohms. Calculate the current.

In an ac induction motor, the stator produces a rotating magnetic field that induces current in the rotor windings. The rotor current generates a magnetic field in opposition to the magnetic field of the stator, thereby causing the rotor to turn. A.
