If the energy of a photon exceeds the work function of a metal, the photon is capable of ejecting an electron from the material. The energy of the electron is equal to that of the photon minus the work function. Calculate the energy of the electron emitted following irradiation of Cs (work function

Who was the first scientist to measure speed as distance over time?

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.

An alien spaceship is 500 m above the ground and moving at a constant velocity of 150 m/s upwards. how high above the ground is the ship after 5 seconds?
