Question: A hydrogen atom makes a transition from the n = 3 state to the ground state and emits a single photon of light in the process. The photon then strikes a piece of silicon, which has a photoelectric work function of 4.8 eV. Calculate the energy of emitted photon. (Express your answer to four significant figures.) Find the maximum possible kinetic energy of the photoelectron. (Express your answer to three significant figures.)
Three objects are held in place on three corners of a square, with sides of length 1.10 m. Find the electric potential at the fourth corner of the square
An electron confined in a one-dimensional box emits a 400nm photon in a quantum jump from n=1 to n=2. What is the length (L) of the box in nm
A carbon is 12 times heavier than a hydrogen atom. If methane (CH4) is chemically decomposed, what is the ratio of the weights of the resulting carbon and hydrogen?

Two identical 1.3-kg blocks are connected by a massless string over a frictionless pulley of radius R = 15.000 cm and rotational inertia I = 0.004 kg m2, find the magnitude of the linear acceleration of the two blocks
Energy is transferred in solids by conduction, which means that. Heat travels in both directions. Heat travels from the cooler object to the hotter object. Heat does not travel between objects of different temperatures.
