No photoelectrons are emitted from a certain metallic surface when the momentum of the photons striking the surface is smaller than p0= 1.6x10^-27 kg m/s. If the surface is bombarded with photons having a momentum of 3p0, what is the maximum kinetic energy (in eV) of the emitted photoelectrons?

A thin film of soap (n = 1.35) is floating in air. If light of wavelength 600 nm is missing from the reflected light, what is the minimum thickness of the soap
A 50kg box is placed on an inclined plane making an angle of 30 degrees with the horizontal, what is the resultant force on the box
presume you had job offers from two companies that differed only in how often they produced CEOs. Would these differences affect your decision.
The fundamental physical constant of quantum mechanics, h, has played an important role in each of the three theoretical advances (those relating to the blackbody spectrum, the photoelectric effect, and the structure of the H atom).
At time a grinding wheel has an angular velocity of 22.0. It has a constant angular acceleration of 33.0 until a circuit breaker trips at time = 2.20. From then on, the wheel turns through an angle of 431 as it coasts to a stop at constant angular de..
A 50 g ball isreleased from rest 1.0 m above the bottom of the track shown in the figure . It rolls down a straight 30 degree, segment, then back up a parabolic segment whose shape is given byy=1/4x2, where x and y are in meters.
A clock has an aluminum pendulum with a period of 1.000 s at 20.7 °C. Suppose the clock is moved to a location where the average temperature is 32.2 °C. (The linear expansion coefficient for aluminum is 2.20 10-5 °C?1.)
