Question 4 1 pts Which experiment best demonstrates the particle nature of light? Young's Double-Slit Experiment Photelectric Effect Heisenberg Trials Milikan's Oil-Drop Experiment Stern-Gerlach Experiment Question 5 1 pts An electron and a proton are traveling at the same speed in the same direction.

A(n) 14-kg particle has energy 92,725 kg (2. Calculate gamma (y). Question 16 1 pts A particle has y=2,258. Calculate c-v in m/s. (I would have asked for 1 - v/c, making the answer dimensionless, but the system doesn't seem to take numbers that small. Gamma is chosen to make the particle extremely close to the speed of light.) If your calculator gives problems, you might want to solve the appropriate equation for c-vor c(1- v/c) and use an approximation....
Question 17 1 pts Calculate the minimum wavelength of light (in nm) able to eject an electron from Platinum, = 6.35 eV. (1 eV = 1.6022x10-19 J) O none of the answers listed is correct O 1.95 nm 1950 nm 195 nm 200 nm
What is the de Broglie wavelength (in meters) of a neutron traveling at a speed of 0.92 c? Since the neutron's speed is close to the speed of light (c), Special Relativity must be used when calculating the linear momentum (p). The mass of the neutron is 1.675 x 10-27 kg. Suppose that an alpha particle (mαα = 6.646 x 10-27 kg) has a kinetic energy of 75 keV. What is the alpha particle's speed (v) (in terms of "c")?...
