Explain the difference between a photon of red light and one of violet light in terms of energy, frequency, and wavelength. What scientist won the Nobel Prize for explaining the photoelectric effect? Name another theory for which that scientist is famous.
When 5.30* 10^5 J of heat is added to a gas enclosed cylinder fitted with a light frictionless piston maintained at atmospheric pressure, estimate the work done by the gas
Two stationary point charges of 5.00nC and 2.00nC are separated by a distance of 60.0 cm. What is the electric potential energy of the electron
Find through what potential difference (Delta V) must electrons be accelerated ((From rest) so that they will have the same wavelength as an X ray of wavelength 0.160 nm
Vector addition of: 1.47 N @ 30 degrees, 1.47 N @ 120 degrees, and 1.47 N @ 180 degrees. Show work on how to find the resultant vector and angle of resultant vector
A 528 Hz sound wave travels through a substance. The wavelength of the sound wave is measured to be 1.9 meters. What is the speed of sound in the substance
The heating element of a simple heater consists of a 1.9-m-long, 0.65-mm-diameter nichrome wire. What is the wire's resistance when it is hot
A charge q is located at the tip of a hollow cone (such as an ice cream cone without the ice cream) with surface charge density σ . The slant height of the cone is L, and the half-angle at the vertex is θ . What can you say about the force on the ..
A cord is wrapped around the rim of a solid uniform wheel 0.300 {\rm m} in radius and of mass 9.00 {\rm kg}. A stable horizontal pull of 42.0 {\rm N} to the right is exerted on the cord, pulling it off tangentially from the wheel.
let c 3.10m 15 degrees above the x-axis and d 23.3m 44 degrees to the right of the negative y-axis. find the magnitude
A spherical raindrop of mass 0.00942 g and radius 1.31 mm falls from a cloud that is at a height of 1115 m above the ground. What would be the raindrop's speed just before landing on the ground if there were no drag force
An experiment is designed to measure the partition coefficient, K, associated with the transfer of a pharmaceutical product through a polymer material. The partition coefficient is defined as the ratio of the densities of the species of interest (..
In a photocell, ultraviolet light provides sufficient energy to some electrons in barium metal to eject them from the surface at high speed. See Fig. 23-36. To gauge the maximum energy of the electrons, another plate above the barium surface is kept ..
