At a constant velocity, you are pulling a 10kg object with. force p. how much work is done by p to move 87cm? assume kinetic frictional coefficient = 0.26.

A150 w lamp emits light of wavelength 590 nm uniformly in all directions. what is the photon flux (photons per unit area per unit time) on a small screen at a distance 2.3 m from the lamp? assume the photons are uniformly distributed over the surface of a sphere of radius 2.3 m.

Light that is polarized along the vertical direction is incident on a sheet of polarizing material. only 96% of the intensity of the light passes through the sheet and strikes a second sheet of polarizing material. no light passes through the second sheet. what angle does the transmission axis of the second sheet make with the vertical?

Which of the following bonds would be most polar? a. c-i b. c-br c. c-cl d. c-f e. c-o
