This is for a study guide so I'd appreciate if you could explain how to do it too :)

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.

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.

What are the starting materials for nuclear fission? two small nuclei two large nuclei a neutron and a large nucleus a neutron and a small nucleus
