How is everything in the natural world connected? i don't know how to explain it, .

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.

Will you chech and finish these for me, because i am stumped with them.

In a system, when potential energy decreases, then entropy also decreases. true false
