According to the photon energy formula, tripling the frequency of the radiation from a monochromatic source will change the energy content of the individually radiated photons by what factor?

By a factor of 3

Explanation:

In the photon energy formula , frequency and the energy content have a direct relationship. This means anything that is done to one of the parameters is the same that will be done to the other to have a balance.

In this equation: Energy=plank’s constant * frequency.

Energy is directly proportional to frequency.

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

god i hope this !
