Force p is directed from point a(3,3,2) towards point b(7-3,12) and has a magnitude of 60n while force vector q- 60i+20j- 50k and force vector f- fi+fj+f. k. forces p. o and far concurrent. if the three forces are in equilibrium a) express force p in vector fonn (10 points) b) solve for force f (10 points) c) find the angle between forces f and p.

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
