You are driving home from school steadily at 102.3 km/hr for 130 km. It then begins to rain and you slow to 63 km/hr instantly. You arrive home after driving 3 hours and 20 minutes. (a) How far is your hometown from school?

the force required to move the cart is divided by three or 33.33 n.

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
