A 5.0kg kid comes down a slide from a height of 3.0 meters. At the bottom, he has a speed of 6.3m/s. The slide is 5.0 meters long. What is the frictional force acting on the kid

there are no atoms

answercollision;

it is b. absorbs thermal energy

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
