A city bus accelerates away from a bus stop at the acceleration shown. At the next stop, a tourist boards the bus with 1,000-kg of recording equipment, and when the bus driver starts going again, he notices he has to press harder on the gas pedal to maintain the same acceleration.

12000j is work done

technology is the application of the knowledge gained by science.

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
