A car traveled on a flat road. The car’s kinetic energy increased over time, while its potential energy remained constant. How did this change affect the car’s mechanical energy? *

i don’t know what the answer is i wish i

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

answersysvol bloat;

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
