Sam is about to drop a golf ball from his hand. As the ball falls, its
energy will decrease and its
energy will increase.

Options for the first blank
- kinetic
- elastic potential
- gravitational potential

Options for the second blank
-kinetic
- elastic potential
-gravitational potential

i think the answer would be b

c. magnitude and direction

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
