What is newton's second law of motion?

forces are balanced when they are equal and opposite.

an object at rest or in motion will remain at rest or in motion unless acted upon by an unbalanced force.

the smaller the mass of an object, the greater the acceleration of that object when a force is applied.

the greater the force applied, the greater the acceleration.
every reaction is equal to the force applied.

d. air pressure decreases as altitude increases.

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
