an Empty airplane has a mass of 30400 kg and a takeoff acceleration of 1.20 metre per second square what is the net force accelerating the plane

Net force will be 36,480 N

Explanation:

As force equation is F=ma, here F =force in newton, m, mass in kg, a =acceleration in metre per second.

so F = 30400 kg * 1.20 metre per second

which will be F= 36480 Newtons

F=36480 N

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
