A net force of 9.0n east is used to push a 2.0kg object. What is the acceleration of the object? Put your Answer and Solution.​

You know that force and acceleration are connected through mass, or:

F

=

m

a

Here you have:

10

=

5

m

so that

m

=

10

5

=

2

k

g

;

Then if you have

a

=

8

m

s

2

you get:

F

=

2

⋅

8

=

16

newton's first law of motion

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
