Mass and Motion A cat with a mass of 5 kg is sitting on a skateboard.
A rat with a mass of 0.5 kg is sitting on an identical
skateboard.
2. If you apply the same force to push each
skateboard, will the cat or the rat accelerate the
fastest? Explain.
Type your answer here.

Explanation:

Force is same in both situation .Then let force be F

Mass of cat =5kg(m1)

Mass of rat=0.5kg(m2)

f=ma

a=f/m

f=a1/5. ... (1) f=a2/0.5 (2)

from 1st and 2nd

a1/a2=10/1

cat accelerate fast

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
