Activity A #2 - What is the speed of the toy car when set at Hill 1 - 60 cm, Hill 2 - 50 cm, Hill 3 - 20 cm (just type the number and unit, ex cm/s and round to nearest tenth) *

the answer is 3.1 his answer is wrong mines is right

3.2x10^7

this could be newton#'s law of cooling. the cooling curve is exponential

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
