A rock is dropped from a bridge, and the distance it travels and the speed at which it is falling are measured every second until it hits the water. The data are shown in the chart below. Make two graphs of the data:
a distance-time graph and
a velocity-time graph.
Use your graphs to answer the questions below.

where are the vectors ?

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.

did yall get answers for this yet

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
