How far will an object travel in 30 seconds if it’s going at the rate of 5 meters per second?

use d = r * t for these kinds of problems.. constant speed .. is the key here zero acceleration

Explanation:

d= distance. in meters

r= rate or speed in meters per second

t = time.. in seconds

d= 30 * 5

d=150 meters

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
