During a football workout, two linemen are pushing the coach on the sled. The combined mass of the sled and the coach is 349.0 kg. The coefficient of friction between the sled and the grass is 0.860. The sled accelerates at a rate of 0.670 m/s/s. Determine the force applied to the sled by the linemen in newtons. Round to a whole number. (Use g=9.81 m/s2.

b) 10 minutes

girls stopped for 10 minutes.

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
