A26-foot ladder is placed against a wall. if the top of the ladder is sliding down the wall at -2 feet per second (note that the rate is negative because the height is decreasing). at what rate is the bottom of the ladder moving away from the wall when the bottom of the ladder is 10 feet away from the wall?

moisture is lackin, and organic acids are scarce.

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
