Hey cylinder with a mass of 12 g has a radius measuring 2 cm and a height of 6 cm. what is the density?

do you have a formula possibly

elctricity and magnet is conversion to it

answer a fan shaped mass of sediment deposited at the base of a mountain front do to an abrupt change in stream gradient;

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
