the jackson prairie is a temperate grassland region in mississippi, spread over an area of fertile soil. what could be a reason why this grassland is disappearing rapidly?
a) changing into farmlands
b) encroachment by the forest
c) grazing by herds of buffalo
d) occasional outbreaks of fire

explanation:

areas w steep slopes, west coast, rocky mountains, and appalachian mountains

answercollision;

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
