Which condition must be met in order for an equation to be balanced? cu
The elements in the reactants are the same as the elements in the products.
There are fewer elements in the reactants than there are in the products.
O The number of atoms in the reactants is greater than the number of atoms in the products.
The number of atoms in the reactants equals the number of atoms in the products.

490 n

f=125n a=2.5m/s2

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

can somebody give me the answer so i can graduate
