9. What is the mass of a 50 N object on the Earth? Given
g= 10 m/s2
a 5 kg
b 25 kg
C 10 kg
d 50 kg
Hel hurry

the answer is 12 as i may remember

: )

at right angles to each other

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
