con 2 camiones cuyas capasidades de carga son de 3 y 4 toneladas, se hisieron en total 23 viajes para transportar 80 toneladas de madera.¿ cuántos viajes realizó cada camión ? DATOS: X=cantidad de viajes del primer camión Y=Cantidad de viajes del segundo camión​

the components of a vector are the parts of the vectors that are to each other.

b perpendicular

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
