Para cada rapidez en la figura 2.9, ¿cuáles son (a) la distancia recorrida entre t = 0 y t = 1.50s y (b) la relación entre la distancia recorrida y el intervalo de tiempo correspondiente? Para cada rapidez, ¿cuáles son (c) el intervalo de tiempo requerido para pasar de x = 2.00 m a x = 3.50 m y (d) el cociente entre la distancia recorrida y el intervalo de tiempo correspondiente?

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.

which three statements are true about all alloys?

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
