Answer:
4 ft/s^2
Explanation:
If the velocity is 8ft/s after 2s then to find the acceleration you would use the formula:

sooooooooo

Yes energy makes things move
227kj Because The first thing to do here is to calculate the energy of a single photon of wavelength equal to
527 nm
, then use Avogadro's number to scale this up to the energy of a mole of such photons.
I think it's interference? Sorry if I'm incorrect.
