A physics instructor wants to project a spectrum of visible-light colors from 400 nm to 700 nm as part of a classroom demonstration. She shines a beam of white light through a diffraction grating that has 700 lines per mm, projecting a pattern on a screen 2.9 m behind the grating. How much distance separates the end of the m = 1 spectrum and the start of the m = 2 spectrum?

he kicked it 10 feet straight up into the air? i think this works.

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d

grav forces affect all objects magnetic forces affect magnetic objects and electric currents

i think its c if i'm wrong
