W A diffraction grating of width 4.00 cm has been ruled
with 3 000 grooves/cm. (a) What is the resolving power of
this grating in the first three orders? (b) If two monochromatic waves incident on this grating have a mean
wavelength of 400 nm, what is their wavelength separation
if they are just resolved in the third order?

hail is a solid form of precipitation composed of large, layered ice particles called pellets that often have spherical shapes. this phenomenon occurs during thunderstorms in the could type known as cumulus

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
