1. A blue laser has a wavelength of 450 nm, a green laser has a wavelength of 560 nm, a red laser has a wavelength of 660 nm. Put these in order from largest to smallest amount of energy.
2. Radio waves have wavelengths of 100m or more. Microwaves have wavelengths between 0.001m and 1m. Why do you think microwaves can cook you food but radio qaves can't? Be as detailed as possible.
(PLEASE HELP IM DESPERATE)

Acatapult is tested by roman legionnaires. they tabulate the results in a papyrus and 2000 years later the archaeological team reads (distances translated into modern units): range = 0.4 km; angle of launch = π/5 rad; landing height = launch height. what is the initial velocity of launch of the boulders if air resistance is negligible?

Aboxcar traveling at 12 m/s approaches a string of 5 identical boxcars sitting stationary on the track. the moving boxcar collides and links with the stationary cars and they all move off together along the track. what is the final speed of the cars immediately after the collision? (you may take the mass of each boxcar to be 18,537 kg.)
