an x ray photo of wavelength 10.0pm is scattered through 100° by an electron. what is the kinetic energy of the recoiling electron

When using two-wire cable to feed a 240-v appliance that does not require a neutral wire, you should a. mark both ends of the white wire green. b. use the cable as is. c. use only the black wire. d. mark both ends and any exposed area of the white wire black.

Wavelength, frequency, and energy are related. what happens to a wave as it’s wavelength gets shorter?
