Suppose a single photon strikes an electron in some material, knocking it out of its atom. Which of the following statements are true concerning the scattered photon? a. The scattered photon has greater energy than the incident photon.
b. The scattered photon has a shorter wavelength than the incident photon.
c. The scattered photon has a longer wavelength than the incident photon.
d. The scattered photon has less energy than the incident photon.

the answer to this question is 60 n

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.

it has to be b, about 97 percent.

the answer to this is proletariats.

hope this : )
