What did classical physics predict about electron flow as a result of light shining on a metal surface? a. light above a certain frequency would be needed to cause electrons to flow. b.the higher the frequency of light, the more electrons would flow. c.the more light shining on the metal, the more electrons would flow. d.the lower the frequency of light, the more electrons would flow.

it may be wrong but i think its a

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.

b.transmitters send radio waves, and receivers capture radio waves.
