Use equations 7 and 8 to determine the angle θ (in degrees) if the two positions of the first order spectral line are 34.3 cm and 65.7 cm. assume the distance from the diffraction grating to the slit is 55 cm.

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.

this is poiselle's equation from fluid mechanic in physics. mech eng
