A record is dropped vertically onto a freely rotating turntable. Frictional forces act to bring the record and turntable to a common angular speed. If the rotational inertia of the record is 0,50 fimes that of the turntable, what percentage of the initial kinetic energy is lost? Select one: O a. 66% O b. 33% O c. 75% O d. 18% O e. 46%

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).

explanation:

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.

i think the answer is a and b

i wish you luck
