The system is released from rest with the cable taut. For the friction coefficients μs = 0.25 and μk = 0.20, calculate the acceleration of each body and the tension T in the cable. Neglect the small mass and friction of the pulleys.

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.

answer: option c.

explanation:

the closer the planet is to the sun, the larger the gravity
