Aspacecraft is flying away from the moon toward the earth. the moons gravitational pull on the spacecraft

a. repel the spacecraft

b. decrease

c. increase

d. remain the same

B. Decrease

Explanation: When an spacecraft is flying away from the moon, the moons gravitational pull on the spacecraft will decrease because gravitational force is directly proportional to the mass of the moon and mass of the spacecraft while inversely proportional to the square of the distance between them. So as the spacecraft moves away from the moon, gravitational pull will decrease.

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.
