gregori [183]4 years ago
4 0

Answer:

10%

Explanation:

Efficiency = work done / energy used

e = (10 m × 100 N) / (10,000 J)

e = 0.1

The efficiency is 0.1, or 10%.

All the following statements are true. Which one is most important in explaining the tremendous tidal heating that occurs on Io?
SVEN [57.7K]

Answer:

  • <u>Option:(D)-</u>

<em>"Io orbits Jupiter on an elliptical orbit, due to orbital resonances with other satellites."</em>

Explanation:

  • <u>"Io" moon of Jupiter:</u>

The Io is one of the four moons of Jupiter, as it rotates around the planet in an elliptical orbit, due to orbital resonance with other satellites. As due to the rotational motion of the moon, while orbiting the planet and having a large amount of gravitational pull on them there is a net amount of heat between the two heavenly bodies in the solar system. As the moon is very small in size as compared to giant celestial body, the crust of the moon is distorted by the unequal force of the gravity on each of its side by the planet causing a distortion of the moon's over all shape.
