Answer:

I. The bullet covers a longer horizontal distance on the Moon.

II. The bullet's flight duration is shorter on Earth.

Explanation:

The behavior of bullets is characterized by projectile motion, showing uniform motion in the horizontal plane and free-fall motion vertically.

Bullets drop due to gravity, and since earth's gravity is stronger, bullets descend more swiftly, leading to reduced flight time on Earth. Consequently, with shorter flight time, there is less duration for horizontal travel prior to falling, thus making the horizontal distance achieved lesser on Earth.

Answer:

I. For the Moon, the bullet travels a longer horizontal distance.

II. The bullet experiences a shorter flight time on Earth.

Explanation:

The distance covered horizontally depends on initial velocity, height, and gravitational force. Bullets possess the same initial speed and are fired from an identical height. Hence, in this scenario, the horizontal distance solely relies on gravity, which has an inverse relationship. This leads to the conclusion that less gravity results in greater horizontal distance. Gravity impedes bullet movement and influences its arrival at the ground. The increased gravity on Earth causes the bullet to hit the ground more quickly.
