If Punch Taut weighs 236 lb on Earth, what would his weight be on a planet where he weighs 118 lb?

To determine why the answer is D, it's essential to understand how weight is related to gravitational force. An object's weight is influenced by the gravitational pull of the celestial body it's on. On Earth, Punch Taut weighs 236 pounds, which corresponds to the gravitational acceleration of approximately 9.81 m/s².

On another planet where Punch Taut weighs 118 pounds, this indicates that the gravitational force exerted on him is different than that on Earth. The key factor here is that weight is directly proportional to the gravitational strength of the planet.

If Punch Taut weighs 118 pounds on this new planet, the gravitational acceleration must be lower than on Earth, reflecting a planet where the gravitational influence allows an object to weigh less. The name associated with this planet, Pentune, thus becomes associated with this reduced gravitational force.

Analyzing the options through contextual reasoning supports that Pentune is indeed a planet where the weight of Punch Taut aligns with a specific gravitational characteristic—specifically, one that is significantly less than that of Earth, allowing us to conclude that his weight of 118 pounds reflects that new environment's gravity appropriately.
