Answer :
The weight of an object on Earth is directly proportional to its mass. Using a proportion, we can calculate that a 195-pound astronaut would weigh 78 pounds on Mars.
The weight of an object on Earth is directly proportional to its mass. If a 25-pound object on Earth weighs 10 pounds on Mars, we can set up a proportion to find out how much a 195-pound astronaut would weigh on Mars:
25 pounds on Earth / 10 pounds on Mars = 195 pounds on Earth / x pounds on Mars
Cross-multiplying and solving for x, we get:
x = (10 pounds on Mars * 195 pounds on Earth) / 25 pounds on Earth
x = 78 pounds on Mars
Therefore, a 195-pound astronaut would weigh 78 pounds on Mars.
