1,If a person's mass is 75kg on earth.what Will be his mass on the moon? 2,Give a reason for your answer above (1)?

1. The person's mass on the moon will still be 75kg.

2. The reason for this is that mass is a fundamental property of an object and does not change based on the location or gravitational field. The moon has a weaker gravitational pull compared to Earth, but it does not affect the mass of an object. Therefore, the person's mass remains the same on the moon as it is on Earth.
