Detailed explanation-1: -Solution : In a satellite the astronaut feels weightlessness and therefore weight becomes zero but mass remains unchanged.
Detailed explanation-2: -Answer and Explanation: There will be no difference in the mass of the astronaut on Earth and Moon. Mass is a constant value, but the weight of the person vary with location on the planet . Weight is the downward force acting on a person or any body due to gravity.
Detailed explanation-3: -In space, astronauts and their spaceship still have mass and are still acted upon by Earth’s gravity. In this sense, they still have weight, even though Earth’s gravitational force is smaller in orbit than it is on Earth’s surface (Box 1). However, they do not feel their weight because nothing is pushing back on them.
Detailed explanation-4: -Step 1: Given data. Mass of the astronaut, Mass remains constant throughout the universe. Acceleration due to gravity on earth, 8 m / s 2. Step 2: Finding the weight of the astronaut on earth. W a e = m g = 80 × 9 . 8 = 784 N. Thus, the weight of the astronaut is . Suggest Corrections.
