Question

Q3. Amna is an astronaut. She measured her body mass using a bathroom scale. See the reading on the scale and note it down using the correct units. i. Body mass:- ? Unit:- ? ii. What is Amna’s weight on Earth? Your weight is a measure of the amount of gravity exerted on your body by the planet Earth. If you travel to a different planet or celestial body, such as the moon, your weight changes if the gravity is different. Because the moon has about one-sixth of the gravity that Earth does, you'd weigh less standing on it. Comparing Objects' Gravity Gravity is based on an object's mass and your distance from the center. When you're on the surface of a planet, you can use the planet's radius to calculate your distance from the center. If you compare the mass of the moon to the earth's, you will find that the moon's mass is 0.0123 of the earth. The moon's radius is 0.273 of the Earth's. To see what the moon's gravity is compared to the earth, divide the ratio of the masses by the ratio of the radii squared. x = (ratio of masses)/(ratio of radii)^2 = 0.0123/(0.273)^2. iii. A second astronaut has a weight of 600N on Earth. What would be his body mass on Earth?
