Final answer:
The weight of an object is the product of its mass and the gravitational acceleration of the celestial body it is on, with mass being constant and weight varying with gravity.
Step-by-step explanation:
The question involves the calculation of weight and mass of objects on different celestial bodies, Earth and Mars. The weight can be calculated using the formula weight = mass × gravity. The mass of an object remains constant regardless of the celestial body it is on, because mass is an intrinsic property of the object.
- A 60kg person on Earth has a weight of 600 N (weight = 60 kg × 10 m/s²)
- A 5 kg brick on Mars has a weight of 19.15 N (weight = 5 kg × 3.83 m/s²)
- A 20 N purse on Mars implies a mass of 5.22 kg (mass = 20 N / 3.83 m/s²)
- Britney Spears has a mass of 57 kg both on Earth and Mars. Her weight on Earth is 570 N (weight = 57 kg × 10 m/s²) and on Mars it is 216.51 N (weight = 57 kg × 3.83 m/s²)
