To find the person's weight on Earth based on the weights given for the moon, Mars, and Jupiter, we first need to understand that weight is the product of mass and gravitational acceleration. The weight on the moon is 12 kg, which corresponds to a gravitational acceleration of about 1.62 N/kg. This implies a mass of approximately 7.41 kg (12 kg / 1.62 N/kg). On Earth, with a gravitational acceleration of 9.81 N/kg, this mass would weigh about 72.7 N (7.41 kg * 9.81 N/kg). The weight on Jupiter is given as 189.982 kg, which corresponds to a gravitational acceleration of about 24.79 N/kg, leading to a mass of approximately 7.66 kg (189.982 kg / 24.79 N/kg). Therefore, the person's weight on Earth is approximately 75.18 N (7.66 kg * 9.81 N/kg). Thus, the person's weight on Earth is around 75.18 N or approximately 75 kg.
