10th science 1 project take weight of your five friends. Find out what their weights will be on the moon and mars
Answers
Answer:
The weight of five friends is 54,56,60,72 and 75 kg.
The weights on the Moon and Mars are given as follows:
1. Earth- 54 kg ;Moon- 8.91 kg; Mars- 20.44kg
2. Earth- 56kg ; Moon- 9.24 kg; Mars- 21.18kg
3. Earth- 60kg ; Moon- 9.9 kg; Mars- 22.69kg
4. Earth- 72 kg ; Moon- 11.88 kg; Mars- 27.23kg
5. Earth- 75 kg ; Moon- 12.37 kg ; Mars- 28.36kg
Method:
1. Moon:
Their weight on the moon= 16.5% of the weight on earth.
It is because the acceleration due to gravity on the moon is 1/6 th that of the Earth.
2. Mars:
The weight on Mars can be calculated as:
Weight( Mars): (Weight on Earth/ 9.81)×3.71
[ 9.81 m/s^2 is the acceleration due to gravity on Earth and 3.71 m/s^2 is the acceleration due to gravity on Mars.
Therefore, their weights can be calculated accordingly.
