, A 50 kg astronaut weighs 490 N. What would she way if she landed on Jupiter‘s moon Callisto what fraction is this of her weight on earth?

The fraction of the weight of the astronaut on Callisto to the weight on Earth is 0.126.

Explanation:

From Newton's Law of Motion, the weight (), measured in newtons, of an object is defined by this expression:

(1)

Where:

- Mass, measured in kilograms.

- Gravitational acceleration, measured in meters per square second.

The gravitational acceleration in Callisto is 1.236 meters per square second.

If we know that and , then the weight of the astronaut in Callisto is:

And the fraction is:

The fraction of the weight of the astronaut on Callisto to the weight on Earth is 0.126.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
