They would fall with the same acceleration
When the iron bar is placed within the coils of a solenoid it then becomes a magnet.
Answer:
the similarity is that hands are applied and force
Answer:
25kg
Explanation:
The formula for acceleration due to gravity is:
![g=\dfrac{GM}{r^2}](https://tex.z-dn.net/?f=g%3D%5Cdfrac%7BGM%7D%7Br%5E2%7D)
Here, G represents a constant and M represents the mass of the object. We don't need to know the actual values to solve this, then: We can just multiply by the amount they are multiplied relative to earth.
![g=\dfrac{G(0.9M)}{(1.2r)^2}=0.625g](https://tex.z-dn.net/?f=g%3D%5Cdfrac%7BG%280.9M%29%7D%7B%281.2r%29%5E2%7D%3D0.625g)
Multiplying this by the weight of the person on Earth of 40kg, you get 0.625*40=25kg.
Hope this helps!
