If mass of the planet is 10% less than that of the earth and radius of the planet is 20%
greater than that of the earth then the weight
of 40kg person on that planet is

25kg

Explanation:

The formula for acceleration due to gravity is:

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.

Multiplying this by the weight of the person on Earth of 40kg, you get 0.625*40=25kg.

Hope this helps!

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
