A rainbow. Dispersion is the splitting of radiation into it's different wavelengths.
Answer:
10 times
Explanation:
The weight of the person is defined as the product of mass of person and the acceleration due to gravity of that planet.
Let the gravity is g.
W = m x g .... (1)
Now the value of g depends on the mass of earth when the radius of earth is constant.
g' = 10 g
So, W' = m x g' = m x 10 g = 10 mg = 10 W (from (1)
So, the weight of the person becomes 10 times.
