Aperson standing on the surface of the earth has a weight of 650 n. what is its weight at a distance of two earth radii from the surface? if the person is at a distance of two earth radii from the surface, he/she is at a distance of three earth radii from the earth’s center. since we have an inverse square law, three times the distance means 1/9th of the weight.

72.22 N

Explanation:

F = weight

m = mass of body

M = mass of earth

R = radius of earth

G = universal constant of gravitation

F_1= 650 N

F_1 = GMm/R^2

two earth radius above the surface of the earth:

F_2=  GMm/(3R)^2=  GMm/9R^2= F_1/9= 650/9

=72.22 N

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."

the answer to this is proletariats.

hope this : )
