The gravitational force between two objects is 100 n
if the mass of each object is doubled, what is the
gravitational force between the objects at the same
distance?
a: 25 n
b: 50 n
c: 200 n
d: 0400 n

D

Explanation:

The general equation for this is

F = G*m1*m2/r^2

If the distance (r) remains the same and m1 and m2 are both doubled, then the equation becomes

F1 = G * (2m1)(2m2)/r^2

F1 = 4 [G * m1 * m2)/r^2 ]

So F1 is 4 times as large as the initial Force (F)

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
