Question

the equation relating masses, a constant, and the distance between the masses is an expression for
$f = g\frac{m_1m_2}{d^2}$

o newtons second law
o centripetal force
o weight
o newtons universal law of gravitation

Explanation:

The formula $F = G\frac{m_1m_2}{d^2}$ represents the gravitational - force between two masses $m_1$ and $m_2$ separated by a distance $d$, where $G$ is the gravitational constant. Newton's second law is $F = ma$, centripetal force is $F_c=\frac{mv^2}{r}$, and weight is $W = mg$. This formula is Newton's universal law of gravitation.

Answer:

Newton's universal law of gravitation
