Newton’s law of universal gravitation, F=Gm1m2/r²,measures the force of gravity between two masses m1 and m2,where r is the dist

Pavel [41]

Answer:

$G=\frac{Fr^2}{m_1m_2}$

Step-by-step explanation:

Since our equation is $F=\frac{Gm_1m_2}{r^2}$ and we want to solve for G, first we divide both sides by the product $m_1m_2$ , which gives:

$\frac{F}{m_1m_2}=\frac{Gm_1m_2}{m_1m_2r^2}=\frac{G}{r^2}$

So we are left with:

$\frac{F}{m_1m_2}=\frac{G}{r^2}$

Now we multiply both sides by $r^2$ , which gives:

$\frac{Fr^2}{m_1m_2}=\frac{Gr^2}{r^2}=G$

Which gives us our final formula:

$G=\frac{Fr^2}{m_1m_2}$

18. A store sells two different kinds of rulers, plastic and wood. The receipts show that they have sold 35 total rulers today.

kvv77 [185]

Answer:

12 wooden rulers

23 plastic rulers

Step-by-step explanation:

Total rulers sold - 35

Total profit - $82

1 wooden ruler - $3

1 plastic ruler - $2

$3 x 12 = $36

$2 x 23 = $46

$46 + $36 = $82

12 + 23 = 35 rulers
