What does Newton’s law of universal gravitation say about the distance between objects? s=been 3 hours still waiting...

andrew-mc [135]

Answer:

Gravitational Force is inversely proportional to the square of distance between the objects

$F\alpha \frac{1}{d^{2}}$

Explanation:

This means if distance is tripled(3 times), then Force reduced to 1/9(square of distance )

If d = 3 ,

$F\alpha \frac{1}{3^{2}}$

$F\alpha \frac{1}{9}$

Then , F reduced to 1/9

Balance the following chemical equation, then answer the following question.

julsineya [31]

Molar mass:

O2 = 31.99 g/mol
C8H18 = 144.22 g/mol

2 C8H18(g) + 25 O2(g) = 16 CO2(g) + 18 H2O(g)

2 x 144.22 g --------------- 25 x 31.99 g
10.0 g ----------------------?? ( mass of O2)

10.0 x 25 x 31.99 / 2 x 144.22 =

7997.5 / 288.44 => 27.72 g of O2

hope this helps!
