Question 3 of 5
rusak2 [61]

Answer:

A. More mass

C. Shorter distance between them

Explanation:

The two characteristics of a body experiencing greater gravitational force are that they have mass and a shorter distance between them.

This is conformity with Newton's law of universal gravitation.

The law states that "every object attracts one another with a force that is directly proportional to their masses and inversely proportional to the square of the distance between them".

This law implies that the more the mass of two bodies, the more the gravitational force of attraction. And that the shorter the square of the distance between them, the more the attraction.

I am very confused, our teacher didn’t properly teach us this. How do you do it?
Fudgin [204]

Answer:

You multiply the 3 numbers together to get your volume, in this case it would be 4058.488 cm^3 (cm cubed)

so

V: 4058.488cm^3 ( round up to 4058.5 for convenience)

M: 27579

D: ?

So we divide mass by the volume to get density, which is

27579 / 4058.5 = ~6.79536 (can round up to 7 or 6.8)

This graph can help a lot, so maybe try and memorize it, hope I helped.

Find the mass of an object with a density of 2.01g/mL and a volume of 3.77mL
oee [108]

Answer:

<h2>7.58 g</h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question we have

mass = 2.01 × 3.77 = 7.5777

We have the final answer as

<h3>7.58 g</h3>

Hope this helps you
