Answer:

<h3>The answer is 1.92 g/cm³</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass = 2.5 g

Volume = 1.3 cm³

We have

density =  \frac{2.5}{1.3}  \\  = 1.923076...

We have the final answer as

<h3>1.92 g/cm³</h3>

Hope this helps you

When you add up (20N down) and (10N up), 
you get a sum of (10N down).

The mass of the object has no effect on the forces.


Now ... I see 5 points for the answer.

<span>A 67.0 kg crate is being raised by means of a rope. Its upward acceleration is 3.50 m/s2. What is the force exerted by the rope on the crate? 

</span>Newton's Second Law<span> of Motion states, “The force acting on an object is equal to the mass of that object times its acceleration.” We calculate as follows:
</span>
F = ma = 67.0 kg (3.50 m/s^2) = 234.5 J
