often have one star that is brighter than the other

Explanation:

A binary star system is a star system made up of mostly two stars that moves round their common fixed center.

The two orbiting stars are gravitationally bonded to one another and they move round each other.

Most binary stars might appear wobble. One of the stars often appears brighter than the other.

A pencil has a density of .655 g/ml. It has a mass of 3.5g. What is its volume
Leviafan [203]

Answer:

<h3>The answer is 5.34 mL</h3>

Explanation:

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

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

From the question

mass = 3.5 g

density = 0.655 g/mL

We have

volume =  \frac{3.5}{0.655}  \\  = 5.343511450...

We have the final answer as

<h3>5.34 mL</h3>
