D because the rock is making it lean less to the man so that means the rock has more mass
mechanical waves are classified by how they move. there are two types of mechanical waves:transverse waves and longitudinal waves.
Units are all fine. No need of conversion.
Just Use the formula:
V = mass / density
V = 76.2 / 13.6 = 5.6 mL
Answer:
<h2>Density = 0.75 g/cm³</h2>
Explanation:
Density of a substance is given by
<h3>
</h3>
From the question
mass of the wood = 180 g
Since the wood is a cuboid we can find the volume using the formula
Volume = length × width × height
From the question
length = 10cm
width = 6 cm
height = 4 cm
Volume = 10 × 6 × 4 = 240 cm³
Substitute the values into the above formula and solve for the Density
That's
<h3>
</h3>
We have the final answer as
<h3>Density = 0.75 g/cm³</h3>
