.help!!! due today!!! what is happening and how it is demonstrating Newton’s 1st law. make sure you describe inertia and how it
relates to your demonstration.
okayyy so ive got to make a video and im planning on making this but then i have to explain how is it demonstrating Newton's 1st law and then I have to describe how Inertia relates to this demonstration, please help a girl out!!!

Explanation:
The given data is as follows.
Width of Styrofoam = 24.0 cm
Length of Styrofoam = 36.0 cm
Height of Styrofoam = 5.0 cm
Therefore, volume of the Styrofoam will be calculated as follows.
Volume = length × width × height
= (36.0 × 24.0 × 5.0)
= 4320
or, =
As Styrofoam partially sinks at 3.0 cm and total height of Styrofoam is 5.0 cm. Hence, height of Styrofoam above the water is (5.0 - 3 cm) = 2 cm.
So, volume of water displaced is as follows.
24.0 cm × 36.0 cm × 2.0 cm
=
Hence, mass of displaced water is as follows.
mass = density × volume
=
=
Since, book is placed on the Styrofoam. Therefore, mass of water displaced is also equal to the following.
Mass of water displaced = mass of book + mass of Styrofoam
= 1500 g + mass of Styrofoam
(1730 - 1500) g = mass of Styrofoam
mass of Styrofoam = 230 g
Therefore, calculate the density of Styrofoam as follows.
Density =
=
=
Thus, we can conclude that the density of Styrofoam is .
