Calculate the density of each ball. Use the formula

D = m/V
where D is the density, m is the mass, and V is the volume. Record your calculations in Table A of your Student Guide.

Given that the density of water is 1.0 g/cm3, make a prediction about whether each ball will float in water. Record your prediction in Table A.

Answer 1

The density of an object is the ratio of its mass and volume

The tennis ball would float in water, because it has a density of [tex]D = 0.37gcm^{-3}[/tex].The golf ball would sink because it has a density of [tex]D = 1.18gcm^{-3}[/tex]

The question is incomplete, as the mass and the volume (or radius) of the balls are not given.

So, I will give a general explanation.

Tennis Ball

Assume the mass of the tennis ball is:

[tex]m = 56g[/tex]

And the radius is:

[tex]r = 3.3cm[/tex]

The volume of the ball would be:

[tex]V = \frac 43 \pi r^3[/tex]

So, we have:

[tex]V = \frac 43 \times \frac{22}{7} \times 3.3^3[/tex]

[tex]V = 150.59[/tex]

The density of the ball is:

[tex]D = \frac mV[/tex]

So, we have:

[tex]D = \frac {56}{150.59}[/tex]

[tex]D = 0.37gcm^{-3}[/tex]

From the calculations above, we can conclude that the tennis ball will float in water, because [tex]0.37gcm^{-3}[/tex] is less than the density of water, [tex]1gcm^{-3[/tex].

Golf Ball

Assume:

[tex]m = 47g[/tex]

[tex]r = 2.12cm[/tex]

The volume is:

[tex]V = \frac 43 \pi r^3[/tex]

So, we have:

[tex]V = \frac 43 \times \frac{22}{7} \times 2.12^3[/tex]

[tex]V = 39.93[/tex]

So, the density is:

[tex]D = \frac mV[/tex]

[tex]D = \frac{47}{39.93}[/tex]

[tex]D = 1.18gcm^{-3}[/tex]

From the calculations above, we can conclude that the tennis ball will sink in water, because [tex]1.18gcm^{-3}[/tex] is greater than the density of water, [tex]1gcm^{-3[/tex].

Answer: Density, pressure, and temperature all increase as you go deeper into the Earth.

Explanation: Explanation: As you go deeper in depth, pressure increases. Density = mass/volume. The layers beneath us due to pressure get packed to the point of being very dense.

The list's type of materials from most conductive to the least conductive will be superconductor,conductor,semiconductor and insulator.

What are semiconductors?

Semiconductors are materials with conductivity intermediate between conductors and nonconductors or insulators. Semiconductors may be either compound like gallium arsenide.

The ideas, characteristics, and mathematical techniques that control semiconductors are explained in physics.

Silicon is employed in the manufacturing of electrical circuits, whereas gallium arsenide is used in solar cells, laser diodes, and other applications.

The types of materials from most conductive to least conductive will be superconductor,conductor,semiconductor and insulator.

How do you think density plays a role in the atmosphere?

Answers

Answer:
Also, gases like air are easily compressed. The weight of all the air above a given point in the atmosphere squeezes air molecules closer together. This causes the density to increase. The more air above a level (and hence the more weight of air above a level), the greater the compression.
