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].

Which lists types of materials from most conductive to least conductive?
insulator, semiconductor, conductor, superconductor
superconductor, conductor, semiconductor, insulator
conductor, insulator, semiconductor, superconductor
semiconductor, conductor, superconductor, insulator
Answer:
superconductor conductor semiconductor insulator
Explanation:
Edge
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.
Hence, option B is correct.

How do density, pressure, and temperature change as the depth of Earth increases? Question 5 options: Density, pressure, and temperature all increase as you go deeper into the Earth. Density, pressure, and temperature all decrease as you go deeper into the Earth. Density decreases, and pressure and temperature increase as you go deeper into the Earth. Density and pressure decrease, and temperature decreases as you go deeper into the Earth.
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.
