I believe the correct answer is C
11. Density of the piece of wood = 3000 g/cm³
12. Density of wooden block = 2 g/cm³. and it will not float in water.
13. Volume of the plastic ball should be 250 mL
14. Mass of the ice cube = 0.162 g
15. Volume of gasoline spilled is equal to 2000 mL

Explanation:</h3><h3>
</h3>
11.
<u>Formula:</u>
Given:
Mass of wood piece = 7500 g
Volume of wood piece = 2.5 cm³
Therefore,
Density of the piece of wood = 3000 g/cm³
12.
<u>Formula:</u>
Given:
Dimensions of wooden block = length × width × height = 5 cm × 4 cm × 2 cm
Mass = 80.0 g
Volume of wooden block =
Therefore,
Density of wooden block = 2 g/cm³.
Density of water is equal to 1 g/cm³
2 g/cm³ > 1 g/cm³
Since density of wooden block is greater than the density of water, the piece of wood will not float in water. It will sink.
13.
<u>Formula:</u>
Given:
Mass of the ball = 125 g
Density = 0.5 g/mL
Therefore,
Volume = 250 mL
Volume of the plastic ball should be 250 mL
14.
<u>Formula:</u>
Given:
Dimensions of ice cube = length × width × height = 3 cm × 3 cm × 3 cm
Density = 0.006 g/mL
Volume of ice cube =
Since,
Therefore,
Mass of the ice cube = 0.162 g.
15.
<u>Formula:</u>
Given:
Mass of gasoline = 1330 g
Density = 0.665 g/mL
Therefore,
Volume = 2000 mL
Volume of gasoline spilled is equal to 2000 mL
<h2>Answer:</h2>
<u>It is deflecting towards point X because it is hitting the proton or neutron</u>
<h2>Explanation:</h2>
The experiment shows the model of Rutherford atomic model and he concluded that every atom contains a nucleus where all of its positive charge and most of its mass are concentrated. So when the ray passes straight it meant that most of the place inside atom is empty but when it directly hits the neucleus it would come back at 180 degrees and when it passes with neucleus it bends away with the angle of 90 degrees.
The slope of the velocity is the graph at every point is the acceleration. Acceleration is zero wherever the slip of the graph is zero.
