D) pumice.
Explanation:
The rock that most likely floats on water after the eruption of Krakatoa volcano is a Pumice.
Pumice is the only rock that floats on water. It's density is less than that of water and so, it will stay afloat.
- From the given options, pumice is the only extrusive igneous rock. Volcanic eruptions are extrusive in nature.
- Granite is an intrusive plutonic rock
- Phyllite and marble are metamorphic rocks.

<h2>
Answer: The volume will triple (increase by a factor of three).</h2>
Explanation:
The expression for an Ideal Gas is:
(1)
Where:
is the pressure of the gas
is the volume of the gas
the number of moles of gas
is the gas constant
is the absolute temperature of the gas
Finding :
(2)
If we are told the the amount of gas and pressure remain constant, but we increase the temperature by a factor of three; we will have to rewrite (2) with the new temperature :
(3)
(4)
Now, if we compare (2) with (4), it is clearly noticeable the volume of the gas has increased by a factor of 3.
<span>95m /2 = 47.5m
47.5m = Vocos38t
</span><span>Vy = Voy -9.8t
0 = Vosin38 - 9.8t
0 = Vosin38 - 9.8(47.5 / Vocos38)
0 = Vo^2(0.62) - 590.7
</span>
<span>Vo = 30.87 m/s

Hope this helps
The correct answer is not listed among the choices.
m = w/g
m = 1,125 / 9.8
m = 114.8 kilograms
