Answer:
V2 = 21.44cm^3
Explanation:
Given that: the initial volume of the bubble = 1.3 cm^3
Depth = h = 160m
Where P2 is the atmospheric pressure = Patm
P1 is the pressure at depth 'h'
Density of water = ρ = 10^3kg/m^3
Patm = 1.013×10^5 Pa.
Patm = 101300Pa
g = 9.81m/s^2
P1 = P2+ρgh
P1 = Patm +ρgh
P1 = 1.013×10^5+10^3×9.81×160.
P1 = 101300+1569600
P1 = 1670900 Pa
For an ideal gas law
PV =nRT
P1V1/P2V2 = 1
V2 = ( P1/P2)V1
V2 = (P1/Patm)V1
V2 = ( 1670900 /101300 Pa) × 1.3
V2 = 1670900/101300
V2 = 16.494×1.3
V2 = 21.44cm^3
If they fit and have good durability
We have: v = d/t
From the expression, we conclude speed is indirectly proportional to speed.
So, the car which will take longer time must have the smallest speed. Among all the options Car C has the smallest speed. So, it would be your answer.
In short, Your Answer would be Option C) Car C will take longer time than any other.
Hope this helps!
Fusion occurs when low mass nuclei, such as hydrogen collide and combine to form nuclei with greater masses.
Fusion could be the world's answer to clean unlimited amounts of energy.
Fusion is extremely difficult to contain and maintain here on earth.
Explanation:
Nuclear fusion is the combination of light atomic nuclei to form nuclei with greater mass.
The sun is powered by chain reaction involving fusion of light hydrogen nuclei to produce a more massive atom of helium.
- As with all nuclear reaction, mass is equivalent to energy. These reactions takes place place in the nucleus of an atom where nuclear forces are broken .
- it is known that nuclear fusion produces far more energy than fission reaction.
- It produces less radioactive wastes and could be the world's clean source of unlimited amount of energy.
- The major problem with fusion is that it is difficult to start and requires a a lot of energy to initiate.
