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
The answer is Density !, Do you also need an example ?

The forces a piano tuner applies to stretch the steel piano wire willl be 1.4 × 10¹¹ N.
<h3>What is force?</h3>
Force is defined as the push or pulls applied to the body. Sometimes it is used to change the shape, size, and direction of the body. Force is defined as the product of mass and acceleration. Its unit is Newton.
The application of a force may be used to describe the steel as an elastic element within a certain range of applied force.
Given data;
Young modulus, E=2.10 × 10¹¹ N/m²
Cross-sectional area,A
Final length,
Initial length,
Hence, the force a piano tuner applies to stretch the steel piano wire willl be 1.4 × 10¹¹ N.

Answer:
The best statement would be scientific laws describe phenomenon that can be observed in nature. Sometimes, laws are related to principle defining and predicting a certain happening without explaining its nature. It is different with ‘hypothesis’ or ‘theory’ as it aims to answer only the ‘what’ (observation only)...
Explanation:
hopefully this is correct
