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
Answer:
c) true. With the magnetic field you can determine the Poynting vector and this is equal to the intensity of the wave
Explanation:
An electromagnetic wave carries energy that is given by the vector of poyntíng
S = 1 / μ₀ E x B
The electric and magnetic fields are related
E = c B
Substituting
S = c /μ₀ B² / 2
The two comes from the average value
Let's examine the claims
a) false to determine the wavelength the frequency is needed
b) False. To find the electric field you need the magnetic field
c) true. With the magnetic field you can determine the Poynting vector and this is equal to the intensity of the wave
A galaxy because that is the largest group and contains many things.
