Complete Question
The complete question is shown on the first uploaded image
Answer:
The pressure difference of the first bubble is
The pressure difference of the second bubble is
The pressure difference on the second bubble is higher than that of the first bubble so when the valve is opened pressure from second bubble will cause air to flow toward the first bubble making is bigger
Explanation:
From the question we are told that
The radius of the first bubble is
The radius of the second bubble is
The surface tension of the soap solution is
Generally according to the Laplace's Law for a spherical membrane the pressure difference is mathematically represented as
Now the pressure difference for the first bubble is mathematically evaluated as
substituting values
Now the pressure difference for the second bubble is mathematically evaluated as
The viscosity of magma is directly related to the silica content. That being said, the viscosity of magma is higher when the silica content is also high and it is a low viscosity magma when the silica content is also low. The silica content of low viscosity magma is approximately 45 - 55 wt%.
Answer:
1.2 m/s
0.31 m
0.15 m
Explanation:
Time period is
Frequency is
Velocity is given by
The waves are traveling at 1.2 m/s
Amplitude is given by
Amplitude is 0.31 m
If d = 0.3 m
The amplitude would be 0.15 m. The speed would remain the same.
Answer:
The correct option is;
The index of refraction of the second medium is lower
Explanation:
The index of refraction of a material indicates the magnitude of the optical density of a material. The index of refraction or the refractive index, n, are indices (ratio) of the speed of light through an optically dense medium relative to the speed of light through a vacuum.
The definition of the refractive index is the number of times light travelling through a medium would be slower than light travelling through vacuum
Therefore, the index of refraction of a second medium that is less optically dense than a first medium from which light originates and travels through it would be lower than the index of refraction of the first medium
