A) If the pressure in a gas is doubled while its volume is held constant, by what factor do vrms change?
1 answer:
Answer:
Explanation:
The rms velocity of the gas molecules is directly proportional to the square root of absolute temperature of the gas.
As the pressure is doubled and the volume is constant s the temperature also doubled and the rms velocity becomes √2 times the present value.
(B) Similarly, the average velocity of gas molecules is directly proportional to the square root of the absolute temperature of the gas.
As pressure is doubled and the volume is constant s the temperature also doubled and the average velocity becomes √2 times the present value.

Answer:
Length of copper wire, l = 785 meters
Explanation:
Given that,
Resistance of the copper wire, R = 0.172 ohms
Area of cross section,
Resistivity of copper,
The resistance of a wire is given by :
l = 785 meters
So, the length of the copper wire is 785 meters. Hence, this is the required solution.
Answer:
the only effect it has is to create more induced charge at the closest points, but the net face remains zero, so it has no effect on the flow.
Explanation:
We can answer this exercise using Gauss's law
Ф = ∫ e . dA = / ε₀
field flow is directly proportionate to the charge found inside it, therefore if we place a Gaussian surface outside the plastic spherical shell. the flow must be zero since the charge of the sphere is equal induced in the shell, for which the net charge is zero. we see with this analysis that this shell meets the requirement to block the elective field
From the same Gaussian law it follows that if the sphere is not in the center, the only effect it has is to create more induced charge at the closest points, but the net face remains zero, so it has no effect on the flow , so no matter where the sphere is, the total induced charge is always equal to the charge on the sphere.
