Answer:
the volume of the gas decreases
Explanation:
As a balloon rises through the atmosphere, the air pressure around it decreases and the balloon expands.
Good luck!
Answer:
option A
Explanation:
Given,
wavelength of light,
refractive index of gasoline, n₁ = 1.40
Refractive index of water, n₂ = 1.33
thickness of the film, t = ?
Condition of constructive interference is given by

For minimum thickness of the film m = 0
From the question we can clearly observe that phase change from gasoline to air
so, n = 1.4


Hence, the correct answer is option A
Answer:
It won't increase according to Boyle's law
Explanation:
Volume of a gas varies inversely as the pressure so as more fixed volume of gas is added to the chamber the pressure reduces
It's D. Gravity holds everything in place
B. In step 3
They incorrectly solved for x. It should have been x=-3 and x=5
