Answer:
constructively
6
Explanation:
c = Speed of light =
= Frequency = 1.667 GHz
= Path difference = 1.08 m
Wavelength is given by
Path difference is given by
As the integral multiple of wavelength gives path difference the waves will combine constructively.
The value of m is 6
Let's assume that the pressure given is 771 torr.
Answer:
747.44 torr
Explanation:
The eudiometer tube is a setup that collects gas in a liquid (generally water). After the thermal equilibrium, the gas becomes in equilibrium with the vapor of water above the liquid.
By Dalton's law, the total pressure of a mixture is the sum of the partial pressure of its components. The partial pressure is the pressure that the gas would have at the same conditions if it was alone. So, the pressure of the dry gas is its partial pressure.
The total pressure is the barometric pressure, and the partial pressure of the water vapor at 20°C is 23.56 torr (the value can be found at a thermodynamic table). So, the pressure of the dry gas (P) is:
771 = 23.56 + P
P = 771 - 23.56
P = 747.44 torr
Explanation:
You can solve for volume using radius or diameter.
Sphere Volume = 4/3 • π • r³ = ( π •d³)/6
We're given the diameter so let's use that.
Volume = PI * d^3 / 6
Volume = 3.14159 * 3.0^3 / 6
Volume = 3.14159 * 9 / 2
Volume = 14.137 cubic centimeters
