It defines that if two thermodynamic systems are each in equilibrium with a third system, then they are in equilibrium with each other.
Answer:
240 kPa
Explanation:
The ideal gas law states:

where
p is the gas pressure
V is the gas volume
n is the number of moles
R is the gas constant
T is the absolute temperature of the gas
For a fixed amount of gas, n and R are constant, so we can rewrite the equation as

For the gas in the problem, which undergoes a transformation, this can be rewritten as

where we have:
is the initial pressure
is the initial volume
is the initial temperature
is the final pressure
is the final volume
is the final temperature
Solving the formula for p2, we find the final pressure of the gas:

Answer: A.0,0097s
Mas a unidade aí deveria ser Hertz (Hz)
Explanation:
Answer:
30 cm
Explanation:
Hi! Lets find the angles for the first and second order maxima
The first order maximum will occur for Ф=0
The second order maximum will satisfy the following relationship:
sinФ = λ/d
Where λ = 600 x 10^-9 m and d = 5 x 10^-5 m
Therefore:
sinФ = 0.012
And the vertical distance bewteen the first and second will be given by:
l = (2.5 m) tanФ
But since 2.5 m>>0.05 mm ; sinФ≈tanФ
Therefore:
l = (2.5 m) sinФ
l = 0.03 m = 30 cm
This can be soved using pathagorian theorm
square root d= under root of (square root of x+square root of y). it is 509 approximately
