Answer:
204.5 molecules
Explanation:
Pressure, P = 1.01 x 10^-13 Pa
Volume, V = 9.28 cm^3 = 9.28 x 10^-6 m^3
Temperature, T = 332 K
Gas constant, R = 8.314 in MKS system
Let n be the number of moles
Use ideal gas equation
P x V = n x R x T
1.01 x 10^-13 x 9.28 x 10^-6 = n x 8.314 x 332
n = 3.396 x 10^-22
According to the Avagadro's law
1 mole of the substance contains = 6.023 x 10^23 molecules
so, 3.396 x 10^-22 moles contains = 6.023 x 10^23 x 3.396 x 10^-22
= 204.5 molecules
Answer:
Explanation:
For the problem, we should have same reynolds number
ρvd/mu = constant
1000×1×10⁻³×0.3×10⁻³/1.002×10⁻³ = 1400×0.5×d/600
d = 25.66 cm
We start to see more off the dark side (waning) or more of the light side (waxing) the more of the dark side we see, the less moon there seems to be. The more light side, the more moon.
The Answer to this question would Be A

Answer:
Explanation:
firstly we have to find the frequency and then the angular frequency.
The frequency will be:
The angular frequency is:
ω
ω
ω
Now we can apply simple pendulum relationship
ω
make g the subject of the formula
