Answer:3.47 m
Explanation:
Given
Temperature(T)=300 K
velocity(v)=1.5 m/s
At 300 K
![\mu =1.846 \times 10^{-5} Pa-s](https://tex.z-dn.net/?f=%5Cmu%20%3D1.846%20%5Ctimes%2010%5E%7B-5%7D%20Pa-s)
![\rho =1.77 kg/m^3](https://tex.z-dn.net/?f=%5Crho%20%3D1.77%20kg%2Fm%5E3)
And reynold's number is given by
![Re.=\frac{\rho v\time x}{\mu }](https://tex.z-dn.net/?f=Re.%3D%5Cfrac%7B%5Crho%20v%5Ctime%20x%7D%7B%5Cmu%20%7D)
![5\times 10^5=\frac{1.77\times 1.5\times x}{1.846\times 10^{-5}}](https://tex.z-dn.net/?f=5%5Ctimes%2010%5E5%3D%5Cfrac%7B1.77%5Ctimes%201.5%5Ctimes%20x%7D%7B1.846%5Ctimes%2010%5E%7B-5%7D%7D)
![x=\frac{5\times 10^5\times 1.846\times 10^{-5}}{1.77\times 1.5}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B5%5Ctimes%2010%5E5%5Ctimes%201.846%5Ctimes%2010%5E%7B-5%7D%7D%7B1.77%5Ctimes%201.5%7D)
x=3.47 m
Answer:
T=151 K, U=-1.848*10^6J
Explanation:
The given process occurs when the pressure is constant. Given gas follows the Ideal Gas Law:
pV=nRT
For the given scenario, we operate with the amount of the gas- n- calculated in moles. To find n, we use molar mass: M=102 g/mol.
Using the given mass m, molar mass M, we can get the following equation:
pV=mRT/M
To calculate change in the internal energy, we need to know initial and final temperatures. We can calculate both temperatures as:
T=pVM/(Rm); so initial T=302.61K and final T=151.289K
Now we can calculate change of U:
U=3/2 mRT/M using T- difference in temperatures
U=-1.848*10^6 J
Note, that the energy was taken away from the system.
Answer: Pi= 4 - 4/3 + 4/5 - 4/7 + 4/9 ...
Explanation:
Is the same as the example,
If Π/4 = 1 - 1/3 + 1/5 - 1/7 + 1/9 ...
Then
(Π/4 )*4= 4*(1 - 1/3 + 1/5 - 1/7 + 1/9 ...)
Π =4 - 4/3 + 4/5 - 4/7 + 4/9 ...
The way to write this is
Sum(from n=0 to n=inf) of (-1)^n 4/(2n+1)

Answer:
Side effects - sudden loss of balance/ repeated falls
Outputs - sever sickness and could me factual
Inputs/corrections of this- medications and experimental treatments to help slow the process of deterioration
Explanation:
Ohm's law is used here. V = IR, and variations. The voltage across all elements is the same in this parallel circuit. (V1 =V2 =V3)
The total supply current is the sum of the currents in each of the branches. (It = I1 +I2 +I3)
Rt = (8 V)/(8 A) = 1 Ω . . . . supply voltage divided by supply current
I3 = 8A -3A -4A = 1 A . . . . supply current not flowing through other branches
R1 = (8 V)/(3 A) = 8/3 Ω
R2 = (8 V)/(4 A) = 2 Ω
R3 = (8 V)/(I3) = (8 V)/(1 A) = 8 Ω
V1 = V2 = V3 = 8 V
