Answer:
τ = 0.25 lbf/in²
Explanation:
given that the oil viscosity, μ = 2.415 lb/ft-s
gap between plates = 1/4 inches = 1/4*12 = 1/48 ft
recall from newtons law of viscosity;
shear stress τ = μ du/dy =
τ = (2.415 lb/ft-s) (10 ft/s)/(1/48) ft
τ = 1159.2 lb/ft-s²
we know that, 1 slug = 32.174 lb
lb = 1/32.174 slug
∴ τ = 1159.2/32.174 slug/ft-s² = 36 slug/ft-s²
τ = 36 slug/ft-s²
multiply both the numerator and denominator by ft, this gives
τ = 36 slug-ft/ft²-s²
τ = 36 lbf/ft² where 1 slug-ft/s² = 1lbf
since 1 ft = 12 inch = 1 ft² = 12² in² = 144 in²
∴ τ = 36/144 lbf /in² = 0.25 lbf/in²
τ = 0.25 lbf/in²
Answer:
the data are inadequate
Explanation:
<u>If there are 15 people on the team, and only five have been asked about the mascot, </u><u>this means the data collecting is wrong, and the result doesn’t include thoughts of the majority</u>. If Diana and Kinsey want to have adequate data,<u> they should ask as many as possible, if not all players in the team</u>. This would truly show what the majority wants meaning it will show what the team wants. This kind of complete data correcting is the correct one.
She should create a computer animated view of the design to walk the client through it so that client will understand and get the picture of the design.
Answer:
The answer is 200 Meters
Explanation:
At what distance should the warning triangle be placed if a vehicle breaks down on the autobahn?
200 Meters
The Autobahn is the federal controlled-access highway system in Germany. The official German term is Bundesautobahn, which translates as "federal motorway". The literal meaning of the word Bundesautobahn is "Federal Auto Track".
Answer:
The final pressure is 3.16 torr
Solution:
As per the question:
The reduced pressure after drop in it, P' = 3 torr = 
At the end of pumping, temperature of air, 
After the rise in the air temperature, 
Now, we know the ideal gas eqn:
PV = mRT
So
(1)
where
P = Pressure
V = Volume
R = Rydberg's constant
T = Temperature
Using eqn (1):
Now, at constant volume the final pressure, P' is given by:
