If two vehicles arrive at an uncontrolled intersection almost simultaneously, the driver of the car that arrived at the intersection last must give the right of way. The driver on the left has the right of way if you both arrive at the intersection at the same moment.
Which driver should yield at an uncontrolled T-intersection?
The driver of the car turning must give way to all oncoming cross traffic when two cars are approaching an uncontrolled "T" crossroads. You need to stop and give way to vehicles and pedestrians while entering a public road from a driveway or private road.
What is right of way?
When two vehicles or pedestrians are approaching from opposite directions, moving at a speed, and close enough to create a collision, one has the right to move forward legally before the other, unless the other gives way.

Answer:
b)1.08 N
Explanation:
Given that
velocity of air V= 45 m/s
Diameter of pipe = 2 cm
Force exerted by fluid F
So force exerted in x-direction
F=0.763 N
So force exerted in y-direction
F=0.763 N
So the resultant force R
R=1.079
So the force required to hold the pipe is 1.08 N.
Answer:
The electrical work for the process is 256.54 Btu.
Explanation:
From the ideal gas equation:
n = PV/RT
n is the number of moles of air in the tank
P is initial pressure of air = 50 lbf/in^2 = 50 lbf/in^2 × 4.4482 N/1 lbf × (1 in/0.0254m)^2 = 344736.2 N/m^2
V is volume of the tank = 40 ft^3 = 40 ft^3 × (1 m/3.2808 ft)^3 = 1.133 m^3
T is initial temperature of air = 120 °F = (120-32)/1.8 + 273 = 321.9 K
R is gas constant = 8.314 J/mol.k
n = 344736.2×1.133/8.314×321.9 = 145.94 mol
The thermodynamic process is an isothermal process because the temperature is kept constant.
W = nRTln(P1/P2) = 145.94×8.314×321.9×ln(50/25) = 145.94×8.314×321.9×0.693 = 270669 J = 270669 J × 1 Btu/1055.06 J = 256.54 Btu
