Answer:
You should follow the officer's instruction and proceed with caution
Explanation:
You should always follow the lawful orders of an officer regardless of standard traffic procedures. This is typical because the officer needed to take control of a particular situation due to a crash or other potential hazard, making manual commands safer than standard road rules.
Answer:
The correct answer is "4.8137 m³". The further explanation is given below.
Explanation:
Firstly we have to calculate the concentration of Se:


Concentration the fish can take:

According to the general dilution principle will be:
⇒ 
The volume that can take the farmer will be:


On converting this into m³, we get
= 
Finally the volume the farmer can remove would be:


Answer:
The initial temperature is 649 K (376 °C).
The final pressure is 0.965 MPa
Explanation:
From the ideal gas equation
PV = nRT
P is the initial pressure of water = 2 MPa = 2×10^6 Pa
V is intial volume = 150 L = 150/1000 = 0.15 m^3
n is the number of moles of water in the container = mass/MW = 1000 g/18 g/mol = 55.6 mol
R is gas constant = 8.314 m^3.Pa/mol.K
T (initial temperature) = PV/nR = (2×10^6 × 0.15)/(55.6 × 8.314) = 649 K = 649 - 273 = 376 °C
From pressure law,
P1/T1 = P2/T2
P2 (final pressure) = P1T2/T1
T2 (final temperature) = 40 °C = 40 + 273 = 313 K
P1 (initial pressure) = 2 MPa
T1 (initial temperature) = 649 K
P2 = 2 × 313/649 = 0.965 MPa
Answer:
Agricultural engineers attempt to solve agricultural problems concerning power supplies, the efficiency of machinery, the use of structures and facilities, pollution and environmental issues, and the storage and processing of agricultural products.
