Explanation:
<u>Ohmic Behavior:</u>
If the current "I" produced in a conductor due to voltage "V" applied across it, is directly proportional to that voltage while the resistance of the conductor is same/constant, the material is said to be ohmic material or possessing ohmic behavior. If the resistance of a conductor doesn't remain the same due to heat, material property or any other reason, non-ohmic behavior will be observed.
<u>Thermal Expansion vs Ohmic/Non-ohmic property:</u>
For a linear conductor, thermal expansion (may be due to heat produced in result of current flow) increases length of the material due to which its resistance increases directly. Whenever the resistance increases during the flow of a current, the non-ohmic behavior arises.
R = ρL/A
where,
R=Resistance of conductor
ρ=Resistivity of material
L=length of conductor
A=Cross-sectional area of the conductor.
But,
usually this change in length and consequently change is resistance is very minor, so ignoring this change, the non-ohmic property of material will be minor too.
<u>Non-Ohmic Property:</u>
Current flows in a conductor due to flow of electrons in it. When these flowing electrons interacts with other particles (electron or atoms' nucleus) heat is produced. Due to this heat, atomic particles vibrates with more speed resulting in more hindrance/resistance in the flow of electron i.e. Resistance of material is now increased, so this will result in Non-ohmic behavior because now for the same value of applied voltage V, the flow of electron (Current) will be lesser. This will result in deviation from straight line graph as well (picture is attached)

He should get a job in engineering to see what it's like to work in the field.
Key to the success of grid computing is a(n) central server that acts as a grid leader and traffic monitor.
<h3>
what is grid computing?</h3>
- The utilisation of widely dispersed computer resources is known as grid computing.
- A computer grid can be compared to a distributed system with multiple files and non-interactive tasks.
- In contrast to traditional high-performance computing systems like cluster computing, grid computers have each node configured to run a unique job or application.
- Additionally, compared to cluster computers, grid computers are typically more diverse and geographically distributed (and hence not physically connected).
- Although a single grid might be devoted to a certain application, a grid is often utilised for a number of different things. Software libraries for general-purpose grid middleware are frequently used to build grids. There is a wide range of grid sizes.

Answer:
The molecular weight of the gas mixture is 35.38 g/mol.
Explanation:
The molecular weight of the gas can be found using the following equation:
Where:
m: is the mass = 230 g
n: is the number of moles
First, we need to find the number of moles using Ideal Gas Law:
Where:
P: is the pressure = 135 psi
V: is the volume = 15 L
R: is the gas constant = 0.082 L*atm/(K*mol)
T: is the temperature = 465 °R (K = R*5/9)
Finally, the molecular weight of the gas is:
Therefore, the molecular weight of the gas mixture is 35.38 g/mol.
I hope it helps you!
Answer:
<h2>destabilizing load:</h2>
The common definition of a destabilising load is if the load is free to move with the flange, it's a destabilising load. The stress due to the lateral bending of the flange is increased, which means the beam is closer to buckling than it would be without the additional moment.
<h2>normal load:</h2>
Something that is normal is usual and ordinary, and is what people expect.The leakage crack is a postulated crack that, under normal operating loads (pressure, weight, thermal expansion), will discharge a detectable amount of fluid.
The leak rates are calculated based on the flaw geometry, the applied loads, and the crack morphology. The crack opening displacement and crack morphology are typically based on two cases: (1) a fatigue-induced transgranular crack and (2) a corrosion-induced intergranular crack. The leak flow through a crack must be analyzed with the correct thermohydraulic model that captures, as the fluid progresses from the inner diameter (ID) to the outer diameter (OD), a subcooled phase (pressurized hot water) at the ID entrance into the crack, a steam formation phase somewhere between the ID and the OD, and then a two-phase flow region toward the OD, and discharge into the containment environment.
