1- The preexponential and activation energy for the diffusion of iron in cobalt are 1.1×10-5 m 2 /s and 253,300 J/mol, respectively. At what temperature will the diffusion coefficient have a value of 2.1×10-5 m 2 /s ?

Answers

The temperature at which the diffusion coefficient have a value of 2.1×10-5 m 2 /s is  -47078 K.

Using the relation;

logD = logDo - Ea/2.303RT

D = diffusion coefficient

Do =  preexponential

Ea = activation energy

R = gas constant

T = temperature

Substituting values;

log(2.1×10-5)= log (1.1×10-5 ) - 253,300/2.303 × 8.314 × T

log(2.1×10-5) -  log (1.1×10-5 ) =  - 253,300/2.303 × 8.314 × T

log[2.1×10-5/1.1×10-5] = - 253,300/2.303 × 8.314 × T

0.281 × (2.303 × 8.314 × T) = - 253,300

T =  - 253,300/2.303 × 0.281 × 8.314

T = -47078 K

B. Check the condition of all circuit
breakers in the load center.
O C. Measure the voltage on the conductor
with a known good meter.
O D. Consult the NEC.

Answers

Answer:

D. Measure the voltage on the conductor with a known good meter

Explanation:

In a safe approach to electrical work,the thing that you should always do immediately before touching any electrical conductor is  C. Measure the voltage on the conductor with a known good meter.

What should be done immediately before touching any electrical conductor?

One should never touch any wires or conductors until you are certain that their electrical supply has been turned off. Circuits must be locked out and marked with a tag to prevent re-energizing them. A conductor is always risky. Before working on a circuit, always test to make sure it is deenergized.

The action you should always do right away before touching any electrical conductor is  the safest approach to electrical work. Use a reputable meter to measure the voltage across the conductor.

Why are you asked to draw a sketch of a Bridge-Design on a graph sheet/A4 sheet?

Answers

Engineers or architects can be asked to draw a sketch of a bridge-design on a graph sheet or A4 paper to communicate their ideas and scale their drawings.

Architectural sketches are about the communication of ideas. Engineers and architects use hand sketching to clarify elements of the design to the contractor or client.

It should be noted that drawings can also be drawn on a graph sheet or A4 paper to represent the detail before it's eventually constructed.

Scale drawings are used for the illustration of items that are not convenient to draw their actual size. In the construction industry, scales are used depending on the nature of the drawing. Drawings can be made on a graph or A4 paper due to the ease of printing, reproducing, and resizing the drawings.

Answers

Pseudocodes are used as a prototype of an actual program.

The error in the pseudocode is that, the while loop in the pseudocode will run endlessly.

From the pseudocode, the first line is:

Declare Boolean finished = false

The while loop is created to keep running as long as finished = false.

So, for the while loop to end, the finished variable must be updated to true.

This action is not implemented in the pseudocode.
