Answer:
a. The required chain length = 292.1 miles
b. Length of the required chain = 
Explanation:
Cold work is the work performed on a material at a temperature below the re-crystallization temperature of the material.
Dislocation density is the measure of the total number of dislocation of a crystalline material of unit volume.
Deformation is the process of change in an objects shape due to the application of force
a. In order to find the length of required chain for the given dislocation density
length of required chain = total length of dislocation line = dislocation density * volume
where dislocation density = 
and volume is given as = 
b. To find the length of required chain
length of required chain = dislocation density * volume
where dislocation density = 
we substitute in the equation above to get
The amount left of a radioactive sample amount N0 if the decay constant is 0.00125 seconds and the time is 180 seconds is 0.7999 N.
<h3>What is half-life?</h3>
The time it takes for half of the original population of radioactive atoms to decay is called the half-life. The relationship between the half-life T1/2 and the decay constant is given by T1/2 = 0.693/λ.
- N=N0e−λt
- given λ = 0.00125 seconds
- t = 180 seconds
- Now putting values.
- N=N0e−λt = 0.799
- N= 0.7999.

<span>When you are setting up your budget, it is easier to start by setting your budgeting amounts based on the average of your last three months of spending. Many budgeting programs can import past transactions and help you come up with the estimates that you need for your budget. Then you can begin to make adjustments after you have those initial amounts.
</span>
The two main goals are to spend less than you earn and to know where your money is going. Once you have a working budget you can work towards your other goals of saving money and getting out of debt. It is important to avoid theses common budgeting mistakes <span>when setting up your budget.

Answer:
43.7 °C
Explanation:
= Coefficient of linear expansion of brass = 
= Coefficient of linear expansion of steel = 
= Initial length of brass = 31 cm
= Initial length of steel = 11 m
= Total change in length = 3 mm
Total change in length would be
The final temperature is 43.7 °C
