Suppose that all the dislocations in 4700 mm3 of crystal were somehow removed and linked end to end. Given 1 m = 0.0006214 mile,
san4es73 [151]

Answer:

a. The required chain length = 292.1 miles

b. Length of the required chain = 29.2*10^6miles

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 = 10^5mm^{-2}

and volume is given as = 4700mm^3

=10^5*4700mm(\frac{1mi}{1.609*10^6mm} )=292.1miles

b. To find the length of required chain

length of required chain = dislocation density * volume

where dislocation density = 10^{10}mm^{-2}

we substitute in the equation above to get

=10^{10}mm^{-2}*4700mm^3\\=47*10^{12}mm*(\frac{1mile}{1.609*10^6mm} )=29.2*10^{6}miles

Calculate the reading on voltmeter v²​
Yuliya22 [10]

The reading of the voltmeter can be determined by finding the potential difference across the 2Ω resistance by using the value of current in the circuit. V=IR, here V is the potential difference across a resistance R through which a current I is flowing.

What change occurs to the gravitational force of attraction between two bodies when the
Lisa [10]

Answer:

when the radius is halved, F becomes 4 times

Explanation:

<u><em>The formula is given by</em></u>

F = \frac{Gm1m2}{r^2}

<u><em>When r is halved:</em></u>

F = \frac{Gm1m2}{(1/2r)^2}

=> F = \frac{Gm1m2}{1/4 r^2}

=> F = 4(\frac{Gm1m2}{r^2} )

<u><em>This means when the radius is halved, F becomes 4 times</em></u>
