"Accuracy" would be the best option from the list regarding the property of a measurement that is best estimated from the percent error, since the higher the error is the lower the accuracy.

"Accuracy" would be the best option from the list regarding the property of a measurement that is best estimated from the percent error, since the higher the error is the lower the accuracy.

Explanation:

When taking scientific measurements, it's vital to be each correct and precise. Accuracy represents however shut a mensuration involves its true price. This can be vital as a result of unhealthy instrumentality, poor processing or human error will result in inaccurate results that aren't terribly getting ready to the reality.

Ede4ka [16]

Answer:

$H = 50.5 m$

Explanation:

As we know by work energy theorem that work done by all forces is equal to change in kinetic energy

So we know that

$W_f + W_g = \frac{1]{2}mv_f^2 - \frac{1}{2}mv_i^2$

so we know that

$W_f = -4000 J$

$v_f = 30 m/s$

$v_i = 2 m/s$

$m = 86 kg$

now we have

$mgH - 4000 = \frac{1}{2}(86)(30^2 - 2^2)$

$86(9.81)(H) - 4000 = 43(900 - 4)$

$H = 50.5 m$

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

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