Explanation:

Wire will always be stranded when it is larger than 6 AWG. Check more about American Wire Gauge below.

The American Wire Gauge (AWG) is known to be a kind of standardized wire gauge system that are known to be widely used in all parts of the United States. It centers around the diameter of electrical wire.

Conclusively, AWG general rules of thumb states that for every 6 gauge one has to lower the wire diameter and as such, Wire will always be stranded when it is larger than 6 AWG.

Answer:

Calipers

Explanation:

Calipers can also be used to measure holes of different shapes: square, rectangular, cylindrical or hexagonal. The lower set of jaws on the caliper is used to measure the outer diameter of a cylinder. It will also give you the total length or width of an object.

Explanation:

We need to prove that : [tex]\cos^2\theta+\cos^2\theta {\cdot} \cot^2\theta=\cot^2\theta[/tex]

Taking LHS : [tex]\cos^2\theta+\cos^2\theta {\cdot} \cot^2\theta[/tex]

Taking [tex]\cos^2\theta[/tex] common as follows :

[tex]\cos^2\theta(1+ \cot^2\theta)[/tex] ...(1)

We know that :

[tex]cosec^2\theta-\cot^2\theta=1\\\\cosec^2\theta=1+\cos^2\theta[/tex] ....(2)

Use equation (2) in equation (1) as follows :

[tex]\cos^2\theta{\cdot} cosec^2\theta[/tex]

We know that : [tex]cosec\theta=\dfrac{1}{\sin\theta}[/tex]

So,

[tex]\cos^2\theta{\cdot} \dfrac{1}{\sin^2\theta}\\\\=\cot^2\theta[/tex]

=RHS

Hence, LHS = RHS
