Answer:
Why are they used:
A carbon brush is a sliding contact used to transmit electrical current from a static to a rotating part in a motor or generator, and, as regards DC machines, ensuring a spark-free commutation.
At Divergent boundary, Crust is created.
At Convergent boundary, Crust is destroyed.
At Transform boundary, Crust is neither created nor destroyed.
<h3>What occurs at Divergent, Convergent and Transform boundary?</h3>
A divergent boundary occurs when two tectonic plates move away from each other. At this boundary, new oceanic crust is created.
Convergent boundaries are those boundaries where two plates are pushing into each other. These boundaries are pushing one of the plates under the other and back into the mantle to melt.
Transform boundaries are places where plates slide sideways past each other. At this boundary, Crust is neither created nor destroyed.

Answer:
Her measurements will be more accurate if she uses a cloth tape
measure instead of a ruler.
Explanation: (apex)
Answer:
Decrease the voltage,and do not change the resistance,the current will also decrease
Explanation:
Decrease the voltage,and do not change the resistance, the current will also decrease, because voltage is directly proportional to current
Answer:
Explanation:
Entropy is the degree of randomness of a system which it can increases as the temperature of the reactants is increased to yield product.
