Answer:
Explanation:
As we know that resistance of one copper wire is given as
here we know that
now we have
now we know that such 17 resistors are connected in parallel so we have
Now if a single copper wire has same resistance then its diameter is D and it is given as
now from above two equations we have
now we have
Answer:
The rise from A to B is 0.887
Solution:
As per the question:
The following reading of an inverted staff is given as:
A = 2.915
B = -2.028
Here, for inverted staff, the greater reading shows greater elevation and lesser reading shows lower elevation.
Thus
The rise from A to B is given as:
A - B = 2.915 - 2.028 = 0.887

Answer:</h2>
<h2>
Cohesion </h2>
Is the attraction that molecules have for others of their same type.
<h2>
Adhesion </h2>
Is the attraction that molecules have for others of different type by intermolecular forces.
A good example of both is water that can stick to itself through hydrogen bonds (cohesion) and can also stick to a glass due to adhesion.
So, while Cohesion is the force of attraction between adjacent particles within the same body, Adhesion is the interaction between the surfaces of different bodies.
Answer:
The most significant difference between the static and current electricity is that in static electricity the charges are at rest and they are accumulating on the surface of the insulator. Whereas in current electricity the electrons are moving inside the conductor.
The answer is D. Unconditioned
The response to an unconditioned stimulus that occurs naturally without learning and involuntarily triggers reaction is known as an unconditioned response. For example, you smell your favorite food while being cook may make you instantly feel hungry.
