<h2>Answer: True </h2><h2 />
Faraday's Law (also known as Faraday's Law of Electromagnetic Induction) was formulated from the experiments made by him and states that:
<em>The voltage induced in a closed circuit is directly proportional to the speed with which the magnetic flux that crosses any surface with the circuit as edge changes in time
</em>
<em></em>
where:
is the Electric Field
is the infinitesimal element of the C contour
is the magnetic field density
is an arbitrary surface, whose edge is C
The negative sign indicates the direction of the induced current and refers to the opposition between the fields induced by the magnetic flux and the electromotive force. In addition, its consequences are also expressed in the Lenz law, which states that the induced electricity will be in a direction such that it opposes the variation of the magnetic flux that produced it as a consequence of the principle of conservation of energy.
Therefore:
<h2>If he minus sign were not in Faraday's law it would lead to a violation of the law of conservation of energy

Answer:
The direction of current in the second wire will be upward.
Explanation:
We first need to find the direction of the magnetic field due to the first wire using the right-hand thumb rule.
Knowing that, one can easily find the direction of the second wire by using the right-hand rule.
The force per unit length on wire 2 due to wire 1 is given by,
Therefore,

The ideal spring equation is
Stretch = K times Force .
This says that the stretch is directly proportional to the force.
In simple English, that means that if you double the force, then
you double the stretch, and if you multiply the force by π or
any other number, you multiply the stretch by the same number.
So you can always write a proportion for a spring:
Stretch₁ / Force₁ = Stretch₂ / Force₂ .
Part A:
In Part-A of this question, the force is increased to (2.5 / 2.0) = 1.25 times .
So the stretch is also increased to 1.25 times .
(1.25) x (6.1 cm) = 7.625 cm .
Answer: As Earth rotates, the Moon's gravity causes the oceans to seem to rise and fall. ... There is a little bit of friction between the tides and the turning Earth, causing the rotation to slow down just a little. As Earth slows, it lets the Moon creep away.
