Answer:
Induced emf,
Explanation:
The varying magnetic field with time t is given by according to equation as :
Where
are constant
Let is the emf induced in the loop as a function of time. We know that the rate of change of magnetic flux is equal to the induced emf as:
So, the induced emf in the loop as a function of time is . Hence, this is the required solution.
"Wind patterns" is the one among the following choices given in the question that <span>involves convection currents. The correct option among all the options that are given in the question is the second option or option "B". The other choices can be easily negated. i hope that this is the answer that has helped you.</span>
The change in momentum of an object equals the impulse applied to it
Answer:
(A) Consists of a small number of tiny particles that are far apart- relative in their size.
Explanation:
An <em>ideal gas</em> is defined as a simplification of a real gas, with punctual particles, in which all collisions are elastic, with random displacements and with no attractive force between them.
The assumption of the particles being punctual make clear that they do not have size at all. So if they were far apart-relative in their size, they can not collide each other, that is why assumption (B) can not be possible (<u><em>for that particular case</em></u>).
It is clear that (A) is not an assumption for an ideal gas, because do not fit in any of its properties.
Elastic collision: It is a case in which the energy is conserved (Kinetic Energy).
Kinetic Energy: It is the energy that will have an object as a consequence of its movement.
