To solve this problem we will apply the concepts related to magnetic flux and induced voltage. This last expression understood as the variation of the magnetic flux over time and, in turn, the magnetic flux expressed as the variation of the magnetic field in a certain area.
Magnetic flux through the circular coil is given as
The induced voltage is the change of the magnetic flux across the time, then
At the same time the magnetic flux through the square coil would be given as,
And the induced voltage EMF will be
Equating both expression we have
Therefore the emf induced in the square coil is 0.23355V
When breathing out, it pushes your diaphragm, the muscle below your lungs, up, which then causes the air to leave your lungs.
The anomalous expansion of water refers to the fact that water, unlike most substances, expands when it freezes. The density of water increases as temperature decreases but reaches a maximum at 4° C then begins to expand.
When liquid water is cooled, it contracts like one would expect until a temperature of approximately 4 degrees Celsius is reached. After that, it expands slightly until it reaches the freezing point, and then when it freezes it expands by approximately 9%.
The correct answer is
<span>b. increases with the square of speed
In fact, the kinetic energy of a moving object is given by
</span>
<span>where m is the mass of the object and v is its speed. We see that the kinetic energy is directly proportional to the square of the speed, therefore option B is the correct one.</span>
<span>The answer would be, C. The reactions go to completion</span>
