Possibly by the damage done compared to the previous ones.
Answer:
Faraday's law
, he direction of the magnetic field changes by 180º, in the polarity inversion processes, induces a voltage.
Explanation:
For this exercise let's use Faraday's law
E = - dФ / dt
Ф = B.A = B A cos θ
where B is the magnetic field, A is the area and θ is the angle between the field line and the normal to the area.
We can see that an electromotive force (voltage) is indexed when there is a variation of the field B, a variation of the area and change of the angle or when there is a combinational of them.
In this case, the magnitude of the field is constant, as the wire is rigid metal, the area is constant, but the direction of the magnetic field changes by 180º, in the polarity inversion processes, for which reason each change induces a voltage.
If a voltage is created in the ring, which has a resistance, a current is also generated in it.
Therefore the answer is If a current is created in the hoop
Answer:
Our star ,that is, Sun belong to Population I.
Explanation:
In 1940s, stars were divided into two categories by Wlter Baade:
a. Population I (Metal-rich)
b. Population II (Metal-poor)
Population I stars tend to be luminous, concentrated in the disks of spiral galaxies. They are still hot and young containing rich amount of heavy metals.
Sun falls in this category.
Population II stars tend to be less luminous found in the nucleus of the galaxy.
They are less hot. They are poor in heavy metals because they are old.
Answer:
B) 71.5 [km]
Explanation:
To solve this problem we will decompose each of the directions in the x & y axes.
To solve this problem we will decompose each of the directions in the x & y axes. also for a greater understanding of the angles, you should look at the attached image, which contains the orientations for each angle (clockwise or counterclockwise).
<u>59.0 km in a direction 30.0° east of north</u>
<u />
<u>58.0 km due south</u>
<u />
<u>It flies 100 km 30.0° north of west</u>
<u />
<u /><u />
<u />
Now we sum algebraically the components
Using the Pythagorean theorem we can find the magnitude of the displacement.
Answer:
Explanation:
The function of resistance in an electronic circuit is that it helps to limit the current in the circuit, so as to prevent it from high currents.
The resistor helps to limit the charge flowing through the circuit and also limits the flow rate of the charge.
The resistor opposes the flow of current through the circuit.
The initial and final voltage across the capacitor decreases.
