Answer:

Explanation:
GIVEN,
mass of electron = 9.1 x 10 kg
Radius = 5.3 x 10 m
pulling force = 8.2 x 10 N
Required centripetal for (Fe) for circular motion will be provided with electrical force (F)




ω = 4.12 x 10¹⁶ rad/s


Answer:
A volcano that erupts frequently.
Explanation:
Both.
But the volcano that hasn't erupted in 100 years would probably be more dangerous because you wouldn't be prepared for its explosion as you would be for the one that erupts frequently.
Glad I could help!!
In semiconductors, you can change how easily electrons move through them. That is option 2.
<h3>What are semiconductors?</h3><h3 />
Semiconductors is defined as those substances that possess the characteristics of both metal and non metal.
Examples of semiconductors include the silicon, germanium, and gallium arsenide elements.
The semiconductors are able to conduct electricity through the presence of electrons and holes in them.
The movement of these electrons can be controlled through the addition of impurities to the semiconductor material.
Therefore, in semiconductors, you can change how easily electrons move through them.
