Control rods<span> are </span>rods<span>, plates, or tubes containing a neutron absorbing material (material with high absorbtion cross-section for thermal neutron) such as boron, hafnium, cadmium, etc., used to </span>control<span> the power of a nuclear reactor.
so the statement that describe a control rod is:
</span><span>Control rods are lowered into the reactor to slow down the reaction by absorbing neutrons.</span>
If you add 2 miles from west then 2 miles east then it would 4 miles all together.
Answer:
Option (B)
Explanation:
A heterogeneous mixture is usually defined as a combination of two or more chemical substances. It can be also elements as well as compounds. These contrasting components can be easily separated from one another by means of physical process. These are comprised of substances that are not even everywhere. There is variation in it.
Thus, the correct answer is option (B).
The superconducting magnets are able to generate powerful magnetic fields because they have no electrical resistance.
To find the answer, we have to know more about the superconducting magnets.
<h3>What is superconducting magnet?</h3>
- An example of an electromagnet is a superconducting magnet.
- They are constructed from coils of superconducting wire and must be used while being chilled to cryogenic temperatures.
- Because the wire encircling the magnet has no electrical resistance when it is in its superconducting condition, they may produce powerful magnetic fields.
- Because of this, the magnet can conduct far greater electrical currents than the typical electromagnet.
Thus, we can conclude that, the superconducting magnets are able to generate powerful magnetic fields because they have no electrical resistance.
