The EM spectrum has no limits. Any frequency you can imagine
is the frequency of some electromagnetic radiation somewhere.
Answer:
Peer reviews are important because individuals with similar background knowledge are used to review work to detect inaccuracies or deficiencies in the work.
Explanation:
Those individuals with similar educational and work background knowledge can more accurately review work since they have the required knowledge base for the subject.
The charges align themselves so that the conductor's internal field is zero.
<h3>What occurs if a charged surface is in close proximity to a conducting surface?</h3>
Induced charges are created on the conductor when a charge is brought close to it. The internal free charges of the conductor, however, are gathered throughout its surface because the electric field inside the conductor must be zero in order to defeat the electric field of induced charges.
<h3>What takes place within a conductor?</h3>
A substance that has a lot of free electrons accessible for the flow of current is said to be a conductor. Since there are numerous electrons, a powerful force of repulsion exists between them as well. As a result, the electrons move to lessen their attraction for one another.

Answer:
Explanation:
Needed torque can be estimated by means of the Theorem of Angular Momentum Conservation and Impact Theorem. The center of mass of the system is:
Let assume that both masses can be modelled as particles, then:
![[(1.51\,kg)\cdot (0.923\,m)^{2} + (1.97\,kg)\cdot (0.707\,m)^{2}]\cdot (38\,\frac{rev}{min} )\cdot (\frac{2\pi\,rad}{1\,rev} )\cdot (\frac{1\,min}{60\,s} ) -T\cdot (7.5\,s) = 0\,\frac{kg\cdot m^{2}}{s}](https://tex.z-dn.net/?f=%5B%281.51%5C%2Ckg%29%5Ccdot%20%280.923%5C%2Cm%29%5E%7B2%7D%20%2B%20%281.97%5C%2Ckg%29%5Ccdot%20%280.707%5C%2Cm%29%5E%7B2%7D%5D%5Ccdot%20%2838%5C%2C%5Cfrac%7Brev%7D%7Bmin%7D%20%29%5Ccdot%20%28%5Cfrac%7B2%5Cpi%5C%2Crad%7D%7B1%5C%2Crev%7D%20%29%5Ccdot%20%28%5Cfrac%7B1%5C%2Cmin%7D%7B60%5C%2Cs%7D%20%29%20-T%5Ccdot%20%287.5%5C%2Cs%29%20%3D%200%5C%2C%5Cfrac%7Bkg%5Ccdot%20m%5E%7B2%7D%7D%7Bs%7D)
The torque needed to stop the system is:
Answer:
Explanation:
The distance will be the total distannce covered during the journey.
If you move 3 meters East and move 4 meters north, then the distance will be calculated as;
Distance = distnace through East+distance through north
Distance = 3m + 4m
<em>Distance = 7m</em>
Displacement is the distance covered in a specified direction. It is the shortest distance covered by me. This can be gotten using the Pythagoras theorem.
d² = 3²+4²
d² = 9+16
d² = 25
d = √25
d = 5m
<em>Hence the displacement of the object is 5metres</em>
