<u><em>Answer:</em></u>498.82 cg is equivalent to 4988.2 mg
<u><em>Explanation:</em></u>cg stands form centigrams
mg stands for milligrams
From the standards of conversion, to convert from centi to milli, we multiply the amount ny 10
<u>This means that:</u>
1 centigram = 10 milligram
To convert 498.82 cg to mg, all we have to do is <u>cross multiplication</u> as follows:
1 cg ..................> 10 mg
498.82 cg .........> ?? mg
498.82 cg = </span>

<span> = 4988.2 mg
Hope this helps :)</span>
In simple words, smoothing can be defined as the circuit which is done to eliminate the ripple from the yield of a direct current power supply.
<u>Explanation:</u>
<u>Necessity of smoothing:</u>
- Smoothing can be also applied in the form of a capacitor that acts to decrease or level out variations in a signal. And these capacitors are mostly used after power supply in voltage.
- The yield DC voltage of a half-wave rectifier provided in the figure of a sinusoidal wave.
- In a method to provide a constant DC voltage from a corrected AC source, a filter or smoothing circuit is required.

Gases have heavier molecules. Since all gases have the same average kinetic energy at the same temperature, lighter molecules move faster and heavier molecules move slower on average.
Answer:

Explanation:
Given that,
The magnitude of magnetic field, B = 0.55 T
The radus of the loop, r = 43 cm = 0.43 m
The current in the loop, I = 5.8 mA = 0.0058 A
We need to find the magnetic moment of the loop. It is given by the relation as follows :

Put all the values,

So, the magnetic moment of the loop is equal to
.
D. both b. and c. Obviously adding more gas but reducing the volume because of the limited space in the container.
