We can confirm that the difference between a comet and an asteroid lies in their compositions and physical characteristics <u>derived from those compositions</u>.
As stated in the question, the main difference between an asteroid and a comet is their compositions, meaning the materials from which they form.
Asteroids are rocky objects which a heavy metal composition, while comets tend to be made of dust, ice, and <em><u>some </u></em>rocky material. Some extra differences include:
- Comets reflect a steady amount of light (because of their ice composition)
- Asteroids will <em><u>reflect light at random intervals due to some metals that may be present on their surface</u></em>
- Comets tend to have a tail made of water from the melting ice when reflecting sunlight.
Therefore, we can confirm that the main difference between asteroids and comets is their compositions, which lead to distinct physical characteristics.

Answer:
The maximum value of the magnetic field in the wave is 
Explanation:
Given that,
Average value of pointing vector = 0.724 W/m²
We need to calculate the magnetic field
Using formula of pointing vector

The average value of pointing vector

We know that,

Put the value of
in equation (II)

substitute the value in the formula

The maximum value of the magnetic field in the wave is 
Answer:
I mean its probably a magnet so look at the fraction of the initial Kinetic Energy of magnets
