Hello!!!
what exactly are you wanting to know? It isn’t clear from your question. Please advise and I will answer it for you ASAP. I think I know what you are wanting but I don’t want to assume.... thank you

Answer:</h3>
- Can only be seen while looking through a lens
- May appear larger than the object
- Appears to come from behind the lens
<h3>
Explanation:</h3>
To answer this question we need to ask ourselves;
What is a virtual image?
- A virtual image is an image that can not be formed on a screen.
- It is formed by rays that appear to converge at a point.
What are the characteristics of a virtual image?
- A virtual image can only be seen while looking through lenses
- The image appear to come from behind the lens
- It may be larger than the object
- It can not be projected onto a screen.
- It is always upright
Answer:
Warm front
Explanation:
A warm front forms when a warm air mass pushes into a cooler air mass, shown in the image to the right (A). Warm fronts often bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds and storms. Warm fronts move more slowly than cold fronts because it is more difficult for the warm air to push the cold, dense air across the Earth's surface. Warm fronts often form on the east side of low-pressure systems where warmer air from the south is pushed north.
You will often see high clouds like cirrus, cirrostratus, and middle clouds like altostratus ahead of a warm front. These clouds form in the warm air that is high above the cool air. As the front passes over an area, the clouds become lower, and rain is likely. There can be thunderstorms around the warm front if the air is unstable.
On weather maps, the surface location of a warm front is represented by a solid red line with red, filled-in semicircles along it, like in the map on the right (B). The semicircles indicate the direction that the front is moving. They are on the side of the line where the front is moving. Notice on the map that temperatures at ground level are cooler in front of the front than behind it.
Explanation:
Entropy means the amount of randomness present within the molecules of the body of a substance.
Relation between entropy and microstate is as follows.
S = 
where, S = entropy
= Boltzmann constant
= number of microstates
This equation only holds good when the system is neither losing or gaining energy. And, in the given situation we assume that the system is neither gaining or losing energy.
Also, let us assume that = 1, and 
= 0.833
Therefore, change in entropy will be calculated as follows.
= 
= 
= 
or, = 
Thus, we can conclude that the entropy change for a particle in the given system is J/K particle.
