The hottest layer in Sun's atmosphere is the Corona.
The sun's atmosphere is composed of three main layers.
1. Photosphere- the lowest layer and closest in distance from the the sun's core. It has an average temperature of 5,800 degrees Kelvin. It usually appears granulated and bubbly, like a simmering pot of water.
2.Chromosphere- extends above the photosphere to about 2000 km. Its temperature is 4,500 - 10,000 degrees Kelvin.
3. Corona - outermost layer of the sun, extending several million kilometers outward from the chromosphere into space. The average temperature averages 2 million degrees Kelvin. It is thought the sun's magnetism is the reason that the corona is so hot.

Answer:
Sry but the question is not visible.......so plzz attach another image
So what you wanna do is take your two givens. 22 and 3. Now you wanna take 22 and divide that by 3. And that gives you 7.33. Now if your answer HAS to be a whole number it'll be 66.
Answer:
The focal length of the lens is 5.54 cm and the height of the image is -0.89 cm.
Explanation:
Given that,
Height of object h = 2 cm
Object distance u= -18 cm
Image distance v= 8 cm
We need to calculate the focal length of the lens
Using formula of lens
Where, f = focal length
Put the value into the formula
(II). We need to calculate the height of the image
Using formula of magnification
Put the value into the formula
Hence, The focal length of the lens is 5.54 cm and the height of the image is -0.89 cm.
