Firdavs [7]3 years ago
8 0
Hey there!

1.) Without the atmosphere, average temperature on Earth would be freezing! Below zero to be exact!

2.) The atmosphere protects us and animals from dangerous radiation from the Sun. Ultraviolet radiation is basically invisible rays of energy created by the sun.

3.) Also, the atmosphere provides oxygen for humans and animals to breathe and C02 (Carbon dioxide) for plants.

4.) And lastly, the atmosphere protects us from objects coming towards the earth.

Hope this helps!

Example of limits that you may have for a teen is reducing their screen time while an example of limits for toddlers is correcting their junk eating habits. Teens should have a rigid limit so as to enable them do the right things at all times due to their strong emotions.

melomori [17]

Answer:

a=0.0947mm

Explanation:

Given data

λ=680nm

L=5.5m

ω=7.9cm=0.079m

To find

Width of slit a

Solution

As the single slit of width a has a bright central maximum of width:

ω=2λL/a

a=2λL/ω

Substitute the given values

So

a=\frac{2*680*10^{-9}m*5.5m}{0.079m} \\a=9.47*10^{-5}m\\or\\a=0.0947mm

Nadusha1986 [10]

Answer:

About 46 billion light years Because space expands so what we didn’t see before is what we could see now.
