It is b to use a telescope
Answer:
See explanation
Explanation:
The chlorination of benzene occurs in the presence of a Lewis acid. A Lewis acid is a compound that can accept a lone pair of electrons.
The first step in the chlorination of benzene is the formation of the ion Cl^+ which attacks the benzene ring.
This ion is formed when the Cl2 molecule undergoes heterolytic fission assisted by FeCl3 to yield FeCl4^- and Cl^+.
The Cl^+ electrophile now attacks the benzene ring to yield chlorobenzene.

Answer:
The kinetic increases by 48.84 %
Explanation:
The expression for the kinetic energy is:-
Where, m is the mass of the object
v is the velocity of the object
Let the new velocity is:- v'
v is increased by 22 %. Thus, v' = 1.22 v
So, the new kinetic energy is:-
<u>Thus, the kinetic increases by 48.84 %</u>
Answer: You could if you had a special fire letting out UV light, but if not, you'd probably get burned first.
Explanation:
Fire does emit UV, which causes tanning, but it also emits a lot of other wavelengths, including infrared which is primarily responsible for heating. If you build a really big fire, one that would emit enough UV to tan, it would also emit a huge amount of infrared which will burn you sooner than you getting a tan.
