Answer:
Distance in kilometre = 4.242 x 10¹² km
Explanation:
Given:
Distance of Proxima Centauri = 4.242 light years
Find:
Distance in kilometre
Computation:
1 light year = 10,000,000,000,000 km
So,
4.242 light years = 4.242 x 10,000,000,000,000
Distance in kilometre = 4.242 x 10¹² km
Answer:
a). Nepthalene is a D2h molecule because it has 3 C2 axes which are perpendicular and it has a mirror plane which is horizontal. Moreover C2 is taken as principal axis.
b). 1,8-dichloronaphthalene is a C2v molecule beccause it has 1 C2 axis, two rings are joined by the C-C bond and it also has two mirro planes.
c). 1,5-dichloronaphthalene is a C2h molecule because it has only 1 C2 axis which is pependicular to the plane, it has an inversion center and also a mirror plane which is horizontal in position.
d). 1,2-dichloronaphthalene is a Cs molecule because it has only a mirror plane.

Answer:
Solar energy causes evaporation; uneven heating of the Earth causes air masses to move; Coriolis forces help storms to take shape; and gravity makes rivers flow downhill. Another relevant factor is the high heat capacity (or specific heat) of water.
