Because it gives us the abilitity to find planets that have decent temperatures relative to earths temp so we can determine if the planet even has a possiblilty to sustain life hope this helps
Velocity is a speed AND a direction.
When you turn a corner, or go around a curve in the road, your
direction changes, but the reading on the dial doesn't change.
So it can't be showing velocity. It must be showing only speed.
That's probably a big part of the reason why it's called a speedometer
and not a velocimeter.
Answer:
White dwarf
Explanation:
The Hertzsprung-Russell Diagram shows the mass of stars, the color, temperature and their brightness.Stars that lie below the main sequence area such as the White dwarf have the smallest initial mass.A white dwarf star has a mass less than that of the Sun.
Explanation:
We have,
Height of object is 5 cm
Object distance from a convex lens is 18 cm
Focal length of convex lens is 10 cm
i.e. h = 5 cm
u = -18 cm
f = +10 cm
Let v is distance of the image from the lens. Using lens formula :
The magnification of lens is :
, h' is height of the image
h' = -5.00 cm (in three significant figures)
Explanation:
If there are more reactants than products, it is a synthesis reaction. If oxygen is a part of the reactant, it is a combustion reaction. If one ion replaces another, it is a single replacement reaction. If there are two compounds in a reactant where cations switch, it is a double replacement reaction.
