A star is a sphere composed of hydrogen and plasma. Red dwarfs are the coolest stars , also called M type of  stars. (The solution is Antares, a type M star). These cool stars are small stars in therms of their mass and have not enough mass to produce energy. That is the reason why they are the coolest.

Answer:

Antares, a type M star    

Explanation:

Stars are classified based in temperature using alphabets:

O, B, A, F, G, K, and M

Where, O represents a star having very high temperature. It would also be blue in color. (temperature about 41,000 K)

M represents a cool star having low temperature and red in color. (temperature about 3850 K)

Thus, Antares which is classified as a type M star would be the coolest.

A man has a mass of 70kg. Calculate his weight on earth where the gravitational strength is 10 N/kg​
maw [93]

Answer:

So the weight of the body is 700N

Explanation:

mass of the object=70kg

force of gravity=10N/kg

weight of the object=w-?

as we know that

weight=mass × force of gravity

weight=70kg × 10N/kg

WEIGHT OF THE BODY=700N

According to our theory of solar system formation, why do all the planets orbit the Sun in the same direction and in nearly the
11Alexandr11 [23.1K]

The laws of conservation of energy and conservation of angular momentum ensure that any rotating, collapsing cloud will end up as a spinning disk is the reason.

<h3>What is an Orbit?</h3>

This is defined as a curved path in space which is characterized by an object going round and round a planet, moon, or star.

In this scenario, all the planets orbit the Sun in the same direction and in nearly the same plane to ensure any rotating, collapsing cloud will end up as a spinning disk.
