What type of star has an absolute brightness of 1 and a surface temperature of around 7,500 °C?
The HR diagram is shown with Absolute Brightness on the y axis from negative four to six and Surface Temperature on the x-axis from 40,000 to 2,500 degrees Celsius. There are several dots plotted between four and six absolute brightness and 10,000 to 2,500 degrees Celsius labeled Supergiants. There are several dots plotted between 1.5 and three absolute brightness and 7,500 to 2,500 degrees Celsius labeled Giants. There are several dots plotted between negative four and negative two absolute brightness and 30,000 to 7,500 degrees Celsius labeled Dwarfs. Down the middle, there are several dots plotted diagonally from ordered pair 40,000 and five down to 2,500 and negative three labeled Main Sequence.
Select one:
a. Supergiant
b. Giant
c. Main sequence
d. Dwarf
Answer:
Main Sequence Stars or C
Explanation:
our star, the sun, being a main Sequence Star with an absolute brightness of 1 with a temp of about t 7500 °C gave me this answer

Jean-Paul is racing in the Tour de France bicycle race. He is moving along rapidly at a speed of 15 kilometers per hour. Suddenly, a strong wind begins to blow into his face. Jean-Paul cannot exert any more force on the pedals. What will happen to Jean-Paul's speed while the wind continues to blow against him?
If the air resist his motion continuously, speed of Jean - Paul get reduced until he could apply an equal force in opposite direction to the wind.
What is force?Force is an external agent acting on an object to change its state of motion or rest or to deform it. There are various kinds of force such as gravitational force, magnetic force, frictional force.
If there are two different forces acting from the same direction will add up together and the net force will be the sum of their magnitudes. If they are in opposite direction, they will balance each other will decreases the displacement.
Hence, the force from the air resistance will balance the force exerted by Jean Paul and his speed will decrease until he apply a greater force forwards.
