What is the approximate absolute brightness and temperature of the dwarf star labeled A What is the approximate absolute brightness and temperature of the main sequence star labeled B?
What is the approximate absolute brightness and temperature of the giant star labeled C?
What type of star has an absolute brightness of 5 and a surface temperature less than 2,500 °C?

The approximate absolute brightness is 10,000 and the temperature is 22,000 of the main sequence star.

The approximate absolute brightness is 100-1,000 and the temperature of the giant star is 22,000.

The answer is supergiants.

Explanation:

Hope u do good :)

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
