An 89 kg person climbs up a uniform 13 kg ladder. The ladder is 5.9 m long; its lower end rests on a rough horizontal floor (static friction coefficient 0.26) while its upper end rests against a frictionless vertical wall. The angle between the ladder and the horizontal is 52◦. Let d denote the climbing person's distance from the bottom of the ladder (see the above diagram). When the person climbs too far (d > dmax), the ladder slips and falls down (kaboom!). Calculate the maximal distance dmax the person will reach before the ladder slips. The acceleration of gravity is 9.8 m/s2.

Answer:
It can be concluded that groombrige 34 b is more luminous than centauri c since they have the same apparent magnitude.
Explanation:
The apparent magnitude is the brightness that a star appears to have as seen from the earth.
This can variate as a consequence of the distance or radius of the star.
for example, if one of two stars has a bigger radius that a second one, the free mean path of the photons will be higher than in the smaller one, so the bigger one will be more luminous.
In the case of the distance, if for example, two motorbikes with its lights on are approaching an observer, but one of the motorbikes is at a greater distance, it will appear that is light is dimmer compared to the one that is closer. Even if both emit the same amount of light per unit of time.
Therefore, it can be concluded that groombrige 34 b is more luminous than centauri c since they have the same apparent magnitude.
