Leuchtkraft von ähnlich hellen Sternen

About points...

We associate a certain number of points with each exercise.
When you click an exercise into a collection, this number will be taken as points for the exercise, kind of "by default".
But once the exercise is on the collection, you can edit the number of points for the exercise in the collection independently, without any effect on "points by default" as represented by the number here.

That being said... How many "default points" should you associate with an exercise upon creation?
As with difficulty, there is no straight forward and generally accepted way.
But as a guideline, we tend to give as many points by default as there are mathematical steps to do in the exercise.
Again, very vague... But the number should kind of represent the "work" required.

About difficulty...

We associate a certain difficulty with each exercise.
When you click an exercise into a collection, this number will be taken as difficulty for the exercise, kind of "by default".
But once the exercise is on the collection, you can edit its difficulty in the collection independently, without any effect on the "difficulty by default" here.
Why we use chess pieces? Well... we like chess, we like playing around with \(\LaTeX\)-fonts, we wanted symbols that need less space than six stars in a table-column... But in your layouts, you are of course free to indicate the difficulty of the exercise the way you want.

That being said... How "difficult" is an exercise? It depends on many factors, like what was being taught etc.
In physics exercises, we try to follow this pattern:

Level 1 - One formula (one you would find in a reference book) is enough to solve the exercise. Example exercise

Level 2 - Two formulas are needed, it's possible to compute an "in-between" solution, i.e. no algebraic equation needed. Example exercise

Level 3 - "Chain-computations" like on level 2, but 3+ calculations. Still, no equations, i.e. you are not forced to solve it in an algebraic manner. Example exercise

Level 4 - Exercise needs to be solved by algebraic equations, not possible to calculate numerical "in-between" results. Example exercise

Level 5 -
Level 6 -

Exercise:
Die Sterne Lalande maO und Lacaille mbO erscheinen von der Erde aus ähnlich hell. Sie befinden sich in einer Entfernung von raO bzw. rbO von der Erde. Berechnen Sie das Verhältnis der beiden Leuchtkräfte.

Solution:
Die Strahlungsensitäten für die beiden Sterne können ausgedrückt werden als S_ fracL_pi r_^ S_ fracL_pi r_^ Für die Differnez der scheinbaren Helligkeiten folgt dann m_-m_ -frac leftlogfracS_S_W-logfracS_S_Wright -fraclogfracS_S_ -frac logleftfracL_L_ leftfracr_r_right^right Aufgelöst nach dem Verhältnis der Leuchtkräfte ergibt sich fracL_L_ ratioF leftfracraXrbXright^ times ^- maX-mbX/ resultratioP Die Leuchtkraft des von der Erde aus helleren aber weniger weit entfernten Lalande ist also deutlich kleiner als diejenige von Lacaille .
