Answer:
maybe alternator..generator..
We will first record its mass and then its volume by measuring its dimensions
then divide mass by volume and will get density of regular solid
The answer is unbalanced because the forces actually act on each other.
Answer:

Explanation:


If the sun considered as x=0 on the axis to put the center of the mass as a:

solve to r1


Now convert to coordinates centered on the center of mass. call the new coordinates x' and y' (we won't need y'). Now since in the sun centered coordinates the angular momentum was

where T = orbital period
then L'(x',y') = L(x) by conservation of angular momentum. So that means

Since
then
