Calculate the distance to the Large Magellanic Cloud in kiloparsecs (kpc)ifit is approximately 163000 light years away. (Note: 1 kiloparsec = 1000 parsecs.)

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

i don't understand. explain it clearly

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
