1. The Marquis CST reagent is applied to an unknown drug and the
solution turns green. Next, Cobalt Thiocyanate reagent is applied
and the solution turns reddish-orange. For the same unknown drug,
Mecke’s reagent turns the solution a greenish black color.

1. Dynamics and artificial gravity.
The space station has two thrusters pointed in opposite
directions. They operate by expelling propellant at high speed. The
effect is that there is a force of magnitude F0 on the
two ends of the space station in opposite directions, which causes
the entire object to start rotating. The thrusters will stop firing
when the artificial gravity created on the space station (described
below) reaches the required value.
Upward force, magnitude F0
Downward force, magnitude...
