Answer:
Step-by-step explanation:
Refer to physics equation , where is angular velocity.
Angular velocity's SI unit is rad/s. Convert rev/min to rad/s:
Now substitute and into :
Most of the new but cheaper sailboats I see that can be used out at sea usually cost 40-50k, but a pre-owned one would probably be 20-25k depending on the quality of the boat. Plus the price would depend on where you live.
Answer:
Alcohol
Step-by-step explanation:
Alcohol would be more suitable for making measurements in a -60 degree laboratory, since its boiling point is 78 degrees and its freezing point is -80 degrees, meaning alcohol will not freeze in a -60 degree environment.
Mercury on the other hand, has a freezing point of -39. Thus, it will freeze in a -60 degree environment, making it not suitable for use in this laboratory.
