Answer:a device for calibrating thermometers at the boiling point of water at a known height above sea level or for estimating height above sea level by finding the temperature at which water boils.
Explanation:
Here are the ones that I know about
and can think of just now:
-- wind
-- solar
-- nuclear
-- tidal
-- hydro
-- geothermal
-- biomass
The frequency of the wheel is the number of revolutions per second:
And now we can calculate the angular speed, which is given by:
in the clockwise direction.
Answer:
Centripetal force comes from the Latin, centrum = centre and petere=to seek. It acts perpendicular to the object path, towards the center of the curve. This results in change of the direction of the object's velocity but not in change of object's speed.
So only the first option is correct: It acts at a right angle to the object's motion and causes the object to constantly change direction.
