A chain is wrapped around a pulley and pulled with a force of 16.0N The pulley has a
radius of
0.20m. The pulley's rotational
speed increases from 0.0 to 17.0 rev/min in 5.00s. What is the moment
of inertia of pulley ?

v 16 .0×0.20=

Explanation:

42

17.0 x5.00= 85

85_42= 43

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
