Apotter's wheel moves uniformly from rest to an angular speed of 0.20 rev/s in 32.0 s. (a) find its angular acceleration in radians per second per second. rad/s2 (b) would doubling the angular acceleration during the given period have doubled final angular speed?

a. The wheel accelerates uniformly, so its constant acceleration is equal to the average acceleration:

b. Yes. Since

then multiplying by 2 means we double the change in angular speed, but the wheel starts from rest so only the final angular speed gets doubled.

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 ! : )
