Aturntable that spins at a constant 74.0 rpm takes 3.10 s to reach this angular speed after it is turned on. find its angular acceleration (in rad/s2), assuming it to be constant, and the number of degrees it turns through while speeding up.

Explanation:

The angular acceleration is given by:

where

is the final angular speed

is the initial angular speed

t = 3.10 s is the time interval

Solving the equation,

Now we can find the angular displacement by using:

Substituting,

In degrees:

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat
