An ice skater has a moment of inertia of 1.7kgm^2 and is spinning at 16rad/s. The ice skater draws her arms in reducing her moment of inertia to 1.4kgm^2. What is her new rotation rate

Ithink the answer is a

So are u adding some additional catalyst

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
