Answer:
10
Explanation:
This is tough. The last number 0.2 has only one significant figure. So while the sum of all the numbers is 12.3, you must only leave one sig figure. Rounding to the tenths gives 10.
Incomplete question.The complete question is here
An energy storage system based on a flywheel (a rotating disk) can store a maximum of 4.1 MJ when the flywheel is rotating at 14000 revolutions per minute.What is the moment of inertia of the flywheel?
Answer:
Moment of inertia=3.82 kg.m²
Explanation:
Given data
Energy E=4.1 MJ=4.1×10⁶J
Angular speed ω= 14000 rev/min= 14000×2π/60=1465.3 rad/s
To find
Moment of Inertia
Solution
A rotating flywheel must store its energy as kinetic energy
Let I be moment of inertia of the flywheel.We Know
