Answer:
Explanation:
Given
mass of disk 
diameter of disc 
Force applied 
Now this force will Produce a torque of magnitude
And Torque is given Product of moment of inertia and angular acceleration 
Moment of inertia for Disc 
Answer:
Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in cities. When ozone forms air pollution, it's also called smog.
Speed=distance/time
distance = 10,000 m
time= 27 min 30.42s but we need to convert that completely to seconds
(27x60)+30.42= 1650.12 rounded to 1650
speed=10,000/1650.12
speed=6.059063
Because when we do sig dig we round to the least number of digits we would round to 4 because 1650.12 gets rounded to 1650
so 6.059 m/s
