Answer:
The correct answer is option a. 400J
Explanation:
Hello!
Let's solve this!
To know if the work is positive or negative we have to know the following:
The work is positive when the gas performs (expansion)
The work is negative when done outside on the gas (compression)
In this case the work is done by the gas, so it is positive.
The correct answer is option a. 400J

Answer:
The moment of inertia of the wheel is 0.593 kg-m².
Explanation:
Given that,
Force = 82.0 N
Radius r = 0.150 m
Angular speed = 12.8 rev/s
Time = 3.88 s
We need to calculate the torque
Using formula of torque
Now, The angular acceleration
We need to calculate the moment of inertia
Using relation between torque and moment of inertia
Hence, The moment of inertia of the wheel is 0.593 kg-m².
