Answer:

The angular acceleration is $\alpha = 3.235 \ rad/s ^2$

Explanation:

From the question we are told that

The moment of inertia is $I = 0.034\ kg \cdot m^2$

The net torque is $\tau = 0.11\ N \cdot m$

Generally the net torque is mathematically represented as

$\tau = I * \alpha$

Where $\alpha$ is the angular acceleration so

$\alpha = \frac{\tau }{I}$

substituting values

$\alpha = \frac{0.1 1}{ 0.034}$

$\alpha = 3.235 \ rad/s ^2$

Heat transferred - Work done = Internal Energy

Explanation:

If there is more heat transfer than the work done, the energy difference is called internal energy
The first law of thermodynamics equation is given as ΔU=Q−W where, ΔU = Internal energy; Q = Heat transfer; W = Work done
Heat = transfer of thermal energy between two bodies at different temperatures
Work = force used to transfer energy between a system and its surroundings
The First Law of Thermodynamics states - energy can be converted from one form to another with the interaction of heat, work and internal energy
Energy cannot be created nor destroyed
