A rigid body of mass $m$ rotates about a fixed axis with angular velocity $\omega$. If a torque $\tau$ is applied for a time $\Delta t$, causing a change in angular velocity to $\omega + \Delta \omega$, what is the impulse of the torque in terms of its moment of inertia $I$?
Consider two particles of masses $m_1$ and $m_2$ connected by a massless rod of length $r$. They are rotating in a plane about a fixed point with an angular velocity $\omega$. If $m_1$ is at a distance $r_1$ from the pivot and $m_2$ is at a distance $r_2$ such that $r_1 + r_2 = r$, what is the ratio of their kinetic energies if the center of mass is at the pivot?
A sample of an ideal gas undergoes a reversible adiabatic expansion from an initial state ($P_1, V_1, T_1$) to a final state ($P_2, V_2, T_2$). If the gas has $\gamma = C_P/C_V$, which of the following expressions correctly relates the initial and final temperatures and volumes?
