A convex mirror has focal length f. An object is placed at distance u from it. The image distance v is given by:

A metallic rod of length L and cross-sectional area A is heated by ΔT. If the rod is clamped at both ends and Young's modulus is Y, the thermal stress developed in the rod is:

A thin uniform circular ring of mass M and radius R has a moment of inertia I = MR² about an axis perpendicular to its plane passing through its center. The moment of inertia about a diameter is:

Two masses m₁ and m₂ (m₁ > m₂) are connected by a light inextensible string passing over a frictionless pulley. The system is released from rest. The tension in the string during the motion is:

Light of wavelength 600 nm is incident on a single slit of width 0.1 mm. The angle to the first minimum is approximately

An ideal gas undergoes an adiabatic compression. Its temperature:

A force F = (3x² + 2x) N acts on a particle moving along the x-axis. The work done in moving the particle from x = 1 m to x = 3 m is:

A cylindrical tank of cross-sectional area A has a small hole of area a at the bottom. The time taken to empty the tank from height H to zero is T₁. If the hole area is doubled to 2a, the new emptying time is T₂. The ratio T₁/T₂ is:
