A particle executes SHM with amplitude 5 cm and angular frequency 10 rad/s. The maximum acceleration of the particle is:

A nuclear reaction involves the fusion of two deuterium nuclei (²H) to form helium-3 (³He) and a neutron (¹n). If the masses are: m(²H) = 2.0141 u, m(³He) = 3.0160 u, m(n) = 1.0087 u, the energy released is approximately: (1 u = 931 MeV)

A long straight wire carries a current of 5 A. The magnitude of the magnetic field at a perpendicular distance of 10 cm from the wire is: (μ₀ = 4π × 10⁻⁷ T·m/A)

The root mean square speed of gas molecules at temperature T is proportional to:

A battery of emf 12 V and internal resistance 2 ohm is connected to a 4 ohm resistor. The current in the circuit is:

A gas undergoes an isothermal expansion at temperature T, doing 500 J of work on its surroundings. During the same process, the gas absorbs 200 J of heat. What is the change in internal energy of the gas?

A circuit consists of a 10 V battery connected in series with three resistors: R1 = 2 ohm, R2 = 3 ohm, and R3 = 5 ohm. The potential difference across R2 is:
