This list of apparatus is suitable for two common physics experiments:

Here are the experiments that can be performed with the given apparatus:

Q1
This list of apparatus is suitable for two common physics experiments:

• Investigation of Hooke's Law and/or Simple Harmonic Motion (SHM) of a spring-mass system. The two identical spiral springs, masses, metre rule, and stopwatch are key for this.
• Investigation of Simple Harmonic Motion (SHM) of a simple pendulum. The pendulum bob, thread, retort stands, and stopwatch are used for this.

Q2
This list of apparatus is primarily suitable for experiments involving heat energy:

• Determination of the specific heat capacity of water or Investigation of heating/cooling curves. The two beakers, water, source of heat, stirrers, two thermometers, and stopwatch are essential for these experiments. The measuring cylinder is used to measure the volume of water. The pendulum bob and thread are not typically used in these heat experiments.

Q3
This list of apparatus is ideal for experiments in electricity:

• Investigation of the factors affecting the resistance of a wire (length and cross-sectional area/resistivity) and/or Verification of Ohm's Law. The cell, rheostat, voltmeter, milliammeter, connecting wires, key/switch, and the two Constantan wires of different gauges are used to set up a circuit to measure current and voltage. The micrometer screw gauge is used to measure the diameter of the wires to determine their cross-sectional area. The standard resistor $R_x$ can be used for comparison or as part of the circuit.
