berukuran jisim 100g setiap satu dengan 1 penggantung berukuran jisim 100 g.
Block Calorimeter - Copper & Aluminium
- Block Calorimeter can be used for the experimental determination of the specific heat capacity.
- have 2 holes in the middle to insert a immersion heater and thermometer.
Diode
A diode is a semiconductor device that essentially acts as a one-way switch for current. It allows current to flow easily in one direction, but severely restricts current from flowing in the opposite direction.
Mercury-in-glass thermometer
- Bebuli yang diperkuatkan, senggatan ditanda dengan dakwat kekal dan berlatar belakang enamel yang berwarna kuning. Julat bacaan – 10˚C hingga 110˚C.
- A thermometer is a device for measuring temperature. It are widely used in industrial, studies, medical and scientific research. Mercury-in-glass thermometer contain mercury and its accuracy will be better than alcohol thermometer.

Transverse and Longitudinal Wave Demonstration
This wave is called a transverse wave because the motion of the slinky is sideways to the motion along the slinky.
A longitudinal wave can be created in a slinky if the slinky is stretched out in a horizontal direction and the first coils of the slinky are vibrated horizontally.
Constantan Wire - 34 SWG; 32 SWG; 28 SWG; 20 SWG
Constantan wire is composed of Nickel
and Copper. It contains 60% of nickel and 40% copper. Constantan wire
are examples of ohmic conductors.
Sliding Rheostat Adjustable Resistance
A rheostat is a variable resistor, usually with three terminals. It is not a single terminal that can be connected to either positive or negative. It is basically a resistor, and as a resistor, either terminal can be connected to either side of the circuit since a resistor is not polar.
Digital Oscilloscope
Accuracy DC 0-1 A Ampere Analog Ammeter
- Ammeter disambung secara bersiri dalam litar.
- Kedudukan tanpa paralaks bagi mata ialah apabila anda tidak dapat melihat imej penunjuk dalam cermin di bawah skala.
DIAMOND Mechanical Stopwatch 60x1s
- Putarkan skru jam randek sebelum menggunakannya.
- Seboleh-bolehnya ukur sela masa yang lebih panjang.
- Rekodkan bacaan anda dengan kejituan +- 0.1 s.
To study resonance in an oscillating system
Resonance occurs when the natural frequency of a system corresponds to the frequency of the energy supplied.
