Used with 274500 Insulated cups to confirm Joule’s law. Plastic lid with hole for inserting a thermometer. Fitted with 2.2 ohm heating element connected to 2 telephone jack sockets.
Replacement test coupons for the Stress/Strain Apparatus.
Combines features that significantly improve the ease of setup, the durability of the Torsion Band and the quality of results. In the newer models the spheres are tungsten rather than lead.
Includes 80 experiments in mechanics, thermodynamics, waves, optics, electricity and magnetism. CD included.
Allows the students observation of velocity of drop rising in an electric field, then permits calculation of the force on the charge carried by the oil drop.
Replacement Spheres and collars for the Gravitational Torsion Balance (AP-8215A). Designed to convert to Tungsten while maintaining the proper large sphere dimensions.
