Decade Capacitance Box, Model F Graduations_Ungraduated transverse

transverse

providing dense uniform spheres for ramp-and-collision experiments where a heavier projectile is needed than the plastic marbles can provide

Compass mounted parallel to a current-carrying coil deflects against Earth's horizontal field

One-inch brass ball that threads onto a pendulum string as a heavier metal counterpart to aluminum or steel balls in mass-dependent periodic-motion investigations

Decade Capacitance Box, Model F Graduations_Ungraduated transverseUsed to substitute calibrated capacitance into AC circuits without rewiring, this decade box selects cascaded values for RC time constant, resonance, and frequency response student work.
