50Ω Resistance Unit, Max 7.0V Subject_Anatomy Six-piece 3-inch optical lens set

Six-piece 3-inch optical lens set combining three double-convex and three double-concave glass lenses at 200mm

with lengths varying by density to isolate the mass-volume-density relationship for student investigation

producing water jets of varying distances to show how pressure increases with depth in hydrostatics

delivering the continuous pressurized flow that lifts gliders off the rail for friction-free motion experiments

50Ω Resistance Unit, Max 7.0V Subject_Anatomy Six-piece 3-inch optical lens setLabeled terminal 50 ohm resistance unit at 7. 0V max in a plastic enclosure, providing the standard mid range value for current limiting LEDs and dropping resistors in student circuits.
