Measurement of the distance‚ the thickness and the radius of curvature Purpose : To learn how to use vernier caliper‚ micrometer and spherometer to measure internal and external diameters of a pipe‚the thickness of a copper rods‚ and the radius of curvature of spherical lenses. 1) Vernier caliper: As shown in Fig. 1 the main fixed scale in the vernier caliper has 1 mm gradations while th sliding scale (vernier scale) has 0.05 mm gradations. The smallest division of vernier scale is called

Determine what factors make a hot air balloon or a helium balloon float Student Instructions: 1. Why does a hot air balloon float even though it is so heavy? Hot air balloons float because the buoyancy force of the hot air is more that the

Height of Ball Drop v/s The Depth of the Crater | By Tejas Shah‚ IBDP Year 1 | | | | | | | * Aim- To find the relationship between the depth of crater and the height from which it is dropped. * Research Question- Does the height from where the ball is released affect the depth of the crater. * Hypothesis- If we increase the height of the drop of the ball; the depth of the crater would increase. This is because as there is loss in potential energy subsequently there
