3) The value of G was experimentally determined in 1798 by Lord Henry Cavendish
using a torsion scale.
The equipment he used included a light source, a 2 feet rod. Two small spheres were
attached to the ends of the rod and then were hung by the a wire.
1) This statement is incorrect as a car at rest has no net force acting upon it and it may have opposing
forces that cancel each other out.
2) You tend to move keep moving forward even though the bus is slowing down. This is because of the
Question: How does changing the amplitude and/or frequency affect the wave speed?
Hypothesis: It is hypothesized that the amplitude has no effect on wave speed whereas
decreasing or increasing the frequency will reduce or increase the wave speed respectiv

1982B1. The first 10 meters of a 100-meter dash are covered in 2 seconds by a sprinter who starts from
rest and accelerates with a constant acceleration. The remaining 90 meters are run with the same velocity
the sprinter had after 2 seconds.
