Question #3b4ab

Answer 1

Bee moves along the circumference of the bowl.

Circumference`=2pir`
`=2xx22/7xx7=44cm`
Speed `=11cm cdot s^-1`

Distance moved in `4s="Speed"xx"Time"`
`=11xx4=44cm`

We see that in `4s` bee has completed one full circle of the rim of the bowl. It has returned to initial position.
`=>` Displacement `=0`

Answer 2

The thing to take away from this problem is that distance is a scalar, a quantity that has only magnitude. Displacement, on the other hand, is a vector, a quantity that has both magnitude and direction.

As was mentioned, since the bee ended up where it started, it's displacement is zero.
