Frequency refers to the number of wavelengths that pass a fixed point in a minute. true or false
Answer:True
<h3><u>Answer</u></h3>
- Distance is equal to the Total Distance covered by a body, from the initial till the final point

- Displacement is equal to the shortest distance between two points.
- So we known that Distance can only be equal to or greater than the displacement and can never be shorter than the displacement.
- This is just common sense how can anything be shorter than the shortest path itself. But it can be equal to the shortest path

☯ Distance is a scalar quantity and has only magnitude but no direction.
☯ Displacement is a vector quantity and has both magnitude and direction.
☯ Distance can only have +ve values whereas displacement can be +ve, -ve or even be zero.
The rod transferred negatively charged particle to the metal sphere. The rod becomes less negatively charged than it was originally (originally it was charged to -21 nc, now it has -8, and -8>-21), so it must have moved 13 nc of negative charge to the sphere.
