The pulse rate on a light straight string is V sqrt when a weight W is suspended from it (2V)

The correct answer is D

What the is physics' definition of speed, and how do you quantify it?

A distance's rate of change over time is used to calculate speed. It has a dimension of distance via time. The Vernier scales of speed is made up of the fundamental units of distance and time. The unit of speed in the metric system is meters per second.

Exactly what is speed?

What is considered speed? the rate at which an object's location changes in any direction. Speed is defined as the relationship between length and the time required to travel a distance. Speed is a scalar number because it has no magnitude and only a direction.
