Question

A 100-m long transmission cable is suspended between two towers. If the mass density is 2. 01 kg/m and the tension in the cable is 7. 30 × 10^3n. What is the speed of transverse waves on the cable?

Answer 1

The speed of transverse waves on the cable is 60.26 m/s.

Given,

μ=2.01kg/m, L=100m, T=$7. 30 * 10^3$N

Speed(v)=$\sqrt{\frac{T}{μ} }$=$\sqrt{\frac{7.3*10^{3} }{2.01} }$=60.26m/s

Speed

The speed of an object, sometimes known as "v" in daily speech and kinematics, is a scalar quantity that measures how much its position changes over time or how much it changes per unit of time. The distance traveled by an object during a time interval is equal to the duration of the interval divided by the object's speed, with the instantaneous speed being the upper limit of the average speed as the interval's duration becomes closer to zero. Velocity differs from speed.

Distance divided by time is the formula for measuring speed. A metre per second (m/s) is the metric unit of speed.
