Waves travel along a 100-m length of string which has a mass of 55 g and is held taut with a tension of 75 N. What is the speed of the waves?

Explanation:

The speed of the waves in a string is related with the tension and mass per unit length of the string, as follows:

First, we calculate the mass per unit length:

Now, we calculate the speed of the waves:

i think they are all correct

explanation:

they seem good

the higher the current the higher the mag field around it the higher the influence on the compass
