Select the correct answer.
how does increasing the tension of a spring affect a wave on the spring?

a.
wave velocity increases
b.
wave velocity decreases
c.
wave amplitude increases
d.
wave amplitude decreases

A. the velocity of the wave increases

Explanation:

from the mathematical formular

where v is the velocity, f is frequency, T is tension, l is length or wavlenght and k is constant.

from the expression you can see that when the tension increases, the velocity will also increase.

for amplitude, tension has no effect on it.

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
