For a wave pulse on a string to travel twice as fast, the string tension must be

1-Decreased to one fourth its initial value.
2-Increased by a factor of 4.
3-Not possible. The pulse speed is always the same.
4-Increased by a factor of 2.
5-Decreased to one half its initial value.

Sagot :

Option B;  A wave pulse on a string to travel twice as fast, the string tension must be 2-Increased by a factor of 4.

wave velocity is given by

v =2v.

T = 4T

As the pulling force transmitted axially by a string, rope, chain, or other similar object, or by each end of a rod, truss member, or other similar three-dimensional object, tension is defined; it can also be defined as the action-reaction pair of forces acting at each end of the aforementioned elements. Compression's opposite, tension, might exist.

When molecules or atoms are forced apart at the atomic level and accumulate potential energy while a restoring force is still present, the restoring force may produce what is also known as tension. Under such stress, each end of a string or rod might pull on the thing to which it is linked, releasing the tension and allowing the string or rod to return to its relaxed length.
