If the string is 7.6 m long, has a mass of 34 g , and is pulled taut with a tension of 15 N, how much time does it take for a wave to travel from one end of the string to the other

The wave takes 0.132 seconds to travel from one end of the string to the other.

Explanation:

The velocity of a transversal wave () travelling through a string pulled on both ends is determined by this formula:

Where:

- Tension, measured in newtons.

- Length of the string, measured in meters.

- Mass of the string, measured in meters.

Given that , and , the velocity of the tranversal wave is:

Since speed of transversal waves through material are constant, the time required () to travel from one end of the string to the other is described by the following kinematic equation:

If and , then:

The wave takes 0.132 seconds to travel from one end of the string to the other.

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.

i believe the answer would be:

d. violin, clarinet, french horn, and tuba
