Awave on a string is described by d(x, t)= (2.00cm)sin[(12.57rad/m)x−(638rad/s )t], where x is in m and t is in s. the linear density of the string is 5.00g/m. what is the string tension? what is the maximum displacement of a point on the string? what is the maximum speed of a point on the string?

Answer : The string tension is

The maximum displacement is 0.02 m

The maximum speed is

Explanation :

Given that,

D(x,t) = (2.00 cm) sin [(12.57rad/m)x - (638rad/s)t]

Where, x is in m and t is in sec.

Linear density of the string = 5.00 g/m

We know that,

Velocity of the wave

Now, the string tension

The maximum displacement is 0.02 m

The maximum speed  

Hence, this is the required solution.

not too sure thinking it will always be directed towards the centre of the earth. could be wrong not sure

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
