Two children are sending signals along a cord of total mass 0.45 kg tied between tin cans with a tension of 33 n . it takes the vibrations in the string 0.51 s to go from one child to the other. a. how far apart are the children? b. express your answer using two significant figures.

Explanation:

Given:

Tension in the string,

mass of the string,

time taken to transmit the sound,

We have the relation of the given with velocity 'v' as:

................................(1)

where:

= linear mass density of the string=

we know:

where:

length of the string

Putting the corresponding values in the eq. (1)

answer: a. same unit

explanation:

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
