What is the period of a wave traveling 5 m/s if its wavelength is 20 m/s

Speed of wave is given as

Wavelength of the wave is given as

now from the formula of wave time period we can say

so it will have time period of T = 4 s

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
