Respond to the following questions with complete ideas.
1. A person gets a haircut twice per month. (A) What is the frequency of haircuts, and (B) what is the associated period of haircuts?
2. Due to changing conditions of the medium, the speed of a wave doubles, but its frequency remains the same. How does the wavelength of the wave change (if it does change)?

Hi I need help.I'll rate the work. It's due in 15 minutes. When you turn down the volume on the TV, the sound gets quieter. What can be said about the sound waves in this scenario? (Outcome 1) Question 14 options: 1) The wavelength has decreased 2) The amplitude has decreased 3) The frequency has decreased 4) The period has decreased For small amplitudes, how does increasing the length of the string change the period of a simple pendulum?

A wave pulse travels down a slinky. The mass of the slinky is m = 0.94 kg and is initially stretched to a length L = 7.4 m. The wave pulse has an amplitude of A = 0.23 m and takes t = 0.412 s to travel down the stretched length of the slinky. The frequency of the wave pulse is f = 0.45 Hz. 3)What is the average speed of a piece of the slinky as a complete wave...
