Answer:
The frequency is 
Explanation:
From the question we are told that
The frequency of the tuning fork is 
The beat period is 
Generally the beat frequency is mathematically represented as
The beat frequency is also represented mathematically as
Where 
is the frequency of the piano
So
Answer:
Fluid fricton goes to Static friction and sliding friction goes to rolling friction
Explanation:
Answer:
Qualitative, Quantitative, Qualitative, Quantitative, and Qualitative.
Explanation:
Answer:
Kinetic energy
Explanation:
When an apple falls from a tree it has to do with the energy from gravity. Gravity energy turns into kinetic energy once its in motion.
Sorry if im wrong
Highest fluid potential energy: answer A
Because the fluid is pushed upwards and potential energy is function of height. Since point A is the highest, there is the highest potential energy.
highest fluid pressure: answer C
This is because it is at the bottom where you have a hydrostatic pressure component
increasing fluid speed: answer B
This is because the section of the pipe is smaller and in order to have the same fluid flow rate the speed must increase
