Newton's first law;
"An object in motion stays in motion, an object at rest stays at rest , an object in space stays in space unless an unbalanced force acts on it "
Not so sure of the law
Answer:
Explanation:
Given
Two Fundamental frequencies are 400 Hz and 800 Hz
Each Pipe has same length L
Fundamental frequency corresponding to pipe with both side open
where v=velocity of sound
Fundamental frequency corresponding to pipe with one side open and other side close
we can see that fundamental frequency of both side open pipe is twice of second pipe
so 800 Hz frequency will correspond to both side open pipe
Answer:
95 feet
Explanation:
We have given that 4 boards are of so total number of feet of 4 boards =
Two board are of so total number of feet of two board
And two boards are of so total feet
So total height of all boards = 58.5+23.5+13=95 feet
