Answer:
Step-by-step explanation:
(9+(15*15))+7=241
Answer:5/8
Step-by-step explanation:
its more then 3/8
To answer the problem we would be using the formula:v=λ*f
where v=343 m/s
length of standing wave
λ=2*L=1.6m (since both of the ends are open),
L=80.0cm =0.8m; but we are going to rearrange it.
Therefore fundamental frequency is:
f=v/λ
= 343/(2*0.8)
=214.375 Hz
Answer:
2a (blue)
2b (pink/purple)
3b (light blue)
4a (red)
4a (green)
6a (yellow)
2a (purple)
2a+2b (orange)
6a (pink)
4a-b (pinkk)
4a-2b (purple)
6a (green)
Step-by-step explanation:
2 right triangles (2a) make a square
4 right triangles (4a) make a rectangle
2 right triangles (2a) make a bigger triangle
This alone can help with most of them by combining these together and adding/removing semicircles.
Answer will be 1 or 20+14 root 2/1+11 root 2
