The human ear is most sensitive to sounds in the range of 2000 to 3000 Hz
Icing sugar has a larger surface area meaning smaller particles allowing it to dissolve faster
Answer:
Solution given;
load =600N
effort=?
load distance: 0.6m
effort distance;2.6m
we have
load *load distance :effort *effort distance
0.6*600=effort *2.6
360/2.6=effort
effort:138.46N

D because it has the lowest wavelength, meaning the wave is the longest. Its crest are more spaced out creating lower energy. The smaller distance between the crests equals the higher the sound. Creating higher energy.
I am 95% sure this is right. Very sorry if it isn't.
Hope it helps. ;3
That would be big fat no as far as i am aware
