Answer:
ten octaves
Explanation:
Answer. One octave, corresponding to a halving of the upper frequency limit. Although human hearing covers a range of, say, ten octaves at best, seven of these octaves cover the bottom eighth of the range, from 20 Hz up to 2500 Hz, which corresponds roughly to the pitch range from E♭0 to E♭7 (Figure 26).
Answer:
Final volume is equal to 0.52 L
Explanation:
We have given initially the volume is equal to 
Let the initial pressure is 
At constant temperature 
, here 
is initial pressure and initial volume respectively and 
is final pressure and final volume respectively
Now pressure is doubled so final pressure 
So 
So final volume is equal to 0.52 L
Newton's second law is stated as:
F=ma,
a = (7-4)/1.5 = 2 m/s^2 (it is a deceleration due to impact with floor. And thus the ball exerts force on the floor).
Therefore,
F= 0.3*2 = 0.6 N
Answer: Acceleration is a measure of how fast velocity changes. Acceleration is the change of velocity divided by the change of time. Acceleration is a vector, and therefore includes both a size and a direction. In short, acceleration is the rate at which speed changes.
