The perceived pitch of a tone is largely determined by its frequency
<h3>
What is frequency ?</h3>
The frequency of a repeated event is its number of instances per unit of time. In some cases, it is also referred to as temporal frequency or ordinary frequency to underline differences with spatial and angular frequencies, respectively. One (event) per second is equal to one hertz (Hz), which is how frequency is stated.
The period is the reciprocal of the frequency since it is the length of time for one cycle in a repeating occurrence. If a heart beats 120 times per minute (2 hertz), for instance, its period, T—the space between beats—is half a second. In science and engineering, frequency is a crucial metric for describing the temporal rate of change seen in oscillatory systems.

#SPJ4
Answer:
15
Explanation:
0.15 is a decimal place after a 0, whereas the 15 is a whole number
Yep, uh-huh, indeed, indubitably, and you better believe it.
The ball did accelerate.
Acceleration means any one of these:
-- speeding up
-- slowing down
-- changing direction .
The direction of the ball changed from east to west.
That's acceleration right there.
_____________________________________
Acceleration means any change of velocity.
Velocity is speed and direction.
The velocity of the ball changed from (40 km/hr east) to (40 km/hr west).
The change in velocity was 80 km/hr to the west.
Answer:
a) W=12166.20876 J
b) U= -12166.20876 J
Explanation:
No. of moles, n = 8.41
Change of temperature, ΔT = T1 - T2
= 395 - 279
= 116 K
For monatomic gas, γ = 5/3
γ -1 = 2 /3
Solution:
(a)
Work done,
plugging values we get
Ans:
12166.20876 J
Work done, W = + 12166.20876 J
(b)
From first law of thermodynamics, dQ = U + W
but, dQ = 0
( adiabatic process)
Hence, U = - W
= - 12166.20876 J
Ans:
Change in internal energy, U = - 12166.20876 J
Physical property, that means that it is not transpaerent, and can touch
