Answer:
the seed of the sound in the air is 343.3 m/s
Explanation:
The computation of the speed of the sound in the air is shown below:
As we know that
Speed = Distance divided by Time
So, here speed be 515m
And, the time is 1.50 second
So, the speed of the sound is
= 515m divided by 1.50 seconds
= 343.3 m/s
hence, the speed of the sound in the air is 343.3 m/s
Many factors including Decomposition, energy conversion, littering, erosion, etc.
Explanation:
Given parameters:
Frequency = 500Hz
Unknown:
a. Period of rotation
b. Time required to complete 7 rotation
Solution:
The period of rotation is the time taken to complete a turn.
P =
P is the period
t is the time
n is the number of turns
Period is the inverse of frequency;
P = = 0.002s
b.
Time required to complete 7 rotation;
P =
t = P x n
t is the time
P is the period
n is the number of rotations
t = 0.002 x 7 = 0.014s
