Answer:
frequency
Explanation:
The phenomenon of apparent change in frequency due to the relation motion between the source and the observer is called Doppler's effect.
So, when we move farther, the frequency of sound decreases. The formula of the Doppler's effect is
where, v is the velocity of sound, vs is the velocity of source and vo is the velocity of observer, f is the true frequency. f' is the apparent frequency.

Cell is the
fundamental unit of life. It is the component of every living organism,
creature and being in the biotic environment. Thus, each of this organisms like
this panda have cells, which is grouped together to form tissues, and when tissues
form together they form the organs and then the organs systems and entirely, as
one organism. An entire organism then is what compose species. This hierarchical
structure is what every organism is totally composed of. But without the cell –these
different types of cells. There would no life.
Answer:
b) 252 Hz or 260 Hz
c) 0.25 s
Explanation:
b) The frequency of the beats is 4 Hz, and one tuning fork has a frequency of 256 Hz. Therefore, the second tuning fork is either 4 Hz lower or 4 Hz higher.
f = 252 Hz or 260 Hz
c) Period is the inverse of frequency.
T = 1/f
T = 1 / (4 Hz)
T = 0.25 s
Answer:
The value of pressure inside the cylinder is 18.68 K Pa.
Explanation:
Given data
Height h = 0.14 m
Density 
= 13600 
We know that
Pressure inside the cylinder is given by the formula
P = g h ------- (1)
here
= density of fluid = 13600
g = acceleration due to gravity = 9.81 
h = height of the cylinder = 0.14 m
Put all the values in above equation
P = 13600 × 9.81 × 0.14
P = 18678.24 Pa
P = 18.68 K Pa
Therefore the value of pressure inside the cylinder is 18.68 K Pa
