Answer:
The speed of the car is 67.77 m/s and it is moving away from the observer.
Explanation:
The apparent frequency is given as
![f' = f\dfrac{ [v - vo]}{ [v - vs]}](https://tex.z-dn.net/?f=f%27%20%3D%20f%5Cdfrac%7B%20%5Bv%20-%20vo%5D%7D%7B%20%5Bv%20-%20vs%5D%7D)
Here
o is the observer
s is the source which is car
v is the speed of sound = 343 m/s
f = true frequency emitted by the car (when stationary)
f ' = 0.835 f
so
![f' = f\dfrac{ [v - vo]}{ [v - vs]}\\0.835 f= f\dfrac{ [v - vo]}{ [v - vs]}\\0.835 = \dfrac{ [343 - 0]}{ [343 - vs]}\\0.835=\frac{343}{343-x}\\x=-67.77 m/s](https://tex.z-dn.net/?f=f%27%20%3D%20f%5Cdfrac%7B%20%5Bv%20-%20vo%5D%7D%7B%20%5Bv%20-%20vs%5D%7D%5C%5C0.835%20f%3D%20f%5Cdfrac%7B%20%5Bv%20-%20vo%5D%7D%7B%20%5Bv%20-%20vs%5D%7D%5C%5C0.835%20%3D%20%5Cdfrac%7B%20%5B343%20-%200%5D%7D%7B%20%5B343%20-%20vs%5D%7D%5C%5C0.835%3D%5Cfrac%7B343%7D%7B343-x%7D%5C%5Cx%3D-67.77%20m%2Fs)
The speed of the car is 67.77 m/s and it is moving away from the observer.
This is known as <u>market penetration-</u> instead of expanding his market to new customers or products he is doing a deeper development of the customers he already has to increase loyalty and sales.
Answer:
a. Demographic
Explanation:
In demographic segmentation market is segmented on the basis of variables like age, gender, family size, marital status, occupation, religion, income, employment etc.
Therefore, Demographic segmentation is the most common basis of consumer market segmentation because these segments are easy to define and usually easy to reach.
Prices can achieve the rationing function when prices are inflexible
.
Option B
<u>Explanation:
</u>
Prices can be rationed because prices are inflexible.
The proposal that certain prices slowly adjust to market deficiencies or surpluses
This is most critical for short-term and short-term global market research macroeconomic behavior. The positive trend of the short term allocative efficiency curve is largely because of inflexible markets (also referred to as static prices or sticky costs).
In commodity markets, prices are likely to become the most inflexible, particularly on the labor market as well as the least inflexible, with the commodity markets sliding between the two.
Answer:
E) 51 days
Explanation:
Calculation of length of the cash cycle after the changes.
As given:
Current cash cycle = 51 days.
Decreases its receivables period by 3 days
Increases its inventory period by 4 days.
Increases its payables period by 1 day.
Hence,
Cash cycle = 51 days - 3 days + 4 days- 1 day
Cash cycle = 51 day
Therefore the cash cycle after the changes will be 51 days
