Answer:
Her real salary has fallen and her nominal salary has risen. The correct option is C
Explanation:
NOMINAL SALARY is defined as the actual amount of money paid to a worker as compensation for work done monthly.
REAL SALARY or wages is defined as the quantity of goods and services an individual can purchase from a monthly income. Therefore it is affected by an increase or decrease in the general price level in an economy( inflation). For instance, if an individual nominal wage is increased by 10% and inflation is 0%( that is, there was no increase in price of goods in the market) then the individuals real wage is increased by 10% too. But if inflation is 10%, then the real wage will be 0% ( meaning the inflation is rising at the same rate with the nominal wage increase).
In the case of the professor, she had $200 increase in her monthly nominal wage and she can buy fewer number of goods and services than she bought last year(increased inflation). Therefore her real salary has fallen because even with the $200 increase, she couldn't buy her usual quantity of goods.
Answer:
a) 30.84m/s
b) 348.32Hz
c) 32.34m/s
d) 289.69Hz
Explanation:
a) If 1 mile=1609,34m, and 1 hour=3600 seconds, then 69mph=69*1609.34m/3600s=30.84m/s
b) Based on Doppler effect:
/*I will take as positive direction the vector */
c)
d)
Answer:
9.97sec
Explanation:
To solve for the period we can derive the formula as follows
ω=2πf
ω=2π/T
v=rω
v=2πr/T
T=2πr/v
T=9.97sec
Answer:
Option D
Explanation:
In order to maintain homeostasis, a function is to be performed that leads to functional normality of the body and its organs.
Here, the death of cells is affecting the homeostasis hence in order to restore homeostasis the remaining cells must divide at higher pace so that they can replenish the lost cells and their functions.
Hence, option D is correct
