Answer:
B. In the winter, when water use is low, precipitation exceeds evapotranspiration
Explanation:
A water budget can be seen as the relationship between the inflow and outflow of water through a specified region. It gives a general Idea of the relationship between the demand and supply of water in that region.
Evapotransipration is the loss of water from the soil through evaporation from the soil and other surfaces and by transpiration from plants, while precipitation refers to rain, snow, sleet, or hail that falls to the ground.
During winters due to the cold temperatures, the rate of water loss from the soil and from plants is much lower than the amount of precipitation which is on form of snow.
Snow covers most of the soil, freezing the soil water at the surface of the soil, making it difficult for evapotranspiration to occur. In addition to that, most deciduous trees shed their leaves during this period further reducing the total amount of transpiration in that region.
This makes option B correct
Answer:
Market risk premium.
Explanation:
The difference between average annual returns on common stocks and returns on long-term government bonds is called a market risk premium.
Basically, market risk premium is typically determined by taking the slope of a security market line (SML); which is used by economist as a graphical representation of the capital asset pricing model (CAPM).
Market premium risk is used to determine the quantitative measure of the extra return demanded by market participants for the increased risk.
Answer:
It means that the marginal cost of going to the movies is less than the marginal benefit of going to the movies.
Explanation:
If the student chooses to go to the movies, it means that he thinks he has less to lose when he foregoes studying for a test. Even though logically it may appear that the latter would be a better option, according to him, the 2 or so hours at the movies would provide an extra value like if he went with a family member who he cares about. That probably beats the cost of staying up late to revise for the test.
The answer is: 1990 - 2000
By this time period, more people realize that energy generated from hydroelectric power is much more sustainable compared to other alternatives since it mostly relied on renewable resources. Between this period of time, nations on average use 2000 - 2500 billion kwh from hydroelectric power.
Answer:
TVM=34,720*0.075/12 : [1-(1+0.075/12)^-48]
TVM=839.49
Explanation:
An=34,720
t=4 yrs , ---> n=48 (4*12)
j=7.5 %.---> i=0.075/12
m=12
* i=j/m
*n=mt
TVM=An*i : [1-(1+i)^-n]
TVM=34,720*0.075/12 : [1-(1+0.075/12)^-48]
TVM =839.49 (round two decimal)
