Answer:
Option D; WATER HAS A LARGE HEAT CAPACITY.
Explanation:
Heat capacity is the amount of energy required to raise the temperature of a substance by 1°C. This activity demonstrates that water has a higher heat capacity than water.
A large body of water has a higher heat capacity than land, meaning it takes more energy to warm and cool the temperature of water.
Everyday, the land heats much faster than the sea and every night the land cools faster. When the land heats up, the air above it heats up as well. On the other hand, the ocean heats up and cools down relatively slowly. Therefore, areas near the ocean generally stay cooler during the day and have a more moderate temperature range than inland areas.
The characteristic of water that accounts for the fact that coastal regions do not experience such large temperature variations as landlocked areas is that WATER HAS A LARGE HEAT CAPACITY.
Answer:
The expected real value (in terms of January 1, 2009, dollars) of the depreciation charge in year 2013 will be $1,958,815.416.
Explanation:
It is expected that the value of the dollar in the German market will fall at the same rate as that of the real market value of the dollar when we envisage the exchange rate will remain the same. Thus the depreciation of the tax write-off in terms of its real value in dollars will fall at 5% every year from 2009 to 2013.
Therefore, at a tax rate of 50% in Germany, a $2.5 million charge on depreciation on the investment of $5 million will result in 2013.
To calculate the real value of the dollar at an inflation of 5% yearly in 2013
When the tax rate in German is 50%, then charges of depreciation of $5 million will equal4$2.5 million in 2013 dollars. When the dollar's real value of this write-off is declining due to the inflation at 5% annually, the real value in 2013 will be calculated as:
Given: $2,500,000 (P/F , 5%, 5years)
; 0.78356 (factor for calculating the amount to be recieved after 5years)
= $2,500,000 * 0.78356
= $1,958,815.416
Answer:
Total cost of operating the video store is $110,000
Explanation:
You decided to leave your job and operate a video rental store in the office space you inherited. You would not received the annually income from your job and rent commercial real estate.
Total income lost = $55,000 + $25,000 = $80,000
Total cost of operating the video store = Total income you lost + total costs for video purchases, utilities, taxes, and supplies = $80,000 + $30,000 = $110,000
Answer:
$14038
Explanation:
The company has marginal revenue R'(t) = 
. Therefore its revenue R(t) is given as;
R(t) = ∫R'(t)
R(t)= ∫ dt = + c
R(t) = + c
But R(0) = 0, therefore:
R(0) = 
+ c = 0
+ c = 0
100 + c =0
c = -100
Also the marginal cost per day is given by C'(t) = 140 - 0.3t
C'(t) = 140 - 0.3t
C(t) = ∫C(t) = ∫ (140 - 0.3t) dt = 140t - (0.3/2) t² + C
But C(0) = 0
C(0) = 140 (0) - (0.3/2)(0)² + c = 0
c = 0
C(0) = 140t - (0.3/2) t²
Profit P(t) = R(T) - C(T) , hence the total profit from t = 0 to t = 5 is given as:
P(t) = ![\int\limits^0_5 {[R'(t)-C'(t)]} \, dt =\int\limits^0_5 {([100e^t-(140-0.3t)]} \, dt=\int\limits^0_5 {100e^t} \, dt +\int\limits^0_5 {-0.3t} \, dt +\int\limits^0_5 {-140} \, dt \\\\=[100e^t]_0^5+[ -140t]_0^5+[-0.3t^2/2]_0^5=[14841.316-100]+[-700]+[-3.75]=14038](https://tex.z-dn.net/?f=%5Cint%5Climits%5E0_5%20%7B%5BR%27%28t%29-C%27%28t%29%5D%7D%20%5C%2C%20dt%20%3D%5Cint%5Climits%5E0_5%20%7B%28%5B100e%5Et-%28140-0.3t%29%5D%7D%20%5C%2C%20dt%3D%5Cint%5Climits%5E0_5%20%7B100e%5Et%7D%20%5C%2C%20dt%20%20%2B%5Cint%5Climits%5E0_5%20%7B-0.3t%7D%20%5C%2C%20dt%20%20%2B%5Cint%5Climits%5E0_5%20%7B-140%7D%20%5C%2C%20dt%20%20%5C%5C%5C%5C%3D%5B100e%5Et%5D_0%5E5%2B%5B%20-140t%5D_0%5E5%2B%5B-0.3t%5E2%2F2%5D_0%5E5%3D%5B14841.316-100%5D%2B%5B-700%5D%2B%5B-3.75%5D%3D14038)
The profit is $14038
The correct option is B. In this type of economy the government has total control over allocation of all resources. <span />
