Answer: There is no fiscal policy action that can keep the inflation and unemployment stable.
Explanation:
If there is a negative real shock such as an oil crisis, it will be hard fir the affected economy to adjust and be stable.
A negative real shock will lead to a reduction in growth and a rise in inflation. Even in cases whereby there is an increase in the money supply, this will lead to a rise in real growth but the result will be that there will be an higher inflation
Therefore, there is no fiscal policy action that can keep the inflation and unemployment stable.
Answer:
When we get too hot, sweat glands in the skin release more sweat. The sweat evaporates, transferring heat energy from the skin to the environment.
Solution:
Given Information,
Heat input is (
) = 5.5 ×
Btu/h
Combustion efficiency of the boiler (
) = 0.7
Combustion efficiency after turn up (
) = 0.8
Operation Hour (t) = 5200h
Unit cost (c) = 
Calculate heat output from the boiler
=
x 
= 5.5 x
x 0.7
= 3.85 x
Btu/h
Calculate the heat input to the boiler after the tune-up
=
/ 
= 3.85 x
/ 0.8
= 4.8125 x
Btu/h
Calculate the saved energy after the tune-up
=
- 
= 5.5 x
- 4.8125 x
Btu/h
= 0.6875 x
Btu/h
Calculate the annual energy saving (
)
=
x t
= ( 0.6875 x
Btu/h ) ( 5200 hr/yr)
= 3575 x
Btu/h
Calculate the annual cost saving
Annual cost saving =
x Unit cost
= 3575 x
Btu/h x 
= 82225
Answer:
Persists because economic wants exceed available productive resources.
Explanation:
According to Lionel Robbins, Economics is the science which studies human behavior as a relationship between ends and scarce means which have alternative uses.
The problem of scarcity is that our wants are always beyond what we can produce with our resources.
Economics is the solution to this problem of what resources to use, how best to use them, and when to use them.
Because of this scarcity, all people have to make choices. When making choices, we assess the opportunity cost or the alternative forgone.
The opportunity cost of taking action is what we could have got if we had taken an alternative action.
