The fluctuation of growth and decline in an economy is called BUSINESS CYCLE OR ECONOMY CYCLE.
The fluctuations in business cycle usually involves shift between period of relatively rapid economic growth and period of relative stagnation or decline. Business cycle is measured by considering the growth rate of real gross domestic product of the nation concerned.
This doesn't seem to be a question, but rather, a statement.
Answer:
0.1125 or 11.25% for each firm
Explanation:
Given that,
Each has $10 million in invested capital,
$1.5 million of EBIT
25% federal-plus-state tax bracket
ROIC for LL:
= [EBIT × (1 - tax rate)] ÷ invested capital
= [1.5 × (1 - 25%)] ÷ 10
= 0.1125 or 11.25%
ROIC for HL
= [EBIT × (1 - tax rate)] ÷ invested capital
= [1.5 × (1 - 25%)] ÷ 10
= 0.1125 or 11.25%
Therefore, the return on invested capital (ROIC) for each firm is 11.25%
Answer:
(a) 208.33 J/s
(b) 141.12 s
Explanation:
(a) Energy is the rate of doing work.
Work is the product of power and time
Work = Power × Time
Power = Work/time
where work is in joule and time is in seconds
Given that work = 6 × 
Time = 8 h = 8 × 60 × 60
= 28800 seconds
Average useful power = 
= 208.33 J/s
(b) Given
mass = 2000kg , using g = 9.8 m/s2
Force = 2000 × 9.8
= 19600N
Work = Force × Distance ( considering that Work done to lift his body can be omitted because it is not considered useful output here)
Work = 19600 × 1.5
= 29,400J
Time taken = Work/Power
= 
= 141.12s
≈ 2 Minutes 21 Seconds
At the rate of 208.33J/s, it will take the person 141.12 seconds to lift 2000 kg of bricks 1.50 m to a platform.
