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.
Answer:
Building C
Explanation:
Building A: Purchase for a cash price of $620,000, useful life 27 years.
Building B: Lease for 27 years with annual lease payments of $71,170 being made at the beginning of the year.
Building C: Purchase for $657,500 cash. This building is larger than needed; however, the excess space can be sublet for 27 years at a net annual rental of $6,200. Rental payments will be received at the end of each year.
11% cost of funds
we must determine the present value of each option:
- Building A's present value = $620,000
- Building B's present value = $71,170 x 9.48806 (PV annuity due factor, 11%, 27 periods) = $375,265.23
- Building C's present value = $657,500 - [$6,200 x 8.5478 (PV ordinary annuity factor, 11%, 27 periods) = $657,500 - $52,996.36 = <u>$604,503.64 (LOWEST PV)</u>
Answer:
$8,250
Explanation:
Relevant data provided for compute the Uncollectible Accounts Expense is here below:-
Amount written off = $6,300
Closing balance = $5,400
Opening balance = $3,450
The computation of Uncollectible Accounts Expense is shown below:-
Uncollectible Accounts Expense = Amount written off + Closing balance - Opening balance
= $6,300 + $5,400 - $3,450
= $11,700 - $3,450
= $8,250
Therefore for computing the Uncollectible Accounts Expense we simply applied the above formula.
