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 × 10^{6}

Time = 8 h = 8 × 60 × 60

 = 28800 seconds

Average useful power = \frac{6 ×10^{6} }{28800}

                                     = 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

                  = \frac{29400}{208.33} \\

                  = 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.

AveGali [126]

Answer:

N. Corporation

The effect on earnings in the year after the options are granted to executives is a reduction in the net income by $16 million because of the Compensation Expense that will be recorded.

The journal entry on December 31, 2021 (a year after) is:

Debit Compensation Expense $16,000,000

Credit Stock Options $16,000,000

To record compensation expense.

Explanation:

a) Data and Calculations:

Options grant date = January 1, 2021

Options granted = 12.0 million shares

Options vesting date = December 31, 2023

There are 3 years before the vesting date

Fair value of the options = $4

Therefore, Total Compensation Expense = Options granted*Fair value per option

= 12,000,000 * $4

= $48,000,000

Annual compensation expense from 2021 to 2023 = $48,000,000/3

= $16,000,000

Creme Bakery just paid an annual dividend of $2.20 a share and is expected to increase that amount by 2.2 percent per year. If y
alekssr [168]

Answer:

$19.47

Explanation:

The computation of the price paid for share is shown below:

= Year second dividend ÷ (Required rate of return - growth rate)

where,

Next year dividend is

= $2.20 + $2.20 × 2.2%

= $2.20 + $0.0484

= $2.2484

In the year 2 , it is

= $2.2484 × 1.022

= $2.2978648

And, the required rate of return is 14%

Plus the growth rate is 2.2%

So, the price paid for the share is

= ( $2.2978648) ÷ (14% - 2.2%)

= $19.47
