A) You have just moved into a new apartment and are trying to arrange your bedroom. You would like to move your dresser of weight 3,500 N across the carpet to a spot 5 m away on the opposite wall. Hoping to just slide your dresser easily across the floor, you do not empty your clothes out of the drawers before trying to move it. You push with all your might but cannot move the dresser before becoming completely exhausted. How much work do you do on the dresser?

W> 1.75 x 10^4 J
W = 1.75 x 10^4 J
1.75 x 10^4 J > W > 0 J
W = 0 J

B) A box of mass m is sliding down a frictionless plane that is inclined at an angle ϕ above the horizontal, as shown in the figure (Figure 2) . What is the work done on the box by the force due to gravity w, if the box moves a distance d?

A. W = 0joule

B.W = d * w * cos (90 -ø)

Explanation:

work done is force multiplied by distance since the distance covered by the dresser is zero so automatically work done in moving the dresser is 0 (zero)

B. The component of weight of box along the inclined plane = w * cos ( 90 - ø )

Where ø is the angle of inclination to the horizontal

W = weight of body due to gravity.

Since the distance traveled by box due to gravity = d

So therefore:

W = d * w * cos (90 -ø)

W = work done

both are integral parts of a corporate balance sheet. the cash flow statement, or statement of cash flows, measures the sources of a company's cash and its uses of cash over a specific time period. the income statement measures a company's financial performance, such as revenues, expenses, profits or losses over a specific time period (in fact, it's sometimes called a statement of financial performance).

a cash flow statement shows exactly how much money a company has received and how much it has spent, traditionally over a period of one month. it captures the current operating results and changes on the balance sheet, such as increases or decreases in accounts receivable or accounts payable, and does not include noncash accounting items such as depreciation and amortization. the cash flow generally comes from revenue received as a result of business activity, but it may be augmented by funds available as a result of credit. a cash flow statement is used to determine the short-term viability and liquidity of a company, specifically how well it is positioned to pay its bills and vendors.

the correct answer is b.)
