Answer:

A puck hovers and glides across an air track at constant velocity is the scenario where a non-conservative force acts(air friction)

Explanation:

Conservative forces are the forces which are path-independent.

so, total work done by conservative forces in a closed loop is zero

Now, non-conservative forces are path-dependent forces.

These are dissipative forces in nature, so total work done by non-conservative forces is not zero.

Option a) A puck hovers and glides across an air track at constant velocity.

Even though puck moves with constant velocity there will air drag force which is friction and non-conservative in nature. so, to keep puck to move with constant velocity we need to compensate this friction.

Option b) A dishwasher was pulled up to a window by a rope using a pulley system.

Here, work is done against gravitational force which is conservative in nature.

Option c) A feather falls from one end of a tube to the other inside a vacuum.

Here, there are no forces. feather just moves in vacuum, so, the work done is also zero.

Option d) A charged particle was pushed away by another charged particle.

here, these are forces generated by electric charges, which are similar to gravitational force. so, these are also conservative forces.

Trevor Company expects sales of Product W to be 60,000 units in April, 75,000 units in May, and 70,000 units in June. The compan
Sedbober [7]

Answer:

65000 units

Explanation:

Given:

Expected sales of product W in April  = 60000 units

Expected sales of product W in May  = 75000 units

Expected sales of product W in June  = 70000 units

Inventory in hand at the end of each month = 40% of the next month's expected sale

Inventory expected at the end of the April = 40% of the expected sales in May

or

Inventory expected at the end of the April = 0.4 × 75000 = 30000 units

Therefore, the total units required in April =  Expected sales of product W in April + Inventory expected at the end of the April

or

the total units required in April = 60000 + 30000 = 90000 units

Now,

Excessive production in March (inventory) = 25000 units

Hence, the units required to be produced in April = the total units required in April - Excessive production in March (inventory)

or

the units required to be produced in April = 90000 - 25000 = 65000 units

Quench, a bottled water supplier, has 5,496 bottles of water in their warehouse at the end of April. One third of the bottles we
Serjik [45]

Answer:

<u>COGS 6,786.75</u>

<u></u>

Explanation:

<u>First, </u>We calculate the beginning inventory:

5,496 x 1/3 = 1,832 bottles x $1 February =  $  1,832

5,495 x 1/3 = 1,832 bottles x $1.25 March = $  2,748

5,495 x 1/3 = 1,832 bottles x $1.75 April    = $  3,206

<u>Second,</u> We  start subtract the first units from the sales until get zero

<em>sales 4,925 </em>

        <u>-1,832</u> february bottles                 1,832

<em>          3,093</em>

        <u>-1,832</u> march bottles                    2,748

<em>          1,261</em>

        <u>-1,261</u> April bottles x 1.75 =          2,206.75

<em>                0</em>

<u>Third</u>, we add them to get the COGS

COGS 6,786.75
