Reika [66]

Answer:

B

Explanation:

Under process​ costing, costs assigned to goods sold are transferred to the Cost of Goods Sold account from the​  Finished goods inventory account

The simple reason can be that Earlier than they are transferred to cost of goods sold account and being sold, they are finished goods right before it. So, they are actually transferred from finished goods inventory account only.

Misha Larkins [42]

Answer:

                                E =17,280 J

Explanation:

Since the voltage drops linearly from 6V to 4V, the average is 5V. The energy delivered is .

V is the average of initial and fianl voltage

A is the current passing

t is the time in which current is passed

               E=V*A*t = 5*0.015*(64*3600) = 17,280 J

Consider the possibility of using two rotating cylinders to replace the conventional wings on an airplane for lift. Consider an
EleoNora [17]

Answer:

27.35m

Explanation:

For the calculation of the Support Force we rely on the formula for obtaining the force in a cylinder of a certain length l,

F_y = - \rho Ul\Gamma

Here each term is,

F_y= Lift force

\rho= density of air

\Gamma = vortex strength

For this last equation, its mathematical representation is given by,

\Gamma = 2\pi av_{\theta}

Here each term is,

a= 1m, radios of cylinder

v_{\theta}= 20 Km/hr=5.5m/s, the velocity of cylinder surface.

\Gamma = 2\pi (1)(5.5) = 34.90m^2/s

In order to find the density of the area at 2000m we will refer to the table of Standard Atmosphere of the United States, that is 1.007kg/m^3,

U= 150Km/hr = 41.6m/s, F_y = 40000N, \Gamma = 34.90m^2/s

Replacing the values,

40000 = -(1.007)(41.6)l(34.90)

Clearing l and solving for it we have,

l=-27.35m

<em>In this way we can conclude that the length of the cylinder must be 27.35m</em>
