CONNECTIONS BETWEEN PLACES<br> 14. What is diffusion?

A turntable with mass m, radius R, and rotational

Gennadij [26K]

The clay-turntable system's rotational inertia after strike will be (2/3)mR². Then the correct option is C.

<h3>What is rotational inertia?</h3>

The summation of the product of the mass of each particle with its square of the distance from the rotational axis is the moment of inertia, which is the amount denoted by the body resistant angular acceleration.

A turntable with mass m, radius R, and rotational inertia (mR²)/2 initially rotates freely about an axis through its center at constant angular speed with negligible friction.

A piece of clay, also of mass m, falls vertically onto the turntable and sticks to it at point P, a distance R/2 from the center of rotation.

Then the clay-turntable system's rotational inertia after strike will be

$\rm I = I_0 + m *\dfrac{ R^2}{2}\\\\I = m* \dfrac{R^2}{2^2} + m * \dfrac{R^2}{2}\\\\I = \dfrac{3}{4}mR^2$

More about the rotational inertia link is given below.

March 1st Beginning inventory 6 $500 $3,000 $3,000

March 7th Purchases 6 $500 $3,000 $6,000 ($3,000 + $3,000)

Week 1 Cost of Sales -1 $500 $500 $5,500 ($6,000 - $500)

March 14th Purchases 6 $510 $3,060 $8,560 ($5,500 + $3,060)

Week 2 Cost of Sales -8 $504 $4,032 $4,528 ($8,560 - $4,032)

March 21st Purchases 6 $510 $3,060 $7,588 ($4,528 + $3,060)

March 28th Purchases 6 $505 $3,030 $7,582 ($4,552 + $3,030)

Week 4 Cost of Sales -5 $505 $2,525 $5,057 ($7,82 - $2,525)

Sales revenue = 20 x $800 = $16,000

Cost of goods sold = Cost of goods available – Ending inventory

= $10,093 ($15,150 - $5,057)

Gross margin for March = $5,907 ($16,000 - $10,093)

March 28th Purchases 6 $505 $3,030 $7,620 ($4,590 + $3,030)

Week Four Cost Sales -5 $510 $2,550 $5,070 ($7,620 - $2,550)

Sales revenue = 20 x $800 = $16,000

Cost of goods sold = Cost of goods available – Ending inventory

= $10,080 ($15,150 - $5,070)

Gross margin for March = $5,920 ($16,000 - $10,080)

Thus, Velentina's gross margin or profit is the difference between its sales revenue and the cost of goods sold.
