How does the yarn in the sweater differ from the wool on the sheep

The yarn might be soft and dyed because it has been treated. The wool might be scratchy, itchy (sorry if those are the same), white*, brown*, or gray*, and possibly warmer because it is thicker.

Answer:

Explanation:

Yarn is different from wool on the sheep as wool is a raw material and yarn in the sweater is the product made out pf this.

Wool is directly woven from the animal skin from where it is treated with different procedures to make yarn out of it.

Yarn is used to make textiles, knitting and weaving.

In an oscillating series RLCcircuit, with a 6.13 Ω resistor and a 15.2 H inductor, find the time required for the maximum energy

ivanzaharov [21]

Answer:

time for maximum energy is 1.718 sec

Explanation:

Maximum energy on the capacitor is given as $=\frac{q_{max}^2}{ 2C}$

Maximum energy $= \frac{(1/6) Q_2}{2C}$

The maximum charge is given by

$q_{max} =Qe^{-Rt/2L}$

Or $\frac{q_{max}}{Q} = e^{-Rt/2L}$

Or $ln\frac{q_{max}}{Q} = \frac{-Rt}{2L}$

solving for t

$t = \frac{2L}{R}\frac{1}{2} ln( 2)$

Putting all value to get desired value

$t = ln(2)\times \frac{L}{R}$

$t = 0.693\times \frac{(15.2}{6.13} = 1.71 sec$

Falling objects drop with an average acceleration of 9.8 m/sec/sec, or 9.8 m /s2. If an object falls from the top of a tall buil

Lena [83]

Use the velocity expression for uniform acceleration and solve for t: v = v0 + at. v0 is zero since the object is at rest. 49 m/s = a(t), and solve for t. t = 49 m/s / 9.8 = 5 seconds.

A mover slides a refrigerator weighing 650 N at a constant velocity across the floor a distance of 8.1 m. The force of friction

boyakko [2]

Given :

A mover slides a refrigerator weighing 650 N at a constant velocity across the floor a distance of 8.1 m.

The force of friction between the refrigerator and the floor is 230 N.

To Find :

How much work has been performed by the mover on the refrigerator.

Solution :

Since, refrigerator is moving with constant velocity.

So, force applied by the mover is also 230 N ( equal to force of friction ).

Now, work done in order to move the refrigerator is :

$W = Force\times distance\\\\W = 230 \times 8.1\ N\ m\\\\W = 1863\ N\ m$

Hence, this is the required solution.
