Answer:
The resistance must be 6.67![\Omega](https://tex.z-dn.net/?f=%5COmega)
Solution:
Resistance, ![R_{1} = 20\Omega](https://tex.z-dn.net/?f=R_%7B1%7D%20%3D%2020%5COmega)
Resistance, ![R_{2} = 10\Omega](https://tex.z-dn.net/?f=R_%7B2%7D%20%3D%2010%5COmega)
For the current to be the same when the switch is open or closed, the resistances must be connected in parallel as current is distributed in parallel with the same voltage across the circuit:
Thus in parallel:
![\frac{1}{R_{eq}} = \frac{1}{R_{1}} + \frac{1}{R_{2}}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7BR_%7Beq%7D%7D%20%3D%20%5Cfrac%7B1%7D%7BR_%7B1%7D%7D%20%2B%20%5Cfrac%7B1%7D%7BR_%7B2%7D%7D)
![\frac{1}{R_{eq}} = \frac{1}{20} + \frac{1}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7BR_%7Beq%7D%7D%20%3D%20%5Cfrac%7B1%7D%7B20%7D%20%2B%20%5Cfrac%7B1%7D%7B10%7D)
![R_{eq} = 6.67\ \Omega](https://tex.z-dn.net/?f=R_%7Beq%7D%20%3D%206.67%5C%20%5COmega)
Answer:
OK HERE
Explanation:
When raising a power to a power in an exponential expression, you find the new power by multiplying the two powers together. For example, in the following expression, x to the power of 3 is being raised to the power of 6, and so you would multiply 3 and 6 to find the new power.

The blu-ray standard that defines rewritable disks is BD-RE which stands for Blu-ray Disc Recordable.
<h3>
What is BD-RE?</h3>
BD-RE stands for Blu-ray Disc Recordable and it refers to two direct to disc optical disc recording technologies that can be recorded on to a Blu-ray-based optical disc with an optical disc recorder.
Thus, the blu-ray standard that defines rewritable disks is BD-RE which stands for Blu-ray Disc Recordable.

Answer: <u><em>C. Steel</em></u>
Explanation: <em><u>When a sound wave travels through a solid body consisting</u></em>
<em><u /></em>
<em><u>of an elastic material, the velocity of the wave is relatively</u></em>
<em><u /></em>
<em><u>high. For instance, the velocity of a sound wave traveling</u></em>
<em><u /></em>
<em><u>through steel (which is almost perfectly elastic) is about</u></em>
<em><u /></em>
<em><u>5,060 meters per second. On the other hand, the velocity</u></em>
<em><u /></em>
<em><u>of a sound wave traveling through an inelastic solid is</u></em>
<em><u /></em>
<em><u>relatively low. So, for example, the velocity of a sound wave</u></em>
<em><u /></em>
<em><u>traveling through lead (which is inelastic) is approximately</u></em>
<em><u /></em>
<em><u>1,402 meters per second.</u></em>
