Answer:

The opposite wave of same frequency...

Explanation:

Let us take an example. We know the noise cancellation property of most of the modern headphones. When sounds from the environment is picked up by the microphone embed into the headphones, a opposite wave of same frequency is transmitted out that interact destructively and causes destructive interference and cancel out each other in this process.

Fittoniya [83]

Answer:

Q=7.9\times 10^{-10}\ C

Explanation:

Given that

V= 12 V

K=3

d= 2 mm

Area=5.00 $ 10#3 m2

Assume that

$ = Multiple sign

# = Negative sign

A=5\times 10^{-3}\ m^2

We Capacitance given as

For air

C_1=\dfrac{\varepsilon _oA}{d}

C_1=\dfrac{\varepsilon _oA}{d}

C_1=\dfrac{8.85\times 10^{-12}\times 5\times 10^{-3}}{2\times 10^{-3}}

C_1=2.2\times 10^{-11}\ F

C_2=\dfrac{K\varepsilon _oA}{d}

C_2=\dfrac{3\times 8.85\times 10^{-12}\times 5\times 10^{-3}}{2\times 10^{-3}}\ F

C_2=6.6\times 10^{-11}\ F

Net capacitance

C=C₁+C₂

C=8.8\times 10^{-11}\ F

We know that charge Q given as

Q= C V

Q=12\times 6.6\times 10^{-11}\ C

Q=7.9\times 10^{-10}\ C

A 615 N student standing on a scale in an elevator notices that the scale reads 645 N. From this information, the student knows
BARSIC [14]

Answer:

The elevator must be moving upward.

Explanation:

During the motion of an elevator, the weight of the person deviates from his or her actual weight. This temporary weight during the motion is referred to as "Apparent Weight". So, when the elevator is moving downward, the apparent weight of the person becomes less than his or her actual weight.

On the other hand, for the upward motion of the elevator, the apparent weight of the person becomes more than the actual weight of that person.

Since the apparent weight (645 N) of the student, in this case, is greater than the actual weight (615 N) of the student.

<u>Therefore, the elevator must be moving upward.</u>

What is an ion found in a glass of water
stepladder [879]

Answer:

H^{+} ion and OH^{-} ions.

Explanation:

As we notice the glass of water, in this observation we find that the glass also made up of sodium silicate which will give us oxygen ion.

And the water which is present in the glass will break into the hydroxyl ion and H^{+} ion .

Therefore, glass of water contains H^{+} ion and OH^{-} ions.
