Answer:
Explanation:
In electric circuit , the potential difference is always developed across the resistance .
Now is we are to amplify the voltage , that means low input voltage is converted into high voltage output .
Therefore we require low resistance at input for low voltage and high out put resistance for high output
Thus the statement given is wrong .
<h2>
So, the correct answers are:</h2>
Travels in longitudinal waves
Travels most slowly through a gas
Speeds up when temperature is increased
Is caused by vibration
Explanation for correct answers:
Yes, it does travel in longitudinal waves
Yes, sounds weird, but travels faster in the water
Yes, does speed up when temperature is increased
And yes, Is caused by vibration.
<h2>
Wrong answer is:</h2>
Can travel through a vacuum
Explanation for wrong answer:
actually, in space, there is NO sound, because there are no particals for the sound to vibrate with, there's just empty SPACE.
Answer: The magnetic flux is 3.4 × 10^-3 Wb
Explanation: Please see the attachments below
Answer:
a) 
b) 
Explanation:
Get the reactive powers for each of the loads:
Reactive power = Real Power * tanθ
For load 1
Active power, P₁ = 100 W
Power factor, 


For load 2
Active power, P₂ = 250 W
Power factor, 


For load 3
Active power, P₃ = 250 W
Power factor, 


Calculate the total reactive power, 

Calculate the total active power, 



V = 115 

b) Power factor of the composite load is 

It can be concluded that John lives at the Arctic Circle.

</h3><h3>Why sun don't sets at arctic circle?</h3>
The North Pole is inclined toward our star throughout the summer because of the slanted axis of the earth's rotation with respect to the sun. Because of this, the sun never sets over the Arctic Circle for a few weeks.
Norway. Norway, which is located in the Arctic Circle, is known as the Land of the Midnight Sun because there the sun never sets from May until late July. This implies that the sun doesn't set for around 76 days.
