Answer:
Resistance of the second wire is twice the first wire.
Explanation:
Let us first see the formula of resistance;
R = pxL/A
Here L is the lenght of the wire, A the area and p is the resistivity of wire.
As we are given that the length of second wire is double than that of the first wire, hence the resistance of second wire would be double.
Since we have two loop in second case, inducing double voltage but as resistance is doubled so the current would remain same according to ohms law
I = V/R
Answer:
For whom are goods and services to be produced? In other words, who gets what?
What should we produce?
For whom should we produce it?
Explanation:
Diffraction means spreading out of waves that has the same wavelength as the size of the gap. Sound waves have high wavelength and so it diffracts\spreads out and enables anyone to hear your voice from anywhere outside the room.
For inside the room, the sound waves doesn't actually diffract. They collide with the air particles, causing a series of compressions and rarefactions which spreads out in the air particles and anyone can hear your voice.
Air is the medium for the sound waves to travel.
The precision of the measuring instruments will be 2.5%.
<h3>What is precision?</h3>
It should be noted that precision simply means how close a test result will be when it's repeated.
In this case, the precision of the measuring instruments will be:
= (2 - 1.95)/2.
= 0.05/2
= 2.5%
Therefore, the the precision of the measuring instruments will be 2.5%.
