Answer:
The value is
Explanation:
From the question we are told that
The radius of the conductor is
The current it is carrying is
The electric field is
Generally the resistivity of the material is mathematically represented as
Here A is the area of the conductor which is mathematically represented as
=>
=>
So
=>
I believe it's A. Sorry if I'm incorrect.
This is caused my a magic illusion and when you stand at a certain angle in themirror it changes your image
Answer:
the object will move
Explanation:
well if you push an object it will move.
To calculate the length of the wire, we use formulas,
(A)
(B)
Here, R is the resistance of the wire, I is the current flows through wire and V is potential difference. A is cross sectional area of wire and is the density of copper wire and is value,.
Given
Substituting the values of I and V in equation (A ) we get,
Now from equation (B),
Therefore,
Thus the length of the copper wire is 177.9 m.
