Materials that have low resistance to electric current are called electric conductors. Many metals - including copper, aluminum, and steel are good conductors of electricity. The outer electrons of metal atoms are loosely bound and free to move, allowing electric current to flow
Answer:
Explanation:
Given that,
Vector 
............(1)
We need to find the magnitude of vector A. Let us suppose vector in the form of, R = xi + yj + zk. Its magnitude is given by :
In equation (1),
x = 1
y = -2
z = 3
So, the magnitude of vector A is given by :
|A| = 3.74
So, the magnitude of given vector is 3.74. Hence, this is the required solution.
