<u>The Weight </u>is a vector whose magnitude is the product of the mass m of the object and the magnitude of the local gravitational acceleration. Its always directed toward the center of the Earth.
Answer:
The current of the outer coil is 
Explanation:
From the question we are told that
The number of turns of the inner coil is 
The radius of the inner coil is 
The current of the inner coil is 
The number of turns of the outer coil is 
The radius of the outer coil is 
Generally the net magnetic field is mathematically represented as
Now from told that the net magnetic field is common
So
Here 
is the permeability of free space
making 
the subject
substituting values
I think it may be c, 1.7 v. I work with electricity a lot.
'A' and 'C' are exactly the same circuit, except the voltmeter's terminals are flipped.
'A' is the correct way to hook everything up.
If you start at the positive terminal of the battery, and follow the flow of current through the circuit and around to the negative terminal, you're following the path where the voltage gets lower and lower and lower all the way.
So each time you come to any device in the circuit ... whether it's a resistor or a meter ... you would be hitting the positive side of it first, and then the voltage where you come out on the other side of it would be lower.
So the left side of the resistor is more positive, and the right side is more negative. The voltmeter is connected correctly in 'A', but it's backwards in 'C'. If you connect the voltmeter like in 'C' and turn things on, the voltmeter will try to go <em>down</em> from zero. You can't read the number on it, and It's possible that the voltmeter might be damaged.
