Answer:
Kinetic energy increases because iron shavings move in the direction of magnetic force.
Potential energy decreases, and kinetic and thermal energy increase.
Potential energy increases because movement is in the opposite direction of the magnetic field.
They seek a rail line not affected by friction.
We need it to calculate the how big it is, it’s mass, or even volume to get the measurements of lots of objects
Answer:
I = 0.96 A
Explanation:
No of electrons, 
Time, t = 3 ms = 
We need to find the electric current. We know that electric charge per unit time is equal to the electric current.
q = ne (Quantization of electric charge)
So, the electric current is 0.96 A.
A material you are testing conducts electricity but cannot be pulled into wires. It is most likely a metalloid. Hope this helps!
