Sodium, magnesium, and aluminum!
The correct answer among the choices given is the last option. Cora wrapping the copper wire with a thick plastic coating keeps a current from passing out a wire. The plastic wire here serves as an insulator. An insulator is a material that prevents electricity or current to flow out the circuit. In order to lessen the loss of energy.
HOPE THIS HELPS!
A = 1*100 = 100 Ns
b = 10 * 12 = 120 Ns
c = 0.5*1000 = 500 Ns
d = 100 * 2 = 200 Ns
a has least momentum
Explanation:
Assuming that all forces extend from the origin point, with 
and 
lying in the xy plane, so 
is along the z axis. So, we have:
The net force is:
The force (
) that would exactly counterbalance these three forces will be opposite in direction and equal in magnitude to the net force:
