Answer:
To determine the mystery component we will connect the mystery component to a DC voltage source, then I will measure the resistance of the component with the use of Ohmmeter, the value of the resistance of the mystery component will determine what the mystery component is
if the resistance > 1( very high ) then component is a capacitor
if the resistance = 0 then component is an inductor

Explanation
A) 1.05 N
The power dissipated in the circuit can be written as the product between the pulling force and the speed of the wire:

where
P = 4.20 W is the power
F is the magnitude of the pulling force
v = 4.0 m/s is the speed of the wire
Solving the equation for F, we find

B) 3.03 T
The electromotive force induced in the circuit is:
(1)
where
B is the strength of the magnetic field
v = 4.0 m/s is the speed of the wire
L = 10.0 cm = 0.10 m is the length of the wire
We also know that the power dissipated is
(2)
where
is the resistance of the wire
Subsituting (1) into (2), we get

And solving it for B, we find the strength of the magnetic field:
