Answer:
Place the north pole of a magnet next to the north pole of another magnet.
Explanation:
Looking at the comments, we can see that the options are:
Place the south pole of a magnet next to the north pole of another magnet.
Place the north pole of a magnet next to the north pole of another magnet.
First, we know that a positively charged particle will repel another positively charged particle.
The same thing happens for magnetic forces (usually we define a magnetic flow from the south pole to the north pole, so we can define the south pole as the "positive" and the north pole as the "negative", but this is only notation and do not really matter), a south pole of a magnet will repel another south pole of a magnet (and the same happens for the north poles)
Then the correct option is:
Place the north pole of a magnet next to the north pole of another magnet.

Answer:
Explanation:
First of all, we calculate the resistance of the lamp. The power of the lamp is given by
Where
P = 100 W is the power
V = 250 V is the voltage
R' is the resistance of the lamp
Solving for R',
Now this resistance is connected in parallel to the other resistance R, so their equivalent resistance is
(1)
Now the total power in the circuit is
P = 1100 W
And the voltage is
V = 250 V
So we can write
to find the equivalent resistance:
Therefore, rearranging (1), we find R:
