Answer:
No, it is not magnetized.
Explanation:
Bar B does not necessarily have to be magnetized before it can be attracted to a magnet. It just has to be a magnetic material such as Iron.
If bar B were magnetized, it could either be attracted or repelled by the magnet since this would depend on the side of the pole of bar B facing it.
Since we are not given any information about bar B other than it is attracted to the magnet, it is thus not magnetized.

➪x= √ 85
Explanation:
x²+√4 = 87
=> x²+2 = 87
=> x² = 87-2
=> x²= 85
=> x= √85
That statement is true.
the capacitor is initially uncharged, but starts to charged when the switch is closed.
The potential difference across the resistor will steadily dropped as the potential difference across the capacitor increased.
<span>According to the Newton's second law of motion F=ma, where F=force
m= Mass
a= acceleration
So F= 0.15*12
=1.8 N </span>
