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.
Frequency, υ = 2.09 Hz
We know that time period, T = 1/υ
∴ T = 1 ÷ 2.09
⇒ T = 0.4784 seconds
We will first record its mass and then its volume by measuring its dimensions
then divide mass by volume and will get density of regular solid
Bc the gravitational pull on saturn is more than that of the earth
Answer:
-200°C
Explanation:
This is because at -200°C the temperature is below -196°C and above -210°C .Thus Nitrogen can be in liquid state.
