Answer: Picture (d) is the correct answer.
Explanation:
When liquid nitrogen is at -320 degrees then as the temperature is very low, therefore, molecules of nitrogen will be much closer to each other.
Whereas when liquid nitrogen is boiled then we are increasing the temperature. As a result, force of attraction between the molecules decreases and they will move far apart from each other.
It is known that below 63 K liquid nitrogen tends to freeze and thus it becomes solid. So, at -320 degrees liquid nitrogen will be in solid state.
In the given pictures, picture (d) represents the change caused by adding heat to liquid nitrogen.
The answer is
A magnetic field
Answer:
B) Decrease
Explanation:
Resistance offered due to inductor in any AC circuit is given as
here we know that
= angular frequency
now by ohm's law we know that
here we have
so current is inversely depends on the frequency of AC
so if frequency is increased then the current will decrease
The lists that arranges the Earth's compositional layers in order of increasing density is CRUST, MANTLE AND THEN CORE. The core is considered as the most dense and the lithosphere, which makes the outermost core, is considered as having the least density. Hope that this answer helps.
