Answer and Explanation:
There is no probability of obtaining such a circuit of closed track current carrying wire whose field of magnitude displays i.e. 
The magnetic field is a volume of vectors
And 
. This ensures isolated magnetic poles or magnetic charges would not exit
Therefore for a closed path, we never received magnetic field that followed the it is only for the simple current-carrying wire for both finite or infinite length.
The moon has phases because as it orbits earth, which causes the portion we see during each different phase to be shown.
Answer:
Wow that is tough. Go hide lol
Answer:
The new current in the wire is 6.3 A.
Explanation:
Given that,
Force in a straight wire, F = 0.023 N
Current in the wire, I = 2.5 A
If new force is, F' = 0.058 N, we need to find the new current.
We know that, magnetic force is given by :
It is clear that force is directly proportional to electric current. So, we can say:
I' is new current
So, the new current in the wire is 6.3 A. Hence, this is the required solution.
More energy is released in nuclear reactions than in chemical reactions; this is because in nuclear reactions, mass is converted to energy. Nuclear energy released in nuclear fission and fusion is several 100 million times as large as an ordinary chemical reaction like the combustion process. The reason why nuclear energy release so much energy is because tremendous amounts of energy is released at one time. The nuclei in a nuclear reaction undergo a chain reaction, causing the neutrons to move extremely fast and release high amounts of energy.
