Answer:
Explanation:
As we know that resistance of one copper wire is given as
here we know that
now we have
now we know that such 17 resistors are connected in parallel so we have
Now if a single copper wire has same resistance then its diameter is D and it is given as
now from above two equations we have
now we have
I think the correct answer would be that the temperature of the clouds that made the very first stars where thought to be higher since the clouds are made up of hydrogen and helium. Hope this answers the question. Have a nice day.
Answer:
Correct answer is option D
- Wire is on the cylinder axis and carries current i in the direction opposite to that of the current in the shell
Explanation:
- It cannot be Option E, because the magnetic field outside the wire would not be 0 due to the current carried by the conductor
-Also, the parallel wire cannot carry current in the same direction because, that would amplify the magnetic field created by the outer cylinder (since B is dir. proportional to the current) -and now, that leaves only option C and D. If, it is Option C, then that means one side of the cylinder would be more closer to the parallel wire than the other, so there would be different B fields on the two opposite sides of the cylinder. So, that means the answer is option D.
Answer:
1. The resistance of any physical object to any velocity
2. It continues in it's existing state of rest or uniform motion
3. Mass is a quantity that is solely dependent upon the inertia of an object.
