This diagram shows the process that powers stars. This process is called?
2 answers:
<u>Answer: </u>The correct answer is Option C.
<u>Explanation:</u>
A star is defined as a fixed point in the night sky which illuminates and is very large. the primary element present in stars is Hydrogen and it continuously changes to helium by a process known as Nuclear fusion reaction. This process releases a huge amount of energy.
Nuclear fusion reaction is defined as the combination of lighter nuclei to form a heavy nuclei. In Stars, hydrogen atoms combine to form a helium atom.
The reactions which takes place in stars follows a series of equations:
Overall reaction for the above series of reactions is given by:
Hence, the correct answer is Option C.

Answer:
a . 0.35cm
b. 11.33cm
Explanation:
a. Given both currents are in the same direction, the null point lies in between them. Let x be distance of N from first wire, then distance from 2nd wire is 4-x
#For the magnetic fields to be zero,the fields of both wires should be equal and opposite.They are only opposite in between the wires:
Hence, for currents in same direction, the point is 0.35cm
b. Given both currents flow in opposite directions, the null point lies on the other side.
#For the magnetic fields to be zero,the fields of both wires should be equal and opposite.They are only opposite in outside the wires:
Let x be distance of N from first wire, then distance from 2nd wire is 4+x:
Hence, if currents are in opposite directions the point on x-axis is 11.33cm
