hello your question is incomplete attached below is missing part of the question
answer:
1 ) Magnetic field due to long current carrying wire : 
Therefore the net magnetic field due the both wires ; B = B
+ B
. when we adjust the current I = I then the Netfield (B ) = zero
2) The distance between the field lines are not equally spaced and this is because the separation between field lines increases with the increase in the distance between the wires
3) Increase in current through the wire will lead to increase in force and this can be explained via this equation

Nitrogen could form 3 bonds based on octet rule, because it has 5 valence electrons. That means it needs 3 bonds.
Explanation:
- A nitrogen atom can fill its octet by sharing three electrons with another nitrogen atom, forming three covalent bonds, a so-called triple bond.
- A triple bond isn't quite three times as strong as a single bond, but it's a very strong bond.
- Every covalent bond is a sharing of two electrons between two atoms. A double bond is 4 electrons being shared (2x2). Therefore a triple bond is 6 electrons being shared (2x3)
- Triple bonds are stronger than double bonds due to the the presence of two pi bonds rather than one.
- Each carbon has two sp hybrid orbitals, and one of them overlaps with its corresponding one from the other carbon atom to form an sp-sp sigma bond.
- A single lone pair can be found with atoms in the nitrogen such as nitrogen in ammonia , two lone pairs can be found with atoms in the chalogen group such as oxygen in water and the halogen can carry three lone pairs such as in hydrogen chloride. Nitrogen has 2 lone pairs.
Answer: from vector law opposite we minus
Hence
425n-300n=125n to the right
Hints in left vector have -Ve sign while right have +Ve sign
Explanation:
if <em><u>the temperature changes , the liquid in the thermometer expands by a certain fixed amount, independent on the shape and the diameter of the capillary, only dependent on the amount of liquid. You can imagine but we'll see height difference upon a temperature changes if diameter is not </u></em><em><u>constant</u></em>
