A chemical bond results from the mutual attraction of the nuclei for  atoms and electrons.

Explanation:

Each atom tends to have an energy between the nuclei and electrons to keep it stable. So, there will be mutual attraction of the nuclei of atom and of electrons in the innermost shell to the outermost shell. And, this kind of mutual attraction can also be termed as chemical bond or binding energy.

So, depending upon the strength of mutual attraction, the nature of the element can be determined as well as its nature of reactivity can be analysed. So, results as a chemical bond from the mutual attractions of nuclei for atoms and electrons.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
