one of the properties of the earth's magnetic field is that
the (a) north pole lies in the northern hemisphere [b]
geographic and magnetic meridians coincide (ci earth's
magnetic flux is entirely horizontal at a place where the
magnetic dip is zero (d) earth's magnetic flux is entirely
vertical at a place where the magnetic dip is zero.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

the components of a vector are the parts of the vectors that are to each other.

b perpendicular

you get 2.3=1.21*\frac{a}2 or 4.6=1.21a or a=3.802 (b)
