The particles of the medium (slinky in this case) move up and down (choice #2) in a transverse wave scenario.

This is the defining characteristic of transverse waves, like particles on the surface of water while a wave travels on it, or like particles in a slack rope when someone sends a wave through by giving it a jolt.

The other kind of waves is longitudinal, where the particles of the medium move "left-and-right" along the direction of the wave propagation. In the case of the slinky, this would be achieved by giving a tensioned slinky an "inward" jolt. You would see that such a jolt would give rise to a longitudinal wave traveling along the length of the tensioned slinky. Another example of longitudinal waves are sound waves.

Two circular coils are concentric and lie in the same plane. The inner coil contains 110 turns of wire, has a radius of 0.014 m,

Hatshy [7]

Answer:

The current flowing through the outer coils is

Explanation:

From the question we are told that

The number of turn of inner coil is $N _i = 110 \ turns$

The radius of inner coil is $r_i = 0.014 \ m$

The current flowing through the inner coil is $I_i = 9.0 \ A$

The number of turn of outer coil is $N_o = 160 \ turns$

The radius of outer coil is $r_o = 0.022\ m$

For net magnetic field at the common center of the two coils to be zero the current flowing in the outer coil must be opposite to current flowing inner coil

The magnetic field due to inner coils is mathematically represented as

$B_i = \frac{N_i \mu I}{2 r_i}$
