The magnetic field is responsible for levitating the hoverboard and rider as it traverses the half pipe.

<h3>What is a magnetic field?</h3>
  • The magnetic field is defined as the field the magnetic materials generate or when an electric charge moves in a field region that generates the magnetic field.
  • The surface is made up of from the copper and copper is conductor of electricity.
  • When an electrical charge moves, it generates a magnetic field. As with electrical current running via a wire, the spinning and orbiting of an atom's nucleus produces a magnetic field.
  • Thus, the magnetic field is responsible for levitating the hoverboard and rider as it traverses the half pipe.
<h3>What is the characteristics of Magnetic fields?</h3>
  • Magnetic field lines never cross one another.
  • They begin (from the north pole) and end (to the south pole) perpendicular to the surface of the magnet. Magnetic field lines also run through the magnet.
  • The magnetic field is denser at the poles and less dense as we move away from them.
  • A single magnetic pole does not exist. Magnetic poles are always found in pairs of opposing poles.

A jet airliner moving initially at 406 mph (with respect to the ground) to the east moves into a region where the wind is blowin
astraxan [27]

Answer:

966 mph

Explanation:

Using as convention:

- East --> positive x-direction

- North --> Positive y-direction

The x- and y- components of the initial velocity of the jet can be written as

v_{1x} = 406 mph\\v_{1y} = 0

While the components of the velocity of the wind are

v_{2x} = (568)(cos 15^{\circ})=548.6 mph\\v_{2y} = (568)(sin 15^{\circ})=147.0 mph

So the components of the resultant velocity of the jet are

v_x = v_{1x}+v_{2x}=406+548.6=954.6 mph\\v_y = v_{1y}+v_{2y}=0+147.0=147.0 mph

And the new speed is the magnitude of the resultant velocity:

v=\sqrt{v_x^2+v_y^2}=\sqrt{(954.6)^2+(147.0)^2}=965.8 mph \sim 966 mph
