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.

omeli [17]

Answer:

The mechanical energy is converted to potential energy while the kinetic energy is zero

Explanation:

mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object. The total mechanical energy is the sum of these two forms of energy.

The Law of Conservation of Energy: Energy cannot be created or destroyed, but is merely changed from one form into another. This means that potential energy can become kinetic energy, or vice versa, but energy cannot “disappear”.

The mechanical energy is converted to potential energy while the kinetic energy is zero

A swan on a lake gets airborne by flapping its wings and running on top of the water. If the swan must reach a velocity of 6.00
ira [324]

Answer:

A. 51.42 m.

B. 17.14 s.

Explanation:

Using equations of motion:

vf^2 = vi^2 + 2 * aS

Where,

vf = final velocity

a = acceleration

S = distance to which swan traveled

vi = 0 m/s

6.00^2 = 2 * 0.350S

S = 36/0.7

= 51.42 m.

B.

vf = vi + at

6 = 0 + 0.35t

t = 6/0.35

= 17.14 s.

A water rocket can reach a speed of 75 m/s in 0.050 seconds from launch. What is its average acceleration?
yanalaym [24]
A=v/t
So therefore 75/0.050= acceleration
So the answer is a= 1500 metres per second per second

Which of the following statements about the nature of electrical charge is FALSE? Positive-positive or negative-negative charges
Ilya [14]

Answer:

All of the above statements are true.

Explanation:

All matter is composed of atoms of which have subatomic particles. Subatomic particles are electrons, protons and neutrons. Each particle has electric charges.

Electrons have a negative charge, protons have a positive charge and neutrons have zero charge.

Between two nearby charges initially at rest, a type of forces, called electrostatic, is always established in such a way that, if the charged particles are small enough so that they can be considered punctual, the following conditions are met:

  • The force established between the two has a direction that coincides with an imaginary straight line that joins the two charges.
  • The force exerted on one load points towards the other when the two have different signs, one positive and the other negative. (attractive force).
  • The sense of force is directed to the opposite side of the charge when both have the same sign (repulsive force).
