Which statement best describes the magnetic properties of a material?

Physics
1 answer:
Zigmanuir [339]3 years ago
5 0

Answer:

Magnetic materials have many spinning, unpaired electrons.

Explanation:

Any moving electric charge creates a magnetic field, also electrons since they spin and move around the nucleus. However, if two electrons are paired on the same orbital they always spin in opposite directions that causes their magnetic field to cancel out. Even if there are unpaired electrons in some atoms and these atoms act as small magnets, the magnetic field of the neighbouring atoms can have different directions and they also cancel out each other. Only presence of a large number of unpaired electrons in a material can create a significant magnetic field. This is the root part of the definition of magnetic properties of material.

How do you find the force of a ping-pong ball rolling down a track?
Kaylis [27]

Answer:

Weight

a) weight's vertical component = Normal upward force

b) weight's horizontal component = Friction force = (mass of ball)(acceleration)

These forces depend upon the track,

1) inclined or horizontal

2) steepness.

Explanation

The force of gravity points straight down, but a ball rolling down a ramp doesn't go straight down, it follows the ramp. Therefore, only the component of the weight which points along the direction of the ball's motion can accelerate the ball.

weight's horizontal component = Friction force = (mass of ball)(acceleration)

The other component pushes the ball into the ramp, and the ramp pushes back.

If the ramp is horizontal, then the ball does not accelerate, as gravity pushes the ball into the ramp and not along the surface of the ramp. Hope this helps. Can u give me brainliest
