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.

A displacement vector is 34.0 m in length and is directed 60.0° east of north. What are the components of this vector? Northward
PolarNik [594]

Answer:

A)  29.4 m 17.0 m; B) 2 m

Explanation:

If a vector is 34.0 m in length and is directed 60.0° east of north (which means 30.0° over the horizontal), then its coordinates will be:

Horizontal: (34.0 m)cos(30.0°)=29.4 m

Vertical: (34.0 m)sin(30.0°)=17 m

If one person walks 8.0 meters in a straight line and then walks 5.0 meters in another straight line, then the minimum displacement would be to go back over his tracks, displacing himself 8m-5m=3m, while the maximum displacement would be going straight ahead, displacing himself 8m+5m=13m. Any answer outside this interval is impossible (2m).

1.How is the law of conservation of energy demonstrated by the movement of the pendulum?
Snezhnost [94]
1. Law of conservation of energy states that energy cannot be created, nor destroyed, for example, windmills take kinetic energy(movement energy) and convert it into electrical energy using gears and a generator as well as the blades.

so this supports it because the pendulum never reaches the same height twice unless you reset it so the energy is always getting less and less and not randomly getting back onto the pendulum.

2.Gravity, friction and air resistance slow it down as well

3. at the top, potential energy is the amount of energy something has relative to the amount it can disperse before stopping, for example, a book on a shelf has more potential energy than that of a book on a table, this is because when the shelf book falls it will create more energy than the table book.

newton's second law states that when a net force acts on an object, it accelerates it.Explain how it would be possible for two o
Alika [10]

Answer:

See Explanation

Explanation:

According to Newton's second law of motion, the acceleration of a body is proportional to the net external force that acts on the body.

A body accelerated when it is acted upon by an unbalanced net external force.

When the external forces acting on a body are balanced, the effect of each force is cancelled by the other hence the body is not accelerated according to Newton's second law.
