Which statement correctly describes magnetic field lines?

Physics

OleMash [197]3 years ago

I believe the correct answer would be they join north pole to south pole. The direction of these lines always goes from the direction of north to south pole. These lines forms loops in order to favor the way which requires or has less resistance. Hope this helps.

Magnetic field lines are presentation of magnetic field on paper

There is no real existence of magnetic field lines in the surrounding of a magnetic material but it is an hypothetical way to represent the magnetic field variation.

There are several rules to draw the field lines on paper which are as following

1. magnetic field lines start from north pole and ends at south pole

2. density of field lines shows the strength of magnetic field

3. tangent to the magnetic field line represents the direction of magnetic field so there can not exist a point where two magnetic field lines will intersect

so as per all above rules the correct answer should be

<em></em>

<em>A. They join north pole to south pole. </em>

Where does all of this energy come from
Amiraneli [1.4K]

Answer: All of our energy comes from the sun, which is our nearest star. The sun sends out huge amounts of energy through its rays every day. We call this energy solar energy or radiant energy. Without the sun, life on earth would not exist, since our planet would be totally frozen.

A person walks 2 miles every day to work, leaving her front porch at 7:00 A.M. and arriving at work at 7:30 A.M. ON the way home
Nataly [62]

Answer:

The displacement is zero miles

Explanation:

The displacement of an object that moves from point A to point B is defined as

d =B-A

Where d is the displacement of the object. The displacement does not depend on the trajectory of the object. It only depends on the linear distance between the end point and the starting point.

In this case we know that the person walks from home to work and then walks from work to home. Therefore, the total displacement is the linear distance between the point where its journey begins and the point where the route ends.

The tour begins on the front porch of your house and ends on the front porch of your house (when you return from work). If we call A to the front porch of the house then the displacement is:

d = A-A = 0

The displacement is zero miles, since the person finishes the journey just where it started (front porch)

Which device is designed to convert chemical energy into kinetic energy ?
irakobra [83]

Answer:

A.C. Generator

Explanation:

The device designed to convert chemical energy into kinetic energy is an A.C generator.

The generator uses fuel to cause the mechanical motion of the pistons in the device.

  • Chemical energy is a form of energy found between the bonds of compounds and molecules.
  • When the bonds are broken, energy is released.
  • The heat energy produced drives pistons and cause mechanical motion of the body.
  • This is a form of kinetic energy which causes the motion of a body.

A piece of wood with density of 824 kg/m^3 is tied to the bottom of a pool and the wood does not move. The volume of the wood is
Reil [10]

Answer:

2069.76 N

Explanation:

density of wood = 824 kg/m^3

density of water = 1000 kg/m^3

Volume of wood = 1.2 m^3

True weight of wood = volume of wood x density of wood x gravity

True weight of wood = 1.2 x 824 x 9.8 = 9690.24 N

Buoyant force acting on wood = volume of wood x density of water x gravity

Buoyant force acting on wood = 1.2 x 1000 x 9.8 = 11760 N

Tension in the rope = Buoyant force - True weight

tension in rope = 11760 - 9690.24 = 2069.76 N
