Explain what it means when we say a substance is magnetic

Physics

MariettaO [177]4 years ago
5 0
A magnetic field is a force field, invisibly pushing electrically charged objects just as a gravitational field pulls objects with mass. Whereas all objects with mass exert a gravitational field, however, not all objects have a magnetic field. Magnetic fields are created by electrical charges. Thanks to their structure at the atomic level, some substances -- like the iron in magnets -- have a permanent magnetic field.

Which contribute to both chemical and mechanical weathering? Check all that apply.
larisa86 [58]

organisms and water

Explanation:

Organisms and water contribute to both chemical and mechanical weathering  . A form of weathering known as biological weathering is a derivative of both chemical and physical weathering.

  • Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils.
  • Organisms are pivotal to both physical disintegration of rocks through their activities.
  • Through their metabolic activities, they also releases chemicals that are used for chemical weathering of rocks.

Water is essential for weathering. It is used in alternate freezing and thawing, a mechanical weathering process to break down rocks.

It is used in rock hydrolysis for chemical weathering.

The force diagram represents a girl pulling a sled with a mass of 6.0 kg to the left with a force of 10.0 N at a 30.0 degree ang
Vilka [71]
Normal Force = 54 N
acceleration = 1.2 m/s^2

For Normal Force:
According to the force diagram, we can come up with the equation (all up and down forces):

10 sin 30 + Normal Force - 58.8 = 0
Normal Force = 53.8 N = 54 N

For acceleration:
According to the force diagram, we can come up with the equation (all left and right forces):

10 cos 30 - 1.5 = (6.0) (Acceleration)
Acceleration = 1.19 m/s^2 = 1.2 m/s^2
