what the difference between trade discount and cash discount
how can we protect a magnet from loosing its magnetism?
Storing it away from strong electric and magnetic field
can you explain more about motion in straight line???
Motion in a straight line is the same as linear motion
The kilowatt-hour is a unit of energy equal to 3600 kilojoules. The kilowatt-hour is commonly used as a billing unit for energy delivered to consumers by electric utilities.
Use the domain theory to explain the difference between magnetic and non-magentic materials
The magnetic materials are attracted to an external magnetic field due to their proper alignment of magnetic domains whereas non-magnetic materials are repelled from an external magnetic field due to their random arrangement of magnetic domains.
What does the domain theory state
The domain theory states that inside a magnet there are small regions in which the magnetic direction of all the atoms are aligned in the same directions.
What's measurement
Is the process of assigning numerical values to things so that you can find their size and magnetude
What are the six properties of all magnets
1.magnet attracts magnetic materials
2.magnetic force is stronger in the magnets poles
3like poles repels and unlike poles attracts
4.in a moving magnet the north poles points the south and likewise the south pole
5.the magnetic force is the action in a distance force
Curved lines used to represent a magnetic field
