Dna is the way to answer this questions
Answer:
B. They show the pattern made by the magnetic field lines around the
magnets
Explanation:
Using iron fillings, the pattern of the magnetic field lines around a bar magnet can be known.
Magnetic field lines are the line of force around a bar magnet.
- These iron fillings will trace the pattern of the magnetic field around the magnet.
- The domains of the iron fillings begins to align and orient with that of the prevailing magnetic field around.
- Those areas with the strongest force will attract more fillings and those far away will attract lesser fillings.
Answer:
speed
Explanation:
The slope of a line on any distance-time graph represents the speed of the object.
Velocity only comes in when there is speed of the object in a particular direction.
Displacement = (final position) - (initial position) = change in position.
