Which of the following best describes the magnetic field lines around an isolated, permanent bar magnet?A. The field lines go from the magnet's south pole into its north pole.
B. The field points out along radial lines from the bar magnet, extending straight out to infinity.
C. The field lines go from the magnet's north pole into its south pole.
D. The field points straight into the bar magnet along radial lines that extend to infinity.
Answers
Option C. The field lines go from the magnet's north pole into its south pole.
The magnetic field lines of a magnet always emerge from its North pole and enter back in the south pole, as shown in the image attached with.
Therefore, option C is the correct answer
Answer:
c

DISTANCE
-length of the path between two points
-doesn't have to be a straight path
-has no direction
DISPLACEMENT
-the length from the starting point to the ending point
-must be a straight path
-must have direction (north, south, east, west, up, down)
EXAMPLE-If you wanted to know the distance from your house to the park, you could say 'three blocks north and then two blocks west' but for displacement, you could just cut through houses and backyards to get to the destination.
Hope that makes some sense :)

Answer:
Kinetic energy of the shot is 400 Joules
Explanation:
It is given that,
Mass of the shot, m = 8 kg
Speed of thrown, v = 10 m/s
We have to find the kinetic energy of the shot. It is given by the product of mass of an object and the square of velocity divided by 2 i.e.
KE = 400 Joules
Hence, the kinetic energy of the shot is 400 joules.
