Which of the following correctly describes the relationship between speed and velocity?
rodikova [14]
Speed and velocity is a scalar and vector quantity of a similar parameter, respectively. They both refer to how fast an object moves. However, the speed only has to do with the magnitude. The velocity takes into account the sign which indicates the direction of the movement. For example, the value is -5 m/s. The speed is 5 m/s, but the velocity is 5 m/s moving downwards because the negative sign denotes downward movement or movement to the left.

a magnet has a north and south pole labeled in the drawing student A thinks that if you cut a magnet in half each ew parts will
riadik2000 [5.3K]

Answer:

The student is Incorrect

Explanation:

Even if you break a magnet the poles still remains same. There is no

difference in the magnet Both north  and south pole will be there even if you

cut it in to small pieces when you cut it into pieces, if suppose you  break 2

magnets and put north and north together it will repel whereas if there  are  

different  poles like north and south it will attract, so even if you break one

single magnet the different poles will attract, Hence the student is incorrect.

Please mark me as brainliest

<h3><u>Thank you </u>:)</h3>
