Answer:
By suspending the needles on in the air, the needle which orients itself in the north-south direction is magnetized
Explanation:
- The only method to check a magnet individually without the help of another magnet or magnetic substance on the earth is by suspending it in the air which orients itself in the direction of the magnetic field of the earth.
- This is when the non-magnetic needle will not align itself as the magnetic needle does in the magnetic field of the earth.
Answer:
Norma’s average speed is 41.9 km/h.
Explanation:
The average speed is given by:
![\overline{v} = \frac{d_{T}}{t_{T}}](https://tex.z-dn.net/?f=%20%5Coverline%7Bv%7D%20%3D%20%5Cfrac%7Bd_%7BT%7D%7D%7Bt_%7BT%7D%7D%20)
Where:
: is the total distance
: is the total time
We can find the total distance as follows:
Now, the total time is:
Hence, the average speed is:
![\overline{v} = \frac{d_{T}}{t_{T}} = \frac{289 km}{6.9 h} = 41.9 km/h](https://tex.z-dn.net/?f=%20%5Coverline%7Bv%7D%20%3D%20%5Cfrac%7Bd_%7BT%7D%7D%7Bt_%7BT%7D%7D%20%3D%20%5Cfrac%7B289%20km%7D%7B6.9%20h%7D%20%3D%2041.9%20km%2Fh%20)
Therefore, Norma’s average speed is 41.9 km/h.
I hope it helps you!
