Question 2 of 34
1 Point
lan's school is exactly 6 blocks north of his house. What is his average
velocity on a walk from home to school that takes him 12 minutes?
O
A. 6 blocks/min north
O
B. 2 min/blocks
O
c. 0.5 blocks/min north
O
D. 2 blocks/min north

Option C) 0.5 blocks/min north

Explanation:

Distance of lan's school from his house = 6 blocks north

Time taken from lan's house to school = 12 minutes

Average velocity of Ian = ?

Recall that average velocity is the total displacement divided by the total time taken.

Average velocity = (Displacement / Time taken)

Average velocity = (6 blocks north/12 minutes)

= 0.5 blocks/min north

Thus, Ian's walk with an average velocity of 0.5 blocks per minute towards north.

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
