(explain why) a bar magnet is dipolar. this means is has poles.
a. zero
b. one
c. two
d. three

Two poles

Explanation:

The word dipole can be splitted to two; "di" and "pole"; di means 2; hence dipole means 2 poles

A dipolar bar magnet has two poles on the earth surface; these poles are the geomagnetic north pole and the south pole respectively.

In other words, a dipole magnet is a type of magnet in which the opposite poles (which are the North and South poles) are on opposite sides of the magnet.

Away from the surface the dipole becomes distorted. The magnetic field of a bar magnet has a simple configuration known as a dipole field.

unbalanced force

explanation:

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
