How would you describe the interaction between opposite (n-s or s-n) magnetic poles?

they repel each other.

they are attracted to each other.

they create a magnetic field from s to n.

there is repulsion between n and s poles.

no magnetic field exists between the magnets.

The correct answer is they are attracted to each other.

Explanation:

There are 2 poles of a magnet: North and South pole.

When two same poles come closer to each other, they are repelled by each other. North and North pole will repel each other and likewise with south pole.

When two different poles come closer to each other, they are attracted to each other. North and South pole with attract each other.

We are asked the interaction between two opposite poles, so the correct answer is that they are attracted to each other.

answer is b

Explanation:

b

explanation:

bc its just b

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
