There you go again. Newton's 3rd Law says "for every action there is an EQUAL OPPOSITE reaction.".
EQUALand OPPOSITE
If THIS MUCH force pushes the bullet THAT way, then THE SAME amount of force pushes the rifle THIS way.
The bullet pushes backward on the rifle with the same amount of force as the rifle exerts on the bullet.
Non-foliated metamorphic rocks are rocks that have been changed by heat and pressure into rocks with a non-layered or banded appearance. Some examples of non-foliated metamorphic rocks include quartzite, marble, amphibolite and hornfels.

2)the needle of compass line up with earth magnetic field and point to_________
a)earth poles b)earth equator
3)magnetic field lines that curve toward each other show_________
a)repulsion b)attraction
4)some animals have tiny pieces of ___________in their brains to help them find their way
a)magnetite b)magnetosphere
5)a magnet contain a large number of magnetic _____that are lined up and pointed in the same direction.
a)domains b)poles
Answer:
1 . a) the poles
2. a) earth poles.
3. b) attraction.
4. a) magnetite.
5. a) domains.
Explanation:
The magnetic field is strongest at the poles and very weak at the center of the magnet.
The magnetic compass will always align along the north - south poles of the earth. North of the compass needle is attracted towards the magnetic south pole of the earth.
Magnetic Field lines begin at the north pole of the magnet and end at the south pole. Unlike poles attract and like poles repel , so they curve for unlike poles.
Magnetite is a magnetic mineral, which is present in the animal brains , enabling them to identify correct directions.
Magnetic domains are regions where individual magnetic moments of the atoms are aligned in a definite direction.
