This question may require more information to provide a more accurate answer.
A fault block mountain range is formed by tension as rocks are pulled away from each other. A fault block is a section of rock bounded on at least two sides by faults.
Faults commonly break the crust into large, fault bounded blocks. If normal faults down drop one fault block relative to other blocks on either side, the resulting feature is called a Graben.
A block that is uplifted relative to blocks in either side is called a horst.
Kinetic energy = 0.5 * m * v²
m mass
v velocity
If the velocity stays the same and the kinetic energy goes down by a factor of 2, the mass must go down by a factor of 2 also.
Fnet=F1+F2 or Fnet=F1-F2
So 400n up - 600n down
Fnet= 400-600= -200N
Answer:As a noun relative means a person who is connected with others by blood.
