Answer:
d. displacement
Explanation:
Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
When particles in a substance slow down, we can infer that the object is getting colder. Why we can infer this:
1. Kinetic energy, is energy due to motion, therefore if there is no motion, there is no kinetic energy.
2. The colder an object get, the closer it becomes to having it's particles stopping completely, eventually at the absolute zero.
3. As kinetic energy increases, particles move faster. Kinetic energy usually increases when an object gets warmer. As kinetic energy decreases, particles move slower. Kinetic energy usually decreases when an object gets colder.
So, with this information, we now how and why the kinetic energy slows down.
Here is your answer
C. towards the floor
REASON:
Using Fleming's Left hand rule we can determine the direction of force applied on a moving charged particle placed in a magnetic field.
The direction of current will be just opposite to the direction of electron(negative charge) because current moves from positive to negative terminal whereas electron moves from negative to positive terminal.
So, direction of current- North to South
Now applying Fleming's Left hand rule we get the direction of force in downward direction, i.e. towards the floor.

This is the case because the tension is not equivalent to the load's weight, which means there must another force acting on the system.
