Answer: 
Explanation:
In the image  attached with this answer are shown the given options from which only one is correct.
The correct expression is:

Because, if we derive velocity  with respect to time
 with respect to time  we will have acceleration
 we will have acceleration  , hence:
, hence:

Where  is the mass with units of kilograms (
 is the mass with units of kilograms ( ) and
) and  with units of meter per square seconds

Answer:
correct answer is Fall slide, slump, creep, flow
Explanation:
solution
we know that Movement of particle under the influence of gravity
so rock and other material move down as gravity.
first rock particle fall down because falls occur very rapidly with high slope after that they slide on the slope and after sliding they slump and it occurs when the rupture surface is curved after slump process they creep.  
after creeping, it can flow particle as it occurs slowly with the low slope with water.
so correct answer is Fall slide, slump, creep, flow

Both carts experience the same force but Cart A has a greater speed after the recoil.
The given parameters;
- <em>Mass of the cart A = 0.4 kg</em>
- <em>Mass of the cart B = 0.8 kg</em>
Apply the principle of conservation of linear momentum to determine the velocity of the carts after collision;
 
According to Newton's third law of motion, action and reaction are equal and opposite. The force exerted on cart A is equal to the force exerted on cart B but in opposite direction.

Thus, the correct statement that compares the motion and forces acting on the two carts is "Both carts experience the same force but Cart A has a greater speed after the recoil."
