.05 is larger than .005 because larger numbers are always to the left and smaller numbers are always to the right
Answer:
Last choice
Step-by-step explanation: Subtract 11 and then divide by 3. A would be greater than -2 and last choice shows that
x is -31 because you had to add -11 and -20
Answer:
Trial- 2 shows the conservation of momentum in a closed system.
Step-by-step explanation:
Given: Mass of balls are 
Conservation of momentum in a closed system occurs when momentum before collision is equal to momentum after collision.
- Let initial velocity of ball

- Initial velocity of ball

- Final velocity of ball

- Final velocity of ball

- Momentum before collision

- Momentum after collision

Now, According to conservation of momentum.
Momentum before collision = Momentum after collision

We will plug each trial to this equation.
Trial 1

Trial 2

Trial 3

Trial 4

We can see only Trial 2 satisfies the princple of conservation of momentum. That is momentum before collison should equal to momentum after collision.
