There was a supercontinent called Pangea
Answer:
(D) energy from one place to another
sorry if i'm mistaken but i'm pretty sure its A) Y
Answer:
where are the statements so i can see which one is correct
Explanation:
Answer:
momentum =0
kinetic energy >0, positive
Explanation:
The final momentum is zero but the final kinetic energy is positive.
The momentum is zero because momentum is the sum of the mass×velocity for each component. momentum is conserved
The KE is positive because KE is the sum of the 1/2×mass×velocity^2.
Whereas velocity can be positive and negative since it is (it's what makes the momentum zero because on is positive and one is negative), the velocity squared will always be positive.
Adding together two positives will always be a positive number.
