Answer:
single replacement
Explanation:
In the question it says one element replaces another element which means there is only one replacement.
Answer:
Sometimes called "the breadbasket of America" the Midwest serves as a center for grain production, particularly wheat, corn and soybeans. Graham bread, steamed cornbread, and johnny cakes are traditional Midwestern foods, as are butter cakes like chocolate cake, devil's food cake, coconut cake and fruit cake
Answer:
0.312 m/s
Explanation:
Elastic collisions conserve momentum and kinetic energy
The velocity of the center of mass will not change. It continues at
0.00521(443) / 14.80521 = 0.155893... ≈ 0.156 m/s
To conserve kinetic energy we can think of the center of mass (CoM) as an ideal spring returning to each mass that strikes it an identical speed of collision in the opposite direction.
The CoM sees the target approach at - 0.156 and will see it depart at 0.156 m/s
A ground based observer sees the target depart at the velocity of the CoM plus the relative velocity .
v = 0.156 + 0.156 = 0.312 m/s
Answer: 5.29 seconds
Explanation:
if the speed is 24 meters per second than it would take you 5.29 seconds or 127meters/24m/s to get 5.29s
