Answer:
Average acceleration = - 2 m/s^2
Explanation:
Given data:
Initial velocity = 11 m/s
Final velocity = 5.0 m/s
duration of change in velocity = 3 sec
Average acceleration 
Average acceleration 
Average acceleration = - 2 m/s^2
here negative sign indicate that acceleration is proceed in downward direction.
The formula for acceleration is the velocity times the inverse of time so it would be 21 times 1/13. So roughly 0.0769... is the acceleration(m/s^2).
Answer:
A Magnesia
Explanation:
The word magnetism comes from the word Magnesia, which is the name for a region in Asia Minor, where fragments of Fe3O4 ore (magnetite) were found, which attracts other metal objects.
Magnetism is a physical phenomenon by which we describe the attractive or repulsive force between materials.
This phenomenon has been known for thousands of years.
Answer:
