Answer:
1.40 m/s^2
Explanation:
Given data
Velocity= 17.4 m/s
time= 12.4 seconds
We want to find the acceleration of the rock
We know that
acceleration = velocity/time
Substitute
acceleration= 17.4/12.4
acceleration=1.40 m/s^2
Hence the acceleration is 1.40 m/s^2
Answer:
A
Explanation:
An object in motion will stay in motion unless acted upon by an external force.
Say you rolled a ball on the ground, eventually it will stop because of friction and gravity
<span>The correct answer is: Oxygen
Explanation:
In order to function properly (movement etc.) during exercise, muscles require oxygen. During exercise, the depth as well as the rate of breathing increase, which in turn increases the amount of oxygen inhaled. In order to expand and contract lungs and for other bodily movements, muscles require oxygen, and for that, more oxygen is carried in the blood to muscles. Hence, the correct answer is Oxygen.</span>
A stratovolcano is a conical volcano consisting of layers of solid lava flows mixed with layers of other rock.
A cinder cone volcano doesn’t have any horizontal layers, and is instead a steep conical hill of tephra that accumulates around and downwind from the vent.
