Velocity change v time because ACCELERATION=CHANGE IN VELOCITY/TIME
Answer:
A
Explanation:
Straight line with a negative slope
On a velocity_time graph
During a single replacement, the Zn and H will switch places. That means the product formed will be ZnCl and H2.
The acceleration and distance is related to the following expression:
y=v0*t + a*t^2/2 ; v0=0
y=44.1*100/2 = 2205m
hence, the speed will be
v=0 + a*t = 441m/s
from that height it will just be subjected to the gravitational acceleration
0=v_acc^2 -2g*y_free
y_free = v_acc^2/2g = 9922.5m
<span>y_max = y_acc+y_free = 441+9922.5 =10363.5m</span>
