Answer:
The answer to your question is: v = 121.46 m/s
Explanation:
Data
h = 30 m
vo = ?
dx = 300 m
Formula
t = 
speed = distance / time
Process

t= 2.47 s
speed = 300 / 2.47
speed = v = 121.46 m/s
Yes, as long as it hasn't reached its maximum speed. Think of a car going 30mph, it can remain at this speed and travel at a constant rate; however, the car could also increase it's speed further. Hope this answers your question.

Answer:
The time required for sucrose transportation through the tube is 8.4319 sec.
Explanation:
Given:
L = 0.025 m
A = 6.5×10^-4 m^2
D = 5×10^-10 m^2/s
ΔC = 5.2 x 10^-3 kg/m^3
m = 5.7×10^-13 kg
Solution:
t = m×L / D×A×ΔC
t = (5.7×10^-13) × (0.025) / (5×10^-10)×(6.5×10^-4)×(5.2 x 10^-3)
t = 8.4319 sec.
