Answer:
The answer to your question is: after two hours there will be 6400 cell/ ml
Explanation:
Data
Bacteria t = 0; 400 cells/ml
generation time = 30 minutes
# cells after two hours = ?
# of bacteria time
400 0
800 30 min
1600 60 min
3200 90 min
6400 120 min
Answer: A scenario often presented to introductory physics classes is that of a "gravity tunnel" — a tube drilled from one side of the Earth to the other through the planet's center. The answer taught for nearly a half-century for how long a fall through such a hole would take was about 42 minutes and 12 seconds.
Explanation: However, solar and lunar gravity, which also perturb orbiting satellites, would eventually pull you into the tunnel wall anyway [source: Darling ]. Strike a chord: Fun fact: A straight line from any point to any other point through the planet would take the same amount of time to fall through like a tunnel through Earth's center.
