The structural of the unicellular organism and the multicellular organism differs in a broad variety of ways. The main differences you need to know between these two cells are the following.
- Unicellular organism is composed with only one cell.
- Multicellular organism is made up of two or more cells.
- Unicellular are mostly prokaryotes, while multicellular is mainly considered as eukaryotes.
- Unicellular organisms are more smaller and less complex than multicellular organisms.

Answer:
A: The frequency of the vibration is 1.3329 Hz
B: The total energy of the vibration is 18.39375 J
Explanation:
The force of the man his weight causes the raft to sink, and that causes the water to put a larger upward force on the raft. This extra force is a restoring force, because it is in the opposite direction of the force put on the raft by the man. Then when the man steps off, the restoring force pushes upward on the raft, and thus the raft – water system acts like a spring, with a spring constant found as follows:
k= F/x = ((75 kg) * (9.81 m/s²))/(5*10^-2 m) = 14715 N/m
The frequency of the vibration is determined by the spring constant (k) and the mass of the raft (210kg).
fn = 1/2π * √(k/m) = 1/2π * √(14715 / 210) = <u>1.3329 Hz</u>
<u>The frequency of the vibration is 1.3329 Hz</u>
<u />
<u>b) </u>
Since the gravitational potential energy can be ignored, the total energy will be :
Etot = 1/2 k* A² = 1/2 * (14715 )*(0.05)² = 18.39375 J
<u>The total energy of the vibration is 18.39375 J</u>
Answer:
B
Explanation:
D is nonsense. The current keeps coming through all lights.
A is wrong. The exact opposite happens. More bulbs more resistance.
C is wrong. More resistance less current, not more.
So your answer is B because the voltage drop in each decreases when there are more bulbs.
