Answer is B) One swims freely and the other often lives attached to a hard surface.

Nektons are marine aquatic actively-swimming organisms. Nektons propel in the water column freely either by swimming or other by means. Examples include vertebrates such as fish, whales, turtles, sharks and invertebrates include squads.

Benthos are the animals which are found at the bottom of the seafloor. These animals can be free moving forms near the ocean bed or attached to the seafloor. Unlike the nektons, benthos cannot swim in water. Benthos mainly includes echinoderms, crustaceans, molluscs, poriferans and annelids.

What is the Mechanical energy when
Scilla [17]

Answer:

ME = 20 * m, where m is the mass of the pendulum

Explanation:

As we know that mechanical energy is the sum of kinetic energy and potential energy.

Since the Pendulum at its highest point has zero velocity, its kinetic energy at this point is equal to zero.

Thus, here in this mechanical energy will be equal to the potential energy only.

Potential energy is equal to the product of gravity constant, mass of the body and the height of the pendulum

Thus,

ME = PE\\

PE = m * g* h\\PE = 10 * 2* m\\

PE= 20m

Hence,

ME = 20 * m
