The more diverse an ecosystem is —

A. the more threatened its populations are
B. the more similar the species will be
C. the more sustainable it is
D. the fewer varieties of species are present

Answers

Answer 1

The correct answer is C: the more sustainable it is

Answer 2

When the more diverse an ecosystem is so here the option b is selected i.e. the more similar the species will be.

What is an ecosystem?

An ecosystem comprises of all type of organisms and the physical environment in which they interacted.

These biotic and abiotic components are connected together via the nutrient cycles and flow of energy.

So when the ecosystem is more diverse so the species should be more similar.

Hence, the option b is correct.

What is the kinetic energy of a 4,000 kg elephant that is running at 2 m/s? What is the kinetic energy of the elephant if it running at 4 m/s? How do the two kinetic energies compare with one another?

How do the two kinetic energies compare to one another? QUADRUPLES !

#3 What is the kinetic energy of a 2,000 kg bus that is moving at 30 m/s?

Potential energy

By definition of kinetic energy,

the kinetic energy of a 4,000 kg elephant that is running at 2 m/s is 8000 Jthe kinetic energy of a 4,000 kg elephant that is running at 4 m/s is 32000 Jthe kinetic energy at a speed of 4 m/s quadruples with respect to the speed of 2 m/s.

Kinetic energy is a form of energy. It is defined as the energy associated with bodies that are in motion and this energy depends on the mass and speed of the body.

Kinetic energy is defined as the amount of work necessary to accelerate a body of a given mass and at rest, until it reaches a given speed. Once this point is reached, the amount of accumulated kinetic energy will remain the same unless there is a change in speed or the body returns to its state of rest by applying a force.

Kinetic energy is represented by the following expression:

Ec = ½ mv²

Where Ec is kinetic energy, which is measured in Joules (J), m is mass measured in kilograms (kg), and v is velocity measured in meters over seconds (m/s).

In this case, you know:

m= 4000 kgv1= 2 m/sv2= 4 m/s

Then:

Ec1 = ½ mv1²

Ec1=  ½ 4000 kg× (2 m/s)²

Ec1= 8000 J

and

Ec2 = ½ mv2²

Ec2=  ½ 4000 kg× (4 m/s)²

Ec2= 32000 J

You can see that the kinetic energy at a speed of 4 m/s quadruples with respect to the speed of 2 m/s.

In summary:

the kinetic energy of a 4,000 kg elephant that is running at 2 m/s is 8000 Jthe kinetic energy of a 4,000 kg elephant that is running at 4 m/s is 32000 Jthe kinetic energy at a speed of 4 m/s quadruples with respect to the speed of 2 m/s.
