What is the cause of most waves and how can this change waves' characteristics?

Answers

Answer 1

There are three main factors that affect wave formation: wind velocity, fetch, and duration.

Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.

#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.
