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?

Answers

Answer 1
At 4 m/s?

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
Answer 2

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.

How do the properties of air influence weather?

Answers

Temperature refers to how warm or cold air is, and the density of the air is how many molecules are packed into a certain space of air. ... But, air pressure also affects temperature - the more those molecules bump into each other, the more heat they generate.
Rising Air creates low pressure while sinking air creates high pressure. WIth high pressure, sinking air suppresses weather development. High air pressure produces clear sky, dry and stable weather. In a low pressure zone, wind is circulated onwards and upwards rapidly. As a result, air rise and cools. Clouds and precipitate are formed

What are air masses, and how do they work?

NEED HELP ASAP!

Answers

Answer:

Need help? I'll give it to you!

Explanation:

Air masses are formed when air stagnates for long periods of time over a uniform surface. The characteristic temperature and moisture of air masses are determined by the surface over which they form. An air mass acquires these attributes through heat and moisture exchanges with the surface.

Also known as air-flow mattresses, alternating pressure mattresses relieve and redistribute pressure through a dynamic lying surface. Alternating pressure sore mattresses are assembled with a row of lateral air cells that constantly alternate. Hope it helps

The pressure of a cylinder with the following dimensions: radius 13.9 cm and height 34 cm; has a pressure of 172.9 kPa. If the pressure is reduced to 1.75 atm, what will be the volume of the gas inside the cylinder?

Answers

Answer:Experience has shown that several properties of a gas can be related to each other under certain conditions. The properties are pressure (P), volume (V), temperature (T, in kelvins), and amount of material expressed in moles (n). What we find is that a sample of gas cannot have any random values for these properties. Instead, only certain values, dictated by some simple mathematical relationships, will occur.

Answers

Abiotic factors include the non living components of the environment.
For example- Temperature, humidity, and rainfall.
Desert biome is mainly considered as a part of drylands. It is characterised by extremely low humidity. Average rainfall in this biome is less than ten inches. This results in scarcity of water. It experiences extremely high temperature and is frequently windy.
Example of desert biome- Thar desert in Rajasthan.
