What the energy of kinect energy?

Kinetic energy is the energy an object possesses due to its motion. The formula for kinetic energy is KE = 0.5 * m * v^2, where KE is the kinetic energy, m is the mass of the object, and v is the velocity of the object.

What about transformed?

its about to different sides battling echother its really its just good V.S evil but some how we all ways get dragged into it (it being the battle) for a more complex answer go to the Transformers wikia

What is the Harnesses the energy of the sun directly?

Harnessing the energy of the sun directly refers to using solar panels to convert sunlight into electricity through the photovoltaic effect. Solar panels contain solar cells made of semiconductor materials that generate direct current (DC) electricity when exposed to sunlight. This clean and renewable energy source can be used to power homes, businesses, and even entire communities.

What is the energy pathway for a fluorescence source?

In fluorescence, energy is absorbed by a molecule, elevating it to a higher energy state called the excited state. The molecule then emits a photon as it returns to its ground state, producing fluorescence. This process involves the absorption of light energy, internal conversion within the molecule, and the emission of light energy in the form of fluorescence.

What energy can be changed into many different form?

Electrical energy can be changed into many different forms such as heat, light, sound, and mechanical energy through various devices and processes.

What is energy in any physical thing called?

Energy in a physical thing is called internal energy. It is the sum of the kinetic and potential energy associated with the motion and position of the particles that make up the object.

What is Name for Energy stored in the way atoms are connected to each other?

The energy stored in the way atoms are connected to each other is called chemical potential energy. It is the energy stored within the bonds of chemical compounds.

How much chemical energy in 1 apple?

It is estimated that there is approximately 52 calories of chemical energy in an average-sized apple. This energy is derived from the carbohydrates, sugars, and other nutrients present in the fruit that are metabolized by the body to produce energy.

What is the wasted energy output in an electric kettle?

The wasted energy output in an electric kettle is typically around 15-20%. This energy is lost through heat dissipation from the kettle's exterior, inefficient heating elements, and heat lost during the boiling process.

Why does fossil fuels and nuclear plants heat water?

The useful energy we get from fossil fuels and nuclear plants is heat. and heating water to make steam is about the most direct way to capture that thermal energy. Steam is used to spin turbines to turn electric power generators, and that allows us to harness the energy.

What energy does sound turn into?

Sound energy typically gets converted into heat energy as it makes contact with objects or surfaces. This conversion occurs due to the friction and absorption of sound waves by the medium through which they travel.

What is the difference between using nuclear energy and biomass energy?

The main difference is the source of energy generation - nuclear energy comes from splitting atoms in a controlled reaction, while biomass energy is obtained from organic materials like wood, crops, or animal waste. Additionally, nuclear energy is a low-carbon option but raises safety and waste disposal concerns, while biomass energy is renewable but can compete with food production and requires land use.

What is Terminal energy?

Terminal energy refers to the final amount of energy possessed by an object or system at the end of a process or event. It represents the energy state once all other forms of energy have been taken into account or have dissipated. It is often used in physics and engineering to analyze the energy balance of a system.

Why is it good to confirm the information independently when buying a light bulb?

Confirming the information independently when buying a light bulb ensures that you are getting the right specifications for your specific needs, such as the correct bulb size, wattage, and type. This can help avoid purchasing the wrong bulb and having to make a return or exchange later. Additionally, independent confirmation can help verify that you are getting the best quality product for your budget.

How does the human body get chemical energy?

The human body gets chemical energy by breaking down molecules like carbohydrates, fats, and proteins through a process called cellular respiration. This process releases energy in the form of adenosine triphosphate (ATP), which is used by cells for various functions and activities.

How much does hydroelectric energy cost per kw?

The cost of hydroelectric energy production varies greatly depending on factors such as location, size of the project, and construction costs. On average, the cost of producing hydroelectric energy can range from $0.03 to $0.09 per kWh.

What two main states of mechanical energy are what and potential energy?

The two main states of mechanical energy are kinetic energy, which is the energy of motion, and potential energy, which is the energy stored in an object due to its position or condition.

What form of energy does an object get from its motionWhat form of energy does an object get from its motion?

An object gets kinetic energy from its motion, which is the energy of movement. This energy increases as the object's speed or mass increases.

In a nuclear reaction what type of reaction provides the power?

Energy comes from either nuclear fission or nuclear fusion. Each nuclear reaction has unique characteristics, and there are answered questions here that can enlighten an investigator as to the particulars.

What energy conversions take place in order to have energy stored in grass for cows to eat?

The energy conversion starts with sunlight being converted to chemical energy through photosynthesis in the grass. Then, when the cows eat the grass, the chemical energy in the grass is converted to mechanical energy for the cows to move and metabolic energy to sustain bodily functions.

What kind of energy dose a lighter use?

A lighter typically uses chemical energy stored in its fuel source, such as butane, to produce a flame through combustion. When the lighter is ignited, the chemical reactions release the stored energy in the form of heat and light.

What type of energy is Wind moving water and falling rock are examples of?

Wind energy is a type of kinetic energy, as it is produced by the movement of air. Moving water generates hydropower, which is a form of mechanical energy. Falling rock releases potential energy, which then transforms into kinetic energy as the rock falls.

What are the 5 types of artificial energy?

The five types of artificial energy are mechanical energy, thermal energy, chemical energy, electrical energy, and nuclear energy.

Is a rolling marble a kinetic or potential energy?

A rolling marble has kinetic energy due to its motion.

Is a flag blowing in the wind a kinetic of potential energy?

A flag blowing in the wind demonstrates kinetic energy, which is the energy of motion. The wind provides the force that causes the flag to move, resulting in kinetic energy being produced.
