How do photons create electrons?
Photons create electrons in two senses. In the first sense, they don't really create electrons but eject them: from a surface in the photo-electric effect or from atoms or molecules in photo-ionization. Observing the photo-electric effect was a key part of discovering quantum mechanics. In the second sense, an electron is created together with its anti-particle, a positron, when the photon collides with another particle. Particle-antiparticle creation requires a lot more energy than "photo-ejection". This is conversion of energy into matter, in this case matter with a rest mass of just over a million electronvolts (in mass-equivalent units according to Einstein's E=mc^2). So the photon (and target particle) need to have kinetic energy of that amount for electron-positron pairs to be created.
Is Energy can be change completely from one form to another?
Usually not; some energy is usually wasted. Although energy can't really be destroyed, part of the energy is converted to an unusable form.Usually not; some energy is usually wasted.

What process creates energy within the sun?
Nuclear fusion is the process that creates energy within the sun. During nuclear fusion, hydrogen atoms combine to form helium, releasing vast amounts of energy in the form of heat and light. This process is sustained by the immense gravitational pressure at the sun's core.
Which form of energy would be hard to get on a cloudy day?
Solar energy. For example, our solar stove doesn't really get hot when it is cloudy.Solar energy. For example, our solar stove doesn't really get hot when it is cloudy.Solar energy.

What type of energy is occurring with a rainbow?
A rainbow is not a physical entity; it's basically an illusion, so you can't really say that it has properties such as energy. The raindrops that create this illusion do have a certain amount of gravitational potential energy.
Why is important to conserve energy?
In the long run, everyone conserving as much energy as possible can really create a change. REDUCE, REUSE, RECYCLE!!!!!!
What creates the suns light and heat energy?
Nuclear fusion. Enormous pressure near the sun's center causes atoms of hydrogen to fuse together and form helium atoms releasing tremendous amounts of energy- put really simply. ALL stars use the same method to create heat and energy.
Is potential energy used in fireworks?
Yes, potential energy is used in fireworks. When the fireworks are ignited, chemical potential energy is converted into thermal energy, which causes the fireworks to explode and create light and sound.
Can gemstones Blue sapphire and pearl be worn together?
Yes, blue sapphire and pearl can be worn together as they complement each other well. Blue sapphire is associated with wisdom and protection, while pearl symbolizes purity and emotional balance. When worn together, they can create a harmonious and balanced energy.
How do Santa Claus and the bussinessman create a strong contrast?
They work A LOT together, so they bond really well.....
What does energy production require?
Well, since you can't really PRODUCE energy (create it out of nothing), you need an energy source. You will really convert an existing type of energy into another one, which is more useful for some purpose.You also need technology to do this energy conversion. What devices you need, will depend on the specific type of energy conversion.
When occurs when hydrogen atoms collide?
They interact with each other chemically or by binding together. When 2 or more atoms combine chemically, they create molecules. When they bind together to create a molecule, it is called a compound.
How to create enough kinetic energy to run an mp3 player?
hi i really need this answer to finish my mastery assessment in collleage its an home experiment where you have to come up wit an experiment to convert energy plz i really need your help Pedal a bike
How do you create static energy or static shocks?
from making high amounts of friction, like when you rub your socks against carpet really fast

How do you get in to a penguin band on Club Penguin?
technically, you can't really sign up for it but you can get some friends together on club penguin and create your own band
What do plants absorb to create the energy they produce?
The equation for photosynthesis is co2+h2o+=c6h12o6+6o2+energy. That sounds complicated, but it's really not. All that means is that to produce glucose, energy, and oxygen (the glucose and the energy are what's needed), a plant needs Carbon Dioxide and water.
