What is the initial velocity that must be given to a 1kg mass if it is to move to a height of 20m. what is the total energy?
After 20 m all kinetic energy have been transformed to potential energy.Epot=m*g*h=0.15*9.81*20=29.4 Joule
How does electricity give off energy?
Electrons are given energy because of the work done by the attractive or repulsive force, when they reach the place where they meet positive charges, they give off (release) their energy.
What happens when an electron emits a photon?
When an electron absorbs a photon, the energy it gains can cause it to change orbitals. The result is ionization. The electron can then emit a photon in the process of "falling back" into its original orbit. Note that electrons won't absorb a photon that cannot give them enough energy to reach a higher orbital. There are no "half measures" in this aspect of quantum mechanics as electrons cannot be shifted "half way" to the next higher orbital. The proof of the pudding here is that we can use lasers of a given frequency to stimulate the electrons in orbit around given atoms. By knowing how much energy a certain electron needs to move to the next higher orbital, we can tune our laser to that photonic energy. Then when we point our laser at a bunch of these atoms, we'll see a bunch of electrons being kicked up to higher orbitals and then emitting photons to return to their previous orbital. There is a bit more to this, but the essentials are here, and are a first step to understanding the subtle ways photons and electrons interact.
How much do you decrease your kinetice energy when you decrease your speed by double?
Kinetic energy is given by mv2, where m is mass and v is speed. To obtain a result let me divide the new kinetic energy, m(v/2)2 (where the initial velocity is divided by two), by the initial velocity, mv2. (v2/4)/v2 = 1/4 The kinetic energy will be one fourth of what it was when the speed is halved.
Which sublevel will contain electrons with the greatest energy?
Among all the subshells present in a given shell, f-subshell has the highest energy.
When electrons lose energy and return to their initial or ground state what is given off?
Light.
What is given off when electrons return to their ground state?
energy is given out. this is emitted in the form light ie each atom has its own characteristic emission spectra.
Is energy given or taken off with electrons?
It is given off
What is the emission of electrons from a metals surface?
the external energy given to electrons,thier kinetic energy increases.thus electrons move from metal surface
When excited electrons radiate energy the amount of energy given off is equal to?
Photons
A spectroscope measures the light energy given off by?
orbital electrons
How many electrons cana s orbital of a given energy level hold?
Two electrons of opposite spin
What is the amount of energy given off or absorbed when electrons change energy states equal to?
E=hv
What is givin off when electrons in an atom fall to a lower orbit?
Energy (in the form of photons) is given off when electrons in an atom fall to a lower energy level.
What is the name given to the electrons in the highest ocupied energy level of an atom?
These electrons are called "valence" electrons. They are the ones that take place in bond formation.
Light given off by an atom is its what?
it is its energy emitted by electrons while moving from higher energy state to lower one.
How many electrons are there in 1234567 shell?
The number of electrons that are possible in a given energy level is given by the formula 2(n2), where n is the energy level. So you square the energy level and multiply times two. This gives you the electron capacity for that energy level. For example, the possible electron capacity for energy level 6 is 2(62), which is 2 x 36, which is 72. So the 6th energy level can take a maximum of 72 electrons.
