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?
The initial velocity needed can be calculated using the conservation of energy principle. The gravitational potential energy at height 20m is equal to the initial kinetic energy given to the mass. Using the equation for gravitational potential energy (mgh), where m = mass, g = acceleration due to gravity (9.81 m/s²), and h = height (20m), we can calculate the initial velocity. The total energy of the system will be the sum of the initial kinetic energy and the potential energy at height 20m.
What is the energy loss formula used to calculate the amount of energy dissipated in a system?
The energy loss formula used to calculate the amount of energy dissipated in a system is typically given by the equation: Energy loss Initial energy - Final energy.
How does electricity give off energy?
Electricity gives off energy through the flow of electrons in a circuit. When electrons move through a conductor, they can transfer energy in the form of heat, light, or mechanical motion depending on the device or appliance being used. This flow of electrons generates energy that can be harnessed for various applications.
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.
A force of 315N is applied to a crate to displace it 35m across a floor at constant velocity The internal energy increases by 14percent of initial internal energy what was the initial internal energy?
1543.5 is the answer w=F*s = 315*35 =11025 this is the final or total internal energy now use the formula of percentage 14/100=initial internal energy/11025 (14/100)*11025=internal energy i cannot say with surety that this is right
When electrons lose energy and return to their initial or ground state what is given off?
Light.
When excited electrons radiate energy the amount of energy given off is equal to?
The amount of energy given off by excited electrons when they radiate energy is equal to the difference in energy level between the initial and final states. This emitted energy is typically in the form of photons.
What is the amount of energy given off or absorbed when electrons change energy states equal to?
The amount of energy given off or absorbed when electrons change energy states is equal to the difference in energy levels between the initial and final states of the electron. This energy is typically released or absorbed in the form of electromagnetic radiation, such as 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 you put an element in a flame you see different colors of light given off How why?
The heat of the flame provides thermal energy which can excite the electrons in the atom to higher energy levels. When the electrons 'relax' down to their ground state the excess energy is given out as radiation. For it to be coloured, the radiation must fall in the visible spectrum.
What is the definition of high energy electrons and how do they impact the behavior of particles in a given system?
High energy electrons are electrons that possess a significant amount of kinetic energy. In a given system, these electrons can impact the behavior of particles by colliding with them, transferring energy, and causing ionization or excitation. This can lead to changes in the chemical reactions, radiation emission, and overall dynamics of the system.
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 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?
The initial velocity needed can be calculated using the conservation of energy principle. The gravitational potential energy at height 20m is equal to the initial kinetic energy given to the mass. Using the equation for gravitational potential energy (mgh), where m = mass, g = acceleration due to gravity (9.81 m/s²), and h = height (20m), we can calculate the initial velocity. The total energy of the system will be the sum of the initial kinetic energy and the potential energy at height 20m.
How many electrons can the p orbital in a given energy level hold?
The p orbital can hold a maximum of 6 electrons in a given energy level.
