Answer:
Yes, the frequency of light emitted is a property of the difference between the levels of energy of its electrons.
Explanation:
Neon atom is a noble gas which glows when its electrons de-excites after absorbing energy.
Niels Bohr postulated that the energy level in all atoms are quantized, thus electrons do not exist in-between two levels. When electrons in the Neon atom are excited, this increase in energy causes them to jump to a higher energy levels. On de-excitation, the electrons drops to their initial level releasing the absorbed energy in the form of a photon.
The photon emitted has a frequency that is directly proportional to the energy change in the electron.
The net force acting on the two (2) kids is equal to 180 Newton.
<u>Given the following data:</u>
- Mass of kid 1 = 40 kilogram.
- Mass of kid 2 = 50 kilogram.
- Acceleration = 2
To determine the net force acting on the two (2) kids:
First of all, we would calculate the total mass of the two (2) kids:
Total mass = 90 kg.
<h3>
How to calculate net force.</h3>
In this exercise, you're required to calculate the magnitude of the net force that is acting on these two (2) kids running down the hall. Thus, we would apply Newton's Second Law of Motion.
Mathematically, Newton's Second Law of Motion is given by this formula;
Substituting the given parameters into the formula, we have;
Net force = 180 Newton.

The gravitational potential energy as a rollercoaster converts to kinetic energy when it moves downhill.
<h3>
What is kinetic energy?</h3>
The kinetic energy of an object or body is due to its motion. When the roller coaster moves downhill it accelerates, thus the gravitational potential energy as a rollercoaster converts to kinetic energy.
The gravitational potential energy of an object or body is due to its position above the ground.
Therefore, the gravitational potential energy as a rollercoaster converts to kinetic energy when it moves downhill.

Solid carbon is an element in its solid state, not a mixture.
Carbon-dioxide gas is a compound in its gaseous state, not a mixture.
Liquid copper is an element in its liquid state, not a compound.
Copper will never dissolve in water, so copper in water is a mixture.
Answer:
X=m*g/K
Explanation:
Since the elastic force of the spring is balancing the force of gravity:
Fe = m*g
Now, on the spring by Hook's law, the magnitude of the elastic force will be:
Fe = K*X where K is the elastic constant of the spring and X is the distance the spring is strectches measured from its original lenght to its current length.
Replacing this value:
K*X = m*g Solving for X:
X = m*g/K This value is directly proportional to the object's weight and inversely proportional to the spring's constant.
