Explain how a beam of light passing through a diffuse cloud may give rise to both absorption and emission spectra?
When a light passes through a diffuse cloud, part of the light will be reflected, part will be absorbed, and the rest will pass through depending on the density of the cloud and the energy of the light.The light's energy can be expressed by: E = h(Planck's constant)*nu(frequency)
Why does a bulb glow when electric passes through it?
The filament in the bulb has resistance. The current flowing through the resistance of bulb causes the filament to dissipate energy in the form of heat and light. The filament is actually glowing white-hot because of the energy it is dissipating, thus giving off light.
How is energy released from fossil fuels?
Fossil fuels must be burned to release their energy.
As a cold front passes barometric pressure should?
It will rise after the front passes.
Why does a balloon get smaller in cold weather?
The simple answer is because the pressure remains the same. When pressure remains constant, the change in volume will be directly proportional to the change in temperature. The air molecules release energy as they travel around inside the balloon. What we call pressure is technically the force of the air molecules colliding with the inside of the balloon and each other. The kinetic energy is related to the speed of the molecules. The faster the molecules are moving, the greater the kinetic energy. The greater the kinetic energy, the greater the pressure in the inside of the balloon. The outside air is doing the same thing to outside of the balloon. Therefore, the pressure pushing out is equal to the pressure pushing in. Temperature decreases because the molecules inside the balloon are releasing their energy in the form of heat as they interact with each other. In fact, they heat energy passes through the balloon and is absorbed by the air on the outside. Over time, more energy is released, and the temperature drops. The volume of the balloon decreases in order to maintain a constant pressure. As the surface area decreases, the total pressure pushing in also decreases so that it always equals the pressure pushing out.
Why is there a change in rate of energy exchange as time passes?
There is a change in rate of energy transfer as time passes because of the amount of energy in both objects. -probably wrong
Does energy change when it passes through a light bulb filament?
The energy won't change
How does energy change when it passes through a light bulb filament?
The energy won't change
In gas exchange what passes from the blood to the alveoli?
Oxygen
What happens as blood passes each cell?
Gas exchange.
What passes through a medium?
energy is independent of medium it passes through?
Does light's Energy Decreases as it travels from air into water?
No the Energy of the light doesn't change when it passes through rarer to denser medium. Only Wavelength changes which cause change in its direction. Since Frequency is directly proportional to the Energy and frequency is constant during refraction therefore the energy also remain constant.
What happens to its potential energy as it passes to the lowest point?
potential energy changes to kinetic energy
Why does pressure not change when viscous fluid passes through varying cross sectional area?
I am satisfide that the pressure should be changed according to Energy Ballance equation
How does the oxygen change to carbon dioxide?
The primary function of the respiratory system is to exchange oxygen and carbon dioxide. Inhaled oxygenenters the lungs and reaches the alveoli. Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled.
What is the job of the respritory system?
the respiratory system passes the air you breathe into the lungs for gas exchange .
Can you exchange horses for items on Howrse?
Not really, but you can sell horses for equass and passes then buy the item.
