What is activiation energy?
activation energy means the power that activates a device
What is a way to show potential energy?
Elevation.
How can a loud speaker make sound energy with electric energy?
It converts the electric energy into vibrations which are sound energy.
How is the wind energy captured by the windmill?
wind makes the mill spin wich motion activates the machinery that sends electricity or other means of energy.
Is the energy in your hair positive or negative?
positive
What is activiation energy?
activation energy means the power that activates a device
When light activates the electrons of chlorophyll then those electrons have a less or more energy?
When the light "activates" the electrons, it kicks them up into higher orbitals where they have more energy. That extra energy is utilized to power the photosynthesis reaction.
A jogger who bounces up and down while running is said to waste more energy than a jogger with a smooth stride whose center of gravity remains at about a constant elevation Why?
For each little 'bounce', the runner has to expend the energy to raise his weight by those few inches ... which gravity immediately reverses as it pulls him down to his original elevation. None of this adds anything to his forward progress. So in the course of the same forward distance, the bouncer expends more total energy than the guy who keeps his center of mass at a constant elevation.
If the energy of an electron is found with Energy equals hc divided by lamda which contains only positive terms how can the energy of a bound electron be negative?
The h in the hc stands for plancks constant which is 6.63 x10^-34, which is negative. :)
What is a way to show potential energy?
Elevation.
What are pumped storage reservoirs?
The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation.
Why does an organism need energy and constant supply of energy?
An organism needs energy and constant supply of materials to grow and develop.
What is Boltzman's constant?
The Boltzman's constant is the physical constant relating to temperature to energy.
What activates chloryphyll?
The chlorophyll on exposure to light energy becomes activated by absorbing photons(photon is the smallest unit of light energy)
What causes positive energy balance and what are the effects of positive energy balance?
Positive energy balance is when energy intake exceeds expenditure weight is gained
Why do you have to conserve energy when infact the energy of this world is constant?
While the TOTAL amount of energy remains constant, on the other hand, useful energy can, and will, be converted into unusable energy.
How can a loud speaker make sound energy with electric energy?
It converts the electric energy into vibrations which are sound energy.
