The general tendency has been to use more energy per capita over time.
In a closed system, energy cannot be lost but it can be transferred or transformed, leading to a dissipation of energy over time. This can occur through processes like heat transfer, friction, or chemical reactions, which result in the conversion of energy to forms that are not available for further use in the system.
Power is the rate at which energy is transferred or transformed over time. It is measured in watts (Joules per second) and indicates how quickly work is done or energy is used. Mathematically, power is calculated as the energy transferred or used divided by the time taken.
A 600W drill would use 600 joules of electrical energy in one second (since 1 watt = 1 joule/second). To calculate the total energy used over a specific period of time, you would multiply the power in watts by the time in seconds.
Energy is not infinite; there is a limit to its availability. The Earth has finite resources that can be used to generate energy, and these resources can be depleted over time. It is important to use energy efficiently and explore renewable sources to ensure a sustainable future.
converted from one form to another. For example, when electricity is generated in a power plant, the chemical energy in the fuel is converted to electrical energy. Similarly, when you consume food, the chemical energy stored in the food is converted to mechanical energy for your body to use.
it has changed over the time because now we have plastic stuff and we don't use pottery as much
over time the handykapped people have the good use of a ramp
The ozone issue has changed with time. The use of CFC first depleted the ozone but now it is stable.
Yes. Chemical energy, changed to heat energy, changed to mechanical energy.
What started out as a convenience is now a necessity.
air craft
because it went from rollers to electrical irons that are easier to use
you used to have to wind them up and now they use three micro chips
its changed over time by tectonic plates shifting.
the use of basketball has changed over time because it was once just a sport for ymca athletes but now its used for fitness and to entertain us
the camera has changed in shape in use. the camera is also a video camera and is now used on phone ipods and more . The 'dude' who wrote this ^^^^^^. Spelled camera wrong.... HAHHAHAHHAHAH. DO NOT use information from him.
Maybe, but it does get hotter over the billions of years. Right now if I can remember it is getting hotter by 30%.
