Work with your units:
1 watt-hour = 1 (joule/second) · (hour) = 1 (joule-hour / second)
(1 joule-hour/sec) · (3600 sec/hour) = 3600 joules
So 1 watt-hour = 3,600 joules
Work<span> done is generally referred in </span>relation<span> to the force applied while energy is used in reference to other factors such as heat. </span>Power<span> is defined as </span>work<span> done per unit time. Or energy per unit time. Eg: if you supply 50 joules over a period of 5 seconds, you have supplied 50/5=10 Watts of </span>power<span>.</span>
Answer:
"solar-powered photovoltaic (PVC) panels convert the suns rays into electricity by exciting electrons in silicon cells using the photons of light from the sun. This electricity can then be used to supply renewable energy to your home or business."
I hope this helps ^-^
Explanation:
Answer:
It is constructed with a high mass and a high raidus.
Explanation:
The rotational inertia I for every object is calculated as:
cMR^2 = I
where c is a constant, M is the mass of the object and R the radius of the object.
So, for a flywheel, the rotational inertia is calculated as:
I =
Then, for constructed a flywheel with the maximun rotational inertia we have to set the maximum mass and the maximun radius.
The wind machine on an average operates for a time of about .
Explanation:
The wind energy is the method of using the energy carried by the wind to generate the power. The wind energy is the considered as the conventional and clean source of energy.
The wind machines require the high power winds to rotate the blades of the windmill and produce power using the energy of the moving wind.
The winds blow at such high speed for a very small time during the day, the wind machine cannot be expected to work for a longer time during the whole day.
The wind energy can be obtained form a wind mill for a limited time unlike the other form of energy like thermal energy or even the solar energy. The thermal energy can be obtained at anytime due to burning of fuel whereas the solar energy can at least be obtained during the whole day time.
Thus, the wind machine on an average operates for a time of about .
