Answer:
85413.20177 W
2050.831684248 kWh
184.5748512 dollars
Explanation:
d = Diameter of blade = 100 m
r = Radius = 
= Efficiency = 0.34
= Density of air = 1.25 kg/m³
V = Velocity of wind = 8 m/s
A = Area = 
The power of a wind turbine is given by
The power is 85413.20177 W
Energy is given by
The energy is 2050.831684248 kWh
The revenue is given by
The revenue generated is 184.5748512 dollars
800/20=40
So the green car would be able to drive 40m
Answer:
Why do scientists usually talk about mass rather than weight? An object's weight is dependent on its mass and how strongly gravity pulls on it. The strength of gravity depends on how far away one object is from another. That's why the same object weighs different amounts on different planets.
Explanation: on Google
<span>208.3 meters
The product of the wavelength multiplied by the frequency will equal the speed of light which is 299792458 m/s. Simple algebra will tell you that you can divide the speed of light by the frequency to get the wavelength. So
224997958 m/s / 1080000 1/s = 208.3314426 m
Rounding to 4 significant digits gives you 208.3 meters.</span>
The elements required for a fire to start are
oxidizing agent, heat, and fuel.
The oxidizing agent is usually oxygen - when there is a lot of air, of oxygen, a fire can broke out more easily if the conditions are right - if there is no oxygen, the fire won't start - we put out a fire by depriving it of oxygen. Next, you need some heat and fuel to start a fire, which can all be seen in this triangle.
