It corrodes the copper by oxydation
Given that,
Initial speed, u = 20 km/s
Acceleration of plane, a = 2.4 km/h²
Time, t = 59 s
We need to find the expression to find the final velocity of an object.Let the final velocity is v.
Using the second equation of kinematics:
a is acceleration,
So,
We can use the above formula to find the final velocity (v) of the plane.
All the 3 resistors below point A and B are in series. These 3 resistors can be replaced by an equivalent resistor of resistance R = 1+1+1 = 3 kΩ
Now, this R and 1 kΩ resistor are in parallel because they have common end points. And they can be replaced by an equivalent resistor of resistance
R' = 3x1/3+1 = 3/4
Answer: As the "wind" pushes the blades and makes them to spin, kinda like an inverse process of how a fan works (where in the fan you impunt energy to make the blades move and generate wind, and in this case the wind makes the blades move to generate electricity), and this movement of the blades creates work that is transformed into electric energy.
Without the wind, you can not generate work in the blades, and then electric energy can not be generated, so you need this source to "push" and impulse torque in the blades.
