Alarge-scale wind turbine has blades of 104 min diameter and is rated at 3.6 mw.
a. if 20 percent of the kinetic energy of the wind incident on the blades is converted into work, what wind speed is needed to produce 3.6 mw of power? (note
that the average wind speed in most of georgia is less than 5 m/s)
b. since we are converting between kinetic and mechanical energy, do you think it’s possible to achieve 100 percent efficiency?

Ithink 2 is the correct

First up write the aim
then write the materials reqd.
then the procedure which you follow
then observation
then conclusion
then you can write lab safety rules or precautions(you can avoid if u want).
lemme' give an example
aim: to observe the double displacement reaction
materials reqd: bacl2 and na2so4, test tubes and a dropper
procedure:
1. take bacl2 in a test tube and na2so4 in the other.
2. then pour bacl2 into na2so4 solution.
3. observe
observation:
you will see that a white precipitate is formed called baso4. along with that common salt or nacl is formed.
the equation is
bacl2+na2so4=baso4+2nacl
conclusion:
a double displacement reaction is observed.
hope it
