Solution :
Given :
Operation time, 
= 3000 hours per year
Operation time, 
= 2000 hours per year
The density, ρ = 
The wind blows steadily. So, the K.E. = 
The power generation is the time rate of the kinetic energy which can be calculated as follows:
Power = 
Regarding that 
. Then,
Power 
→ Power = constant x 
Since, 
is constant for both the sites and the area is the same as same winf turbine is used.
For the first site,
Power, 
For the second site,
Power, 
Answer:
Tech A
Explanation:
The amount of energy required to apply the same force with a 1:1 ratio is divided into 4, so you can apply 4 times as much force than a 1:1 ratio. efficiency and speed come into play here, but assuming the machine powering the gear can run at a unlimited RPM, 4:1 will have more force and a slower output speed than a 2:1 ratio.
When a psychologist simply records the relationship between two variables without manipulating them, it is called a correlational study.
The observed relationship does not by itself reveal which variable causes the other. This is the directionally problem. Also, the relationship may be due to a third variable controlling both of the observed variables.
Answer:
An artificial Christmas tree is an artificial pine or fir tree manufactured for the specific purpose of use as a Christmas tree. The earliest artificial Christmas trees were wooden, tree-shaped pyramids or feather trees, both developed by Germans. Most modern trees are made of polyvinyl chloride (PVC) but many other types of trees have been and are available, including aluminum Christmas trees and fiber-optic illuminated Christmas trees.
