Answer:
223.55 W
Explanation:
v = Velocity of wind = 10 m/s
r = Radius of circle = 5 m
S = Swept area
= Density of air = 1.2 kg/m³
= Power coefficient = 0.593
The maximum possible power that can be produced by the turbine is 223.55 W
Answer:
Mechanical advantage=4
Explanation:
Load=1000N
Effort=250N
mechanical advantage=load/effort
Mechanical advantage=1000/250
Mechanical advantage=4
Answer:
B. 22,22,23,23,22,22,23
Explanation:
The standard deviation is a measure of dispersion or variability of a data set. In order to determine the data set that has the smallest standard deviation, we shall investigate on the ranges of the data sets given. The range of a data set is simply the difference between the maximum and minimum values in a data set. A data set that has a smaller range also has a smaller standard deviation.
From the alternatives given, the data set given by alternative B has the smallest range and consequently the smallest standard deviation.
The maximum value is 23 while the minimum is 22. The range is 1.
Answer:
Distance s=ut+1/2 at^2
If it’s released then this becomes
s=1/2at^2
s=1/2 *9.81*9
s=44.1 m
