The majority of wind turbines consist of three blades mounted to a tower made from tubular steel. There are less common varieties with two blades, or with concrete or steel lattice towers. At 100 feet or more above the ground, the tower allows the turbine to take advantage of faster wind speeds found at higher altitudes.

Turbines catch the wind's energy with their propeller-like blades, which act much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on one side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn. This is called lift. The force of the lift is much stronger than the wind's force against the front side of the blade, which is called drag. The combination of lift and drag causes the rotor to spin like a propeller. So therefore your answer would be A.

6. If 981 mL of a gas is heated from 335 K at constant pressure and the volume
storchak [24]

Answer:

1.5L

Explanation:

The new volume can be found by using the formula for Boyle's law which is

p1v1=p2v2

Since we are finding the new volume

v2= p1v1/p2

From the question we have

v2= 5x3/10=15/10= 3/5

We have the final answer as

1.5 L
