- Q1Wind energy is usually harnessed using ........the Wind Collector 2000Wind turbines and Wind harnessesWindmills and Wind turbinesWindmills and solar panels10s
- Q2Which list depicts in the correct order, how wind turbines produce electricity?1. wind measurement is taken 2. the turbines rotate to face the strongest wind and the blades are angled such that optimum energy is collected 3. the wind turns the blades of the turbine around a motor and the generator begins to spin 4.electricity is produced1. the turbines rotate to face the strongest wind and the blades are angled such that optimum energy is collected 2. wind measurement is taken 3. the wind turns the blades of the turbine around a motor and the generator begins to spin 4. electricity is produced1. the turbines rotate to face the strongest wind and the blades are angled such that optimum energy is collected 2. the wind turns the blades of the turbine around a motor and the generator begins to spin 3. wind measurement is taken 4. electricity is produced10s
- Q3The difference in air pressure across the two sides of the blade creates two forces. These forces are .........lift and tensiondrag and lifttension and normal forcedrag and normal force10s
- Q4When the turbine spins and the the wind flows across the blade, the air pressure on one side of the lade will.....remain the sameincreasedecrease10s
- Q5The rotor of the wind turbine only spins when......lift force is greater than dragdrag force drastically increases hen slowly decreases as the lift force increasesdrag and lift force are equaldrag is greater than lift force10s
