Question 6 is wrong , abd question 10 could be made a bit more clearer, as humans CAN STILL hear between 200 - 20 000hz , i know its at 20hz, the whole quiz in general is a fabulous revision tool

question 6 is wrong. Geo-stationary satellites are used for communication- they always have to move at the same pace of the orbit of the planet thats why they take 24 hours
