30,000-40,000 ft
1000 feet above ground because it's closer to the sun. If you take an object and put it in front of a lamp the closer you put it the bigger the the shadow it will cast
300 x 10 x 2 = 6000 The plane will travel 6000 feet.
In the NBA, the hoop is 10 feet above the ground.
In the NBA, the hoop is 10 feet above the ground.
The observation deck is 520 feet above the ground level.
normally above 10,000 feet and below 41,000 feet above sea level
To find the height of the seesaw when it is level, we need to calculate the average of the two heights. The current heights are 9 feet and 21 feet. The average height is (9 + 21) / 2 = 15 feet. Therefore, when the seesaw is level, both ends will be 15 feet above the ground.
Not unless the plane is in South Africa and about 3 feet above the water...
== == Science Major: Altitude is height above mean sea level (MSL) or true altitude, which means in reference to what sea level is on the ground, or height above ground level (AGL), which is also called absolute altitude, which means height above the ground with no reference to the ground's height above sea level. In example, if the sea level in a certain place is 100 feet and you are 250 feet above the ground, your altitude above sea level would be 350 feet, and your altitude above ground level would be 250 feet.
I think you are thinking of the Russian Ekranoplan, which uses a 'Wing in ground effect' to travel very fast, low over water.
they use plane, cars, and their own feet
Above 10,000 feet, yes.
