Frage 1
Frage
How are birds able to fly? Is it because of...
Antworten
-
Their hollow bones, and the shape of their wings, and the way they flap their wings to generate thrust
-
The way that they generate thrust
-
The way they can glide in the air
Frage 2
Frage
How would you describe the similarities between a bird and a plane? Or, what is the major similarity that the two have? Please give a detailed answer...=D
Frage 3
Frage
What is the greatest difference between a plane and a bird?
Antworten
-
One is an animal and one is a machine
-
One is bigger than the other
-
Birds have feathers, and planes don't
-
Planes are powered by a propeller or a jet engine, whereas birds create their own thrust by flapping
Frage 4
Frage
How are helicopters aerodynamic?
Antworten
-
The shape of the body is aerodynamic
-
The shape of the body is aerodynamic, and the blades slice through the air, and how the air hits the airfoil
-
The way the air hits the airfoil
Frage 5
Frage
Birds have microscopic magnets in their beaks, which allows them to know where they are going while flying. So, it's like birds that migrate have a little compass on/in their beaks. True or false?
Frage 6
Frage
A bird needs feathers to fly because the feathers provide a strong enough surface to catch the wind. Birds also need feathers to keep themselves warm, and protect them from the rain.
