Why are fighter jets pointy?
As aircraft travels with subsonic speed it pushes air molecules in front of it. To reduce such type of drag, nose of supersonic aircraft are cone shaped. A pointed nose is more aerodynamic in supersonic flow. This is the reason most of supersonic aircraft have pointed nose.
What is the front of a jet called?
fuselage
What is aircraft maneuverability?
Maneuverability is defined as the ability to change the speed and flight direction of an airplane. A highly maneuverable airplane, such as a fighter, has a capability to accelerate or slow down very quickly, and also to turn sharply.
Can you crush a skull with your thighs?
According to some references, it would take a minimum of 250kg of force to crush a skull. The Mountain is a very big man, and in the books he weighs 420 pounds – almost 200kg. Much of this would be in the muscle and bone of his legs and torso.
What fruit is comparable to a human skull?
So yeah, watermelons are about the same density as a human head..
What has the same strength as a human skull?
For good measure, I asked Mattei about the strength of the human skull compared to other materials we know – wood, steel, etc. Turns out the human skull can withstand 6.5 GPa of pressure, while oak holds up under 11, concrete 30, aluminum 69 and steel 200.
How dense is the human skull?
The average den- sity by site ranged from 1.615 g/cm3 to 1.922 g/cm3. The temporal bone was the most dense, with a grand mean of 1.868 g/cm3, and the zygoma was the least dense, with a grand mean of 1.679 g/cm3.
What is the density of a watermelon?
We substitute this new value of the f into equation (5) and obtain the density of watermelon as 0.959 or 0.96 g cm − 3 to two significant figures.
What is a Densuke watermelon?
Densuke is a Japanese fruit known for possibly being the world’s most expensive type of watermelon, reaching prices up to $6,000 at auctions for top quality produce. The watermelon is black in color, crisp, and hard, with a different level of sweetness than other watermelons. It also has very few seeds.
What is the density of an apple?
0.96 g/cm3
Does an apple sink or float?
Pumpkins and apples float in the water because they are less dense than the water – meaning they are buoyant. The fall fruits contain a lot of air (even pumpkins because they are mainly hollow inside despite their size).
How do you find the density of an apple?
Use a pin to hold the apple under the water. Record the volume of water in the graduated cylinder — this is the volume of the apple. Calculate the density of the apple (Density = Mass/Volume).
