Why do you use fins and cone for a bottle rocket?
You use fins and a nose cone on a bottle rocket because the cone reduces the drag on the rocket, and the fins help stabilize the rocket.
What does the term drag mean in flight?
Drag is one of the four forces applicable to a flying aircraft: thrust, drag, lift and weight. Drag is the amount of resistance to forward motion caused by a solid body moving through a fluid (air is considered a fluid for the purpose of aerodynamics). The easiest way to feel the effect of drag is to stick one's arm out a car window while it's moving. First do it palm-down (horizontal), and then palm-forward (vertical). The force, known as "drag", pushing the arm backward increases substantially when the palm is vertical. That force is the same effect that an aircraft in flight experiences due to the frontal area of its airframe forcing its way through the air. The science of aerodynamics seeks to minimize the drag through streamlining and other design factors, since drag wastes fuel, but it is physically impossible to elimnate it.
How do you make a block movable using javascript?
search google for 'drag and drop script' OR go and download script.aculo.us, and implement the great drag and drop scripts they have.
What was the big hog drag line?
The big hog drag line was once the world's largest shovel. It was used for strip mining of coal in Drakesboro, KY.
Is copy and paste same as drag and drop?
No. Drag and drop is when you drag a file then drop it into the destination folder. You have moved a file from one place to another. Copy and paste is when you copy a file then paste it into a different location. The original file still remains where it was, but there is how a copy of it elsewhere as well.
Name the element of art which is a moving dot that has length and width?
Line. If you think of the tip of a pencil as the dot, and you drag it across paper, you get a line that can vary in both length and width.
Why do they close airplanes gear when it takeover?
the gear creates a lot of drag so raising it reduces that drag
How does swept back wing reduce induced drag?
A swept back wing reduces induced drag by allowing the wing to better distribute lift across its span. This helps to minimize the formation of turbulent wingtip vortices which contribute to induced drag. Additionally, the sweep angle reduces the effective angle of attack at the wingtips, which further reduces induced drag.
How does drag affect a paper airplane?
Drag effects paper airplane just as it affects anything else that moves. It is either parasitic or induced on paper airplanes. Drag may reduce a paper airplanes speed and/or range.
What is the importance of lift to drag ratio?
The lift to drag ratio is important because it provides a measure of the efficiency of an aircraft or wing in producing lift while minimizing drag. A high lift to drag ratio indicates that the aircraft can generate sufficient lift with minimal drag, which is crucial for achieving greater fuel efficiency and longer flight range. Pilots and engineers use this ratio to optimize the performance of an aircraft by finding the right balance between lift and drag.
What does drag affect paper airplanes'?
Drag affects everything that flies.
Why is maximizing the ratio of lift to drag forces desirable?
Maximizing the lift-to-drag ratio is desirable because it allows an aircraft to generate more lift for a given amount of drag, resulting in improved fuel efficiency and range. A higher lift-to-drag ratio also means the aircraft can fly at higher altitudes and speeds, which can be beneficial for performance and overall aircraft capabilities.
What does drag mean?
Drag coefficient can be defined as the ratio of the drag on a body moving through air to the prioduct of the velocity and the surface area of the body.
What is increase column?
You could mean increase the column width, which just makes it wider. You can drag it out or set a fixed width.
How does flying at high attitudes helps large commercial airplane reduces drag?
at that alltitude there is less air so there is less drag from ther air.
How does streamlining reduce drag?
Streamlining reduces drag by optimizing the shape of an object to minimize resistance against air or water flow. By smoothing out surfaces and reducing turbulent areas, streamline shapes decrease the drag force acting on the object as it moves through a fluid. This reduction in drag helps to improve the object's aerodynamic or hydrodynamic efficiency, ultimately leading to lower energy consumption and improved performance.
How do you adjust the column width and or row height of many cells at once in Excel 2010?
Select more that one row or column and then set the width or height in the normal manner. It will affect every row or column that is selected. You can drag out the height or width of the first selected row or column to do it.Select more that one row or column and then set the width or height in the normal manner.
