Q96.
In a virtual wind tunnel, how are air movements simulated?

a.

By physically releasing bubbles into the chamber

b.

By attaching small pieces of ribbon to the aircraft surface

c.

By calculating using the equations of fluid dynamics

d.

By using polarized light to expose airflows

Discuss
Answer: (c).By calculating using the equations of fluid dynamics Explanation:In a virtual wind tunnel, air movements are simulated using the equations of fluid dynamics to calculate patterns of air movement and pressure.
Q97.

a.

Ability to save money on model making

b.

More accurate representation of aircraft

c.

Capability to measure turbulence directly

d.

Closer inspection of simulated aircraft details

Discuss
Answer: (d).Closer inspection of simulated aircraft details Explanation:In a virtual wind tunnel, engineers can get as close as they like to the simulated aircraft to investigate details, which is not easily achievable in a real wind tunnel without disrupting airflow.
Q98.
In the context of relief maps, what does the height represent?

a.

Terrain features

b.

Average annual rainfall

c.

Distance from the viewing point

d.

Abstract data points

Discuss
Answer: (b).Average annual rainfall Explanation:In relief maps, the height represents average annual rainfall at each point, rather than the height of the terrain.
Q99.
What are the challenges associated with representing data using two spatial dimensions and one data dimension?

a.

Choosing a suitable viewing point

b.

Avoiding the use of 3D patterns

c.

Keeping foreground structures small

d.

Making data patterns less abstract

Discuss
Answer: (a).Choosing a suitable viewing point Explanation:Representing data using two spatial dimensions and one data dimension can be challenging because it's difficult to choose a suitable viewing point that doesn't hide important features due to foreground structures.
Q100.
How can animation enhance the visualization of scientific and technical data?

a.

By presenting static snapshots of the data

b.

By introducing complexity and confusion

c.

By encouraging passive data consumption

d.

By promoting user engagement and discovery

Discuss
Answer: (d).By promoting user engagement and discovery Explanation:Animation in data visualization can promote user engagement and discovery by allowing users to interactively explore and understand complex information.
