What are coiled tunnels filled with fluid that vibrate in response to sound?

The structures you are referring to are the cochlea in the inner ear. These coiled tunnels are filled with fluid that vibrates in response to sound waves, which in turn trigger the sensory cells responsible for hearing.


What is the purpose of a wind tunnel?

A wind tunnel is used to simulate air flow over a model of an airplane or a wing section so it can be studied. The model can be instrumented to measure the lift and drag and other parameters for study. The wind tunnel can produce air flow at the desired speed and condition. Engineers may use a wind tunnel to study and design a wing shape. The Wright Brothers developed the first wind tunnel to design the shape of the wing for their airplane. Wind tunnels can be used to study interference between parts of the aircraft or between an airplane and a bomb as it drops away. There are different types of wind tunnels: low speed wind tunnels, supersonic wind tunnels and hyper-sonic wind tunnels.


Why was the LHC -Large Hadron Collider- built under the ground?

The Large Hadron Collider (LHC) was built underground to provide shielding from cosmic rays and other background radiation that could interfere with its sensitive experiments. Placing it underground also helps to enhance the stability of the particle beams circulating in the collider's tunnels.


Can a tornado be created in a lab environment?

No, not a real tornado. Tornadoes can be simulated on supercomputers, and vortices can be created in the lab. The latter example does provide insights into vortex mechanics, but their applications in processes specifically relating to tornadoes are limited.


As you are driving along you come to a road tunnel you cannot see daylight at the other end why?

Tunnels are typically constructed to create a direct passage through an obstacle such as a mountain or body of water. Therefore, due to the tunnel's design and curvature, it may not be possible to see daylight at the other end when you enter it. This is a normal feature of tunnels and is designed for safe passage through the obstacle.

How were lanterns used in the past from mining towns?

In mining towns, lanterns were used by miners to light their way underground since there was typically no natural light. The lanterns were either carried by hand or attached to their helmets, providing a portable source of light to enhance visibility in dark, cramped mining tunnels. These lanterns were often fueled by oil or candles and played a crucial role in maintaining safety and efficiency in the mining operations.

Why build the Leighton battery tunnels in Perth?

The Leighton battery tunnels in Perth were constructed to enhance the city's infrastructure, particularly in terms of energy storage and management. These tunnels serve as a vital component of a more resilient and sustainable energy system, allowing for the storage of renewable energy and helping to stabilize the grid. By integrating large-scale battery storage, the tunnels also support the transition to cleaner energy sources, ultimately contributing to reduced greenhouse gas emissions and improved energy security for the region.


What do earthworm tunnels provide passageways for?

air, water, and plant roots.


What tunnels are in downtown Fort Worth tx?

Downtown Fort Worth features a network of pedestrian tunnels known as the Fort Worth Tunnels, which connect various buildings, parking garages, and amenities. These tunnels provide a convenient way for pedestrians to navigate the area, especially during inclement weather. They are part of the city's effort to enhance walkability and urban connectivity. Additionally, the tunnels house art installations and provide access to shops and restaurants, enriching the downtown experience.


Which play tunnels provide some protection against scrapes and burns?

The play tunnels that provide the most protection are the ones that come with extra padding sewn in around the steel springs. A good website to get one from is creative play for less.


Why are polytunnels more useful than regular tunnels?

This is made from a special material(polyethylene). This is better than regular tunnels because it is possible to change the temperature, humidity and the ventilation. Also poly tunnels can provide a higher temperature then a normal tunnel.

What are the best ways to create an enriching environment for small pets using small pet tunnels?

To create an enriching environment for small pets using small pet tunnels, provide a variety of tunnels with different shapes and sizes to encourage exploration and exercise. Place tunnels in different areas of the pet's living space to create a stimulating environment. Additionally, incorporate treats and toys inside the tunnels to encourage play and mental stimulation. Regularly clean and rotate the tunnels to keep the environment fresh and engaging for your small pet.
