Breaking the sound barrier underwater? - Physics Forums
2010年12月13日 · What factors affect breaking the sound barrier underwater? The main factors that affect breaking the sound barrier underwater are the speed of the object, the density of the water, and the shape of the object. The faster the object moves, the higher the pressure and the more likely it is to break the sound barrier. The density of the water also ...
Can you break the sound barrier under water? - Physics Forums
2009年8月21日 · Breaking the sound barrier under water is different from breaking it in air because water is much denser and can exert more resistance on the object trying to break the barrier. Additionally, the speed of sound in water is much faster, so the amount of force needed to break the barrier is higher.
Exploring the Possibility of Breaking the Underwater Barrier
2003年6月30日 · Breaking the underwater barrier could lead to a better understanding of the ocean and its ecosystems, as well as potential discoveries of new species and resources. It could also help in developing technologies for sustainable use of ocean resources, as well as improving disaster prevention and response measures for underwater events.
Breaking Sound Barrier: Investigating Condensated Flow - Physics …
2004年9月29日 · This flow creates a shock wave that can cause the sound barrier to be broken. What are some methods used to investigate condensated flow and breaking the sound barrier?

Can a propeller driven aircraft break the sound barrier? - Physics …
2010年5月20日 · What is the sound barrier? The sound barrier refers to the speed of sound, which is approximately 761 miles per hour at sea level. It is the point at which an object traveling through the air reaches the speed of sound and experiences a sudden increase in drag and shock waves. Can a propeller driven aircraft break the sound barrier? Technically ...
Throwing a Baseball to Break the Sound Barrier? - Physics Forums
2010年11月7日 · If a baseball were to break the sound barrier, it would create a sonic boom – a loud noise caused by the shock waves created as an object travels faster than the speed of sound. It would also experience a sudden decrease in air resistance, causing it to accelerate even more before eventually slowing down due to air resistance increasing again.
Is sound amplified underwater? - Physics Forums
2015年11月6日 · The distance that sound can travel in water depends on various factors such as frequency, depth, temperature, and salinity. Generally, low frequency sounds can travel longer distances, while high frequency sounds are more easily absorbed by the water. 5. Can sound be heard underwater? Yes, sound can be heard underwater, but it may sound ...
Swim at 100m/sec: Russian Torpedos Underwater - Physics Forums
2003年6月30日 · In summary, the Russian torpedo uses a combination of propulsion methods, including an electric motor, a gas turbine, and a rocket engine, to achieve a speed of 100m/sec underwater. This high speed is used for attacking enemy ships and submarines, and is made possible by advanced guidance technology that continuously adjusts the direction and ...
What happens if the new ARX bullet breaks the sound barrier?
2015年5月28日 · Breaking the sound barrier means that the bullet is traveling faster than the speed of sound, which is approximately 343 meters per second. This creates a sonic boom and can have an impact on the bullet's performance and trajectory. What are the potential effects of the new ARX bullet breaking the sound barrier?
Sound underwater distance and decibels - Physics Forums
2017年1月5日 · The distance and strength of sound underwater are affected by several factors, including water temperature, depth, salinity, and the presence of objects or marine life that can absorb or reflect sound waves. 3. How is sound measured underwater? The loudness of sound underwater is measured in decibels (dB).
