When a sound from a source is refacted away from the surface of the earth it gives an indication that?
the sound wave has traveled through layers of the atmosphere with different densities, causing it to bend away from the surface. This refraction phenomenon can occur due to variations in temperature, wind speed, and pressure at different altitudes in the atmosphere.
Does the ramp surface effect the speed of a car?
yes, of course different surface different amount of friction
How is the speed of a deep ocean current different from a surface current?
3
How is a surface current different from a deep water current?
Different pressure levels will vary speed and direction
Does a different surface affects the marble speed?
Yes, the smoothness of the surface can affect the speed of the marble. A smoother surface will result in less friction, allowing the marble to roll faster. Conversely, a rougher surface will create more resistance and slow the marble down.
What is the velocity of sound at moon surface?
The velocity of sound on the Moon's surface is about 1,092 meters per second, which is approximately 3.7 times slower than the speed of sound in air on Earth. This slower speed is due to the Moon's lack of atmosphere, which affects the transmission of sound waves.
Why is it important that a satellite be above Earths atmosphere?
Please remember that close to Earth's surface, a satellite must move at a speed of about 7900 meters/second. If it is inside the Earth's atmosphere, the force of friction will make the satellite lose energy. As a result, it will soon crash to the Earth's surface.
Why does spaceships catch on fire while coming back to earth?
It has a high speed as it begins re-entry, but the earths atmosphere slows it down as it approches the surface. The heat comes about due to the friction of the atmosphere on the shuttle as it slows.
Why does the space shuttle have high speed in the atmosphere?
The shuttle uses the atmosphere to slow itself down from orbital speed.
A Sound from a source is refracted away from the surface of the earth what does it mean?
When a sound wave travels through different layers of the atmosphere with varying temperatures, it can result in the sound being refracted away from the surface of the Earth. This happens because the speed of sound changes with temperature, causing the sound wave to bend away from the normal propagation path.
What makes light waves change speed as they travel from the sun to the Earth's surface?
Light has a single speed in a vacuum - which is almost 300,000 kilometers per second. Once light enters Earth's atmosphere, it will be slightly slower.
What survives impacting the earths surface?
Large objects like meteorites, asteroids, and comets have the potential to survive impacting the Earth's surface. Depending on their size, composition, and speed, these objects can withstand the heat and pressure of entering the Earth's atmosphere and make it to the surface relatively intact.
