To calculate the distance of an object based on echo timing, measure the time it takes for a sound wave to travel to the object and back. Divide this time by 2 to get the one-way travel time. Then multiply the one-way travel time by the speed of sound in the medium the sound is traveling through (approx. 343 m/s in air at room temperature) to find the distance to the object.

What is the formula to determine how far away is an object whose echo takes 9 seconds to return?
The formula to determine distance based on echo time is: Distance = (echo time * Speed of sound in air) / 2. Since sound travels at approximately 343 meters per second in air, if the echo takes 9 seconds to return, the distance from the object would be approximately 1543.5 meters away.
What does the image of an object look like for a concave mirror when the object is far away?
When the object is far away from a concave mirror, the image formed is real, inverted, and highly magnified. This image is formed at the focal point of the mirror.
What happens when you hold an object far away from a concave mirror?
When you hold an object far away from a concave mirror, the mirror will produce a real image that is inverted and smaller than the object. The image will be formed at the mirror's focal point.
What location does the image approach as the object gets arbitrarily far away from the mirror?
Half the radius of the mirror, also known as the focal point.
What type of image is formed when you use a concave mirror far away?
When a concave mirror is far away, it forms a real and inverted image. The image will be smaller than the object and located at the focal point of the mirror on the same side as the object.

What can bats tell about an insect from its echo?
they can tell where an insect is and how far away it is
How does echo form?
Sound waves are created when an object vibrates, sending out energy in the form of waves. When these waves hit a surface, they bounce back towards the source, creating an echo. The time it takes for the sound to travel to the surface and back determines how far away the surface is and the strength of the echo.
How far away is an object whose echo takes 9 seconds to return?
About 1548 metres, which is roughly one US mile. But it varies with temperature, humidity, and height above sea level.
How does an artist indicate how close or far away an object is?
An artist indicates how far or close or how far away an object is by estimating it. It all depends on the artist himself as well as their peripheral visions.
How do bats use their ears to catch insect?
------------------------------------------------------- Bats use a type of "sonar" to locate objects even in the dark (echo-location). A bat makes a high-pitched noise that bounces off objects nearby and the bat hears the echo. By timing how long it takes for the bat to hear the echo, it can calculate how far away it is. When it comes to a flying insect, the bat listens to the echo of it's noises and is able to locate where an insect is. Then it can fly to the insect and catch it - even if it is pitch dark. They use echo location. It is tiny beeps, too high pitched for our ears, and dogs ears too! The bats let out the tiny beeps, and the echoes tell them where bugs are.
How far away does an object have to be for a wolf to smell it?
Wolves have been known to smell objects as far away as 1.6 km. An object does not have to be far away for a wolf to smell it, though - they can smell something right next to their nose.
Object used to hear sounds far away?
ultrasonic
What are instrument used to see object far away?
telescope
What does the image of an object look like for a concave mirror when the object is far away?
When the object is far away from a concave mirror, the image formed is real, inverted, and highly magnified. This image is formed at the focal point of the mirror.

When you hold an object far away from a concave mirror, the mirror will produce a real image that is inverted and smaller than the object. The image will be formed at the mirror's focal point.
What does the phrase 'A hop skip and jump away' mean?
It means that the object is close or not too far away.
