What is the maximum speed an object can reach in free fall?
That would be the escape velocity of Earth, about 11.2 km/sec. I am assuming that the object falls from far, far away, and that air resistance is negligible.That would be the escape velocity of Earth, about 11.2 km/sec.

An echo is heard from a building 6 s after you blow the cars horn so how far away is the building?
About 6,000 feet.
Describe the attitude and approximate size of the image when an object is very close to and far from a convex lens?
When the object is close it is big and upright when far away it is small and upright also
Why the far objects seems to move with us?
When objects are far away, the distance of the object is much greater than the distance that you are moving. Hence, there is little change in the relative position of you and the object.
How echoes are used in sonar?
Knowing how fast sound travels through water, the time taken for a noise to travel to a target (e.g. a shoal of fish or the sea bottom) and back gives an indication as to how far away the target is. The speed of sound in water is approximately 1500 m/s, so if an echo returns after 2 seconds then the reflecting object is 1500 m away.
What can bats tell about an insect from its echo?
they can tell where an insect is and how far away it is
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 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 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 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.
What are instrument used to see object far away?
telescope
Object used to hear sounds far away?
ultrasonic
When an object is too far away to be seen in a telescope what should be done with the object lens?
increased

What does the phrase 'A hop skip and jump away' mean?
It means that the object is close or not too far away.
How do you measure the height of an object too far away to measure the distance to the object?
Use trignometry
