That's the "parsec", equivalent to about 3.26 light years.

Where do comets get their speed?
Any object that comes from a large distance will acquire speed as it approaches the Sun, due to Earth's attraction. The speed from this mechanism alone will be about 42 kilometers per second, for an object at 1 AU from the Sun.
Does an object dropped from twice as high take twice the time to fall?
No. Objects falling on Earth in a vacuum fall at an increasing speed of 32 feet per second per second and the same object dropped from the higher level will be traveling faster during the second half of its fall, thereby it will take less than twice the time required to fall half the distance.
What nerve supplies the maxillary first and second premolars?
[object Object]
How do you calculate the velocity of a moving object?
The change in distance divided by change in time. So say it moved 10 meters in 5 seconds, it would be 2 meters per second.
What did newton call the force exerted by the second object on a second object?
The equal force in the opposite direction.
What affects the gravitational pull between two objects?
The mass of the first object; the mass of the second object; the distance between them.The mass of the first object; the mass of the second object; the distance between them.The mass of the first object; the mass of the second object; the distance between them.The mass of the first object; the mass of the second object; the distance between them.
What can be said about the distance that a freely falling object travels in one second?
With the information given, all that can be said is that the distance is greater than the distance the object traveled in the previous second.
When an object is traveling the same distance every second it has a?
constant speed
What are the factors that affect gravitation?
Mass of the first object, mass of the second object, distance between the objects.
What is a parsec a measure of?
a unit of distance used in astronomy, equal to about 3.26 light years (3.086 × 10^13 kilometers). One parsec corresponds to the distance at which the mean radius of the earth's orbit subtends an angle of one second of arc.
Suppose an object is in fall Each second the onject falls?
ANSWER: a larger distance than in the second before
What is the distance covered by an object in last one second of its motion?
i think it 1/6 of total distance......:D
An object is dropped and is in free fall The speed of the falling object and the distance it falls are measured every second Which of the following is correct?
The speed stays thesame but the distance stays the same.
An object is dropped from rest at a height of 128 m. Find the distance it falls during its final second in the air.?
If an object is dropped from rest at a height of 128 m, the distance it falls during its final second in the air is still 128 m.
Does a falling stone travel te same distance each second it falls?
No. Since the speed of a falling object keeps increasing, it falls through more distance in each second than it did in the second before.
What is the distance an object travels each second for objects falling under constant acceleration?
2.
What is uniform speed?
If an object covers equal distance in equal intervals of time, we can say that the object is moving with a uniform speed. E.g. consider an object moving along straight line. Let it travel 5 m in the first second, 5 m more in the next second, 5 m in the third second and 5 m in the fourth second. In this case, the object covers equal distance in equal intervals of time so we can say that the object is moving with a uniform speed.
