The look back time of an object is determined by how long it takes the light from that object, usually a star or galaxy, to reach an observer here on earth.

What is the concept of look back time and how does it relate to our understanding of the universe's history?

The concept of look back time refers to the amount of time it takes for light from distant objects in the universe to reach us on Earth. By observing light from these objects, we are essentially looking back in time to see how they appeared in the past. This helps us understand the history of the universe by studying the evolution of galaxies, stars, and other celestial bodies over billions of years.


What is the amount of time it takes for an object to spin on its axis once is called?

anu way the answer is PERIOD OF ROTATION! hope i helped.


Why does the heaviest object have a larger mass than the lightest object?

The moon has less gravity Peggy says: Objects weigh more on the Earth than on the moon because the Earth has a greater mass. The mass of an object determines how much gravity it exerts. The Earth exerts six times the gravity of the moon. A 180 pound person on Earth would only weigh 30 pounds on the moon!


What is a system for stating the precise location of a object in space and time?

A system for stating the precise location of an object in space and time is known as the coordinate system. It uses coordinates to represent the position of the object within a specific reference frame. Common examples include the Cartesian coordinate system and the geographical coordinate system.


What is the difference between orbital period aNd synodic period?

The orbital period is the time it takes for an object to complete one orbit around another object, like a planet around a star. The synodic period is the time it takes for a given object to return to the same position in the sky relative to the Sun as seen from Earth, for example the time between two consecutive similar configurations of a planet as observed from Earth.

What determines an object's speed?

An object's speed is determined by the distance it travels in a given amount of time. It is calculated by dividing the distance traveled by the time taken to cover that distance. Speed can be affected by factors such as the object's mass, the force applied to it, and any resistance it encounters.


How can you look at a graph determines when an object is moving faster?

You can determine when an object is moving faster by looking at the steeper slopes on the graph. Steeper slopes represent greater changes in speed over time, indicating faster motion. Additionally, peaks in the graph may represent moments of maximum speed.


How can you tell if an object is moving if its to slow to see?

Look at it now, go away, come back some time later, and see if it's in a different place.


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.


Can you go back in time to look at Pangaea?

Does a jellyfish have tentacles?

Yes, they do. Depending on what kind of jellyfish determines what they look like. Often time, the tentacles do the stinging.


What is linear acceleration and how does it relate to the motion of an object?

Linear acceleration is the rate at which an object's velocity changes over time in a straight line. It is a measure of how quickly an object is speeding up or slowing down. Linear acceleration is directly related to the motion of an object because it determines how fast the object is moving and in what direction.


When do you see objects?

You see an object every time ever second every minute your eyes are open if u look to the left their an object if you look to the right there is an object as well objects are different size and shape!

What does the graph look like if the object stoping moving?

If an object stops moving, the position-time graph will show a horizontal line at the position where the object stops. This indicates that the object is at rest at that specific position, with no change in its position over time.
