Can a moving object be selected as a reference object?
Any moving object can be redefined as a frame of reference at rest, from which all other moving frames can be measured. That's a fundamental precept of Relativity. It's motion is defined only in relation to some other object from which the motion is measured, so reselection as the rest frame is necessary, but once established as a rest frame, it is (for the purpose of measurement) no longer considered to be in motion. Since everything is moving in relation to everything else, any frame can be selected as the frame of reference at rest, with all other motion measured relative to it.
What is an intertial frame of reference?
Assuming you mean "inertial" frame of reference... it is any point of observation from which other objects appear to be still or in motion relative to you. For example... On an airplane flying at 35,000 feet. All the other passengers appear to you to be sitting in their seats or walking down the aisle at a leisurely pace... If you tossed a ball in the air, it would appear to go straight up and fall back into your hand... To someone on the ground, you and all your fellow passengers seem to be hurtling thru the sky at 500 mph. And the path the ball follows is not straight up or down. You and your fellow passengers share the same inertial frame of reference. In a similar sense, the earth under your feet appears to be still and all the objects seem to move or not move in relation to the still earth. In fact the earth is spinning... beyond that it is revolving around the sun, beyond that the entire solar system is moving in a galaxy that is, itself spinning, and the entire galaxy is also moving thru a universe that is expanding... Each of these are other inertial frames of reference. Einstein's theory of relativity states that none of these frames of reference is preferred... and that all observations, including those relating to time, dimension and speed, are entirely relative to one's inertial frame of reference. Thus different observers in different frames of reference perceive things differently. because even time varies with frame of reference, this renders such concepts as simultaneity specious. If time itself passes at different rates for different observers, then no two events can actually be said to happen at the same time.
A frame shift mutation occurs any time a gene mutation results in the insertion or deletion of a number of nucleotides that is not a multiple of three?

How to calculate Relative retention time?
Divide the retention time of the peak of ineterest (ex. 14.8 min.) by the retention time of the main peak (ex. 15.9 min.) 14.8/15.9 = 0.93 Therefore your RRT is 0.93 Remember, any peak with an RRT <1 elutes before the main peak, and any peak with an RRT >1 elutes after the main peak!

What is 69 o'clock in todays time?
There is no such time as 69 O'clock. The clock only goes to 12:00 (24:00).
What is speed of light in a car?
299,792,458 m/s - the same as any other time. Your frame of reference does not change the speed of light.
In a two-car system, which of the following are the same in any inertial reference frame?
In a two-car system, the relative velocity between the two cars is the same in any inertial reference frame.
What does the theory of special relativity say about the equivalence of different frames of reference?
It says that the speed of light in a vacuum measured in any inertial frame of reference is equivalent to the speed of light in a vacuum measured in any other inertial frame of reference.
What is movement in relation to a frame of reference called?
Relative motion is movement in relation to a frame of reference.
If zero mass particle have a speed c in one reference frame Can they be found at rest in other frame?
"c" is usually used, in this context, for the speed of light. If such a particle has the speed of light in one frame of reference, then, strange as it may seem, it will have the speed of light in ANY frame of reference.
What is the difference between an inertial and non-inertial frame of reference?
In an inertial frame of reference, objects move at a constant velocity or remain at rest without any external forces acting on them. In a non-inertial frame of reference, objects may appear to accelerate or experience fictitious forces due to the frame itself accelerating or rotating.
What is location of an observer of motion?
The location of an observer of motion is typically described in terms of a reference frame. This frame can be stationary or in motion itself, and serves as a point of reference to describe the position and movement of objects. Observers can be located at any point within this reference frame to study the motion of other objects relative to their own position.
Is absolute motion possible?
Absolute motion is motion relative to a presumed absolute reference frame. Special Relativity posits that the laws of nature are perfectly symmetrical with respect to any inertial reference frame. This implies that there is no absolute reference frame, and that absolute motion is a useless concept.
Difference between inertial frame of reference and non-inertial frame of reference?
An inertial frame of reference (FOR) is a non-accelerating FOR , for example if a person is observing a moving car while at rest or while moving at constant velocity, he is in an inertial FOR. A non-inertial frame of reference is an accelerating FOR for example a rotating FOR. ( Rotation requires centripetal force and centripetal acceleration so any rotating object always requires a centripetal acceleration to rotate.)
Where is the fixed point in the universe?
There do not appear to be ANY "fixed points" in the Universe. Everything is in motion, and there is no "preferred" frame of reference.
Can a moving object be selected as a reference object?
Any moving object can be redefined as a frame of reference at rest, from which all other moving frames can be measured. That's a fundamental precept of Relativity. It's motion is defined only in relation to some other object from which the motion is measured, so reselection as the rest frame is necessary, but once established as a rest frame, it is (for the purpose of measurement) no longer considered to be in motion. Since everything is moving in relation to everything else, any frame can be selected as the frame of reference at rest, with all other motion measured relative to it.
What do you mean by rest in physics?
Rest in physics refers to an object not changing its position with respect to a frame of reference. An object at rest has zero velocity and does not experience any changes in its position over time. This is often used as a reference point to analyze motion and interactions with other objects.
