How to know that linear differential equation is time invariant or time variant?
If the coefficients of the linear differential equation are dependent on time, then it is time variant otherwise it is time invariant. E.g: 3 * dx/dt + x = 0 is time invariant 3t * dx/dt + x = 0 is time variant
How do you measure time without using time invariant properties of any object?
The simple answer is by using time variant properties.
Practical example for Time-invariant system?
System whose domain is not in time can be a time invariant system. Ex: taking photo to a fixed object. here domain is not in time so photo wont change with time
What are the systems classifications?
according to time domain 1)linear and non linear systems 2)stable and unstable systems 3)static and dynamic systems 4)causual and non casual systems 5)time variant and time invariant systems 6)invertable and non invariable systems
Why Laplace transform is used in analysis of control system why not Fourier?
it is used for linear time invariant systems
What happens to the invariant quantities in special relativity?
In special relativity, the invariant quantities, such as the speed of light and the spacetime interval, remain the same for all observers. This means that these quantities do not change regardless of the relative motion between observers. It is a fundamental principle of special relativity that these invariants are preserved in all inertial reference frames.
What is the term for the relationship between the speed of light and the measurements of the time and space?
interval, which is invariant regardless of frame of reference.
What is proper length?
Proper length in physics is the invariant measure of a distance between to separated events. It is considered as the ideal length in a space-time of space-like paths.
An element that decays to another element over a period of time is?
A property of that element. An unstable element. A radioactive element
What is meant by the Founding Fathers were men of their time?
What is meant by "the Founding Fathers were men of their time"
What is the time taken to insert an element after an element pointed by some pointer?
Constant time.
Can you give a sentence using the word element?
i have the element of time
