An object moving in a frictionless envirnment has not impulse, but in all other moving objects have impulse. Impulse is defined as a change in momentum and therefore if the object is slowing due to friction it is has impulse.

How you explain the closer the light source to the object the larger the shadow?
By projecting imaginary lines from the light source to the object, you can explain this geometrically. The closer the light source, the wider the angle formed between the lines, and the wider the angle, the longer the line opposite will be.
What demonstrates that light travels in straight lines?
Can you see an object around the corner of a building
Where would you find the center of gravity on a plastic ruler?
Draw two lines from each corner. Where the two lines cross that is the centre of gravity PN This does not work for every object
How do you work out the volume of an irregular object?
by submerging it into a glass of water that has measurement lines and taking the difference between the original amount of water and the water with the object in it.You would use water displacement to find the volume of an irregular object.
What are raman frequencies?
i guess its the freq diff bet'n "rayleigh line" and "raman lines" ... but can anyone explain what the terms in quotes mean............?
How do astronomers determine the speed at which a galaxy is moving?
By examining its spectrum, and identifying absorption lines in it. Lines are shifted toward shorter wavelength if the object is moving towards us. They're shifted toward longer wavelength if the object is moving away from us.
When comparing two different lines on a position vs time graph how can you tell which object is moving faster?
The line which has greater slope stands for the fast moving object
How you explain the closer the light source to the object the larger the shadow?
By projecting imaginary lines from the light source to the object, you can explain this geometrically. The closer the light source, the wider the angle formed between the lines, and the wider the angle, the longer the line opposite will be.
What direction will spectral lines move if an object is moving towards you?
They will be blueshifted, that is their wavelengths will be shortened and their frequencies increased.
What are object lines?
Object lines are dark, thick lines used to define an object.
Distance between ehv lines?
The distance between high voltage lines is governed by either a switching impulse voltage or lightning impulse voltage. The distance between lines, or lines and tower must have a high enough dielectric strength to avoid flashover at these voltage. Air can withstand a voltage of 3kv/mm.
What is the definition of instrumentation impulse line?
The impulse line is the piping or tubing used to connect the transmitter to the process. To ensure correct readings, it is essential that impulse lines be installed correctly for the type of fluid that you are measuring. Consult your transmitter installation manual.
What are musical lines similar and dissimilar?

What are object lines used to identify?
Different thickness of lines denotes different things. Object lines are a specifice thickness (in relation to other lines on the same drawing) to visually identify 'objects'. Dimension lines are usually thinner, so as not to get confused with the lines that identify the object in question.
Why negative impulse is applied during Impulse voltage test?
The lightning phenomena is occurred on transmission lines or sub-stations due to which a negative wave is generated hence definitely destroy the power apparatus. So for impulse voltage testing of any power apparatus one must produce a negative impulse.
Why are macduffs lines 5-9 ironic?

How many lines of a symmetry does a rhombus has?
FOUR
