Equally.
I cannot say about "lenght", but distance is a measure of length so length affects distance. Speed is the rate of change of distance (over time) so length affects speed. Mass does not significantly affect speed or distance but, because they are affected by acceleration and acceleration is affected by mass (for a given force), then mass affects them. Also, mass affects space time and the presence or absence of mass changes the lines along which distances are measured and so distances and speed are affected.
It is decreased by half. If you decrease the width by half and leave the length alone, you get the same result.
It is 27 times the original.
the area also doubles
32 +82 =9+64=73 So the hypotenuse is of length square root of 73
The length of nails is affected by your mom.
Nothing. Resistivity is a physical characteristic of a material. It's not affected by its shape, etc.
NO
No, only weight is affected by gravity: attraction, force, acceleration.
The length of the planet's year would be affected.
What happens to the quick return ratio when the stroke length is reduced?
Equally.
The shorter the string - the faster the oscillation.
When you shorten the wave length, you increase the amplitude.
stays the same length
It increases 8-fold.
