How does the resistance of a wire vary with its lenght?
If the wire's cross-section area is constant, then its resistance per unit length is constant, and the total resistance should be directly proportional to the length of a wire segment.
Which has greater resistance a thick wire or a thin wire of the same lenght?
The thin wire has more resistance to the flow of electric current than the thick wire. If you connect the wires to a battery the battery will supply electrical pressure (voltage) and the wires serve similar to pipes that conduct water under pressure. A small pipe exhibits more resistance to the flow of water and a thin wire exhibits more resistance to the flow of electrons. However, as you point out different wire materials exhibit different resistances for equal sizes (silver conducts better than copper, etc.).
How is mechanical advantage calculated for levers?
lenght of the effort arm divided by lenght of the load arm
What is the proper definition of frequency?
frequence is a wave lenght

Is a chord always equal to the lenght of the diameter?
No but the diameter is the largest chord in a circle.
If a diameter of a circle is 25 cm what is the lenght of a radius?
Diameter = 2*Radius. You should now be able to deal with this and similar questions.

What in the cable limits signal degradation?
A: As cable lenght increases the impedance changes with frequency especially at half wave lenght where at some frequency the impedance can be zero. The impedance is a function of capacitance inductance and resistance in the cable
How do you find diameter when you have length and width?
c=diameter a=lenght b=width c=sqrt(a^2 + b^2) ---- or in words, the diameter equals the square root of length squared plus width squares, that's the Pythagorean Theorem.
Why does a 3 pin plug have big ground pin?
Resistance =pl/a where a is "area". And area is directly propotional to lenght and thickness. so if the area is greater mean resistance is less. and resistance is inversly proptional to current. so it will act as low resistance path for neutral current.
How big is a plank length?
Planck lenght is equal to 1.616252×10−35 meters. 1020 times smaller than the diameter of a proton.
When saying calculating inch dia of pipe is number of welded joints x pipe size that refers to lenght of pipe or diameter of pipe?
Pipe size refers to the diameter of the pipe (in inch).
What is the radius of a circle?
The radius of the circle is the length between the middle of the circle and any of the sides. It is also half the lenght of the diameter.
