There are formulae, but it is much easier to simply use a "voltage drop calculator" (many interactive ones can be found online), plug in your values and increase your conductor size until the calculated voltage drop over the required distance, at 1.25 times the required load (80 percent design factor), does not exceed 5 percent (the allowed voltage drop in USA and Canadian electrical codes, other countries vary).
For instance, your example could use 14 AWG, giving you a 4.8 percent drop, or 12 AWG for a 3 percent drop (assuming copper). If you were to use aluminum, you would need the larger conductor.
To calculate the gauge of wire needed for a specific distance and amperage, you can use the voltage drop formula. For a 500 ft run at 1.5 amps and 120V, you would need a minimum of 16 gauge wire to keep the voltage drop below 3% which is typically acceptable for most applications. However, for longer distances or higher amperage, you may need to use a thicker wire gauge to minimize voltage drop.

To calculate the area of a trapezoid, you can use the formula: Area = 0.5 * (sum of bases) * height. Simply add the lengths of the two parallel sides (bases) of the trapezoid, multiply the sum by the height, and then divide by 2 to find the area.
The factors that affect the resistance of a conductor are the material it is made of, the length of the conductor, the cross-sectional area of the conductor, and the temperature of the conductor. Materials with high resistivity, longer lengths, smaller cross-sectional areas, and higher temperatures will have higher resistance.
The formula for the area of a trapezoid is A = (a + b) * h / 2, where a and b are the lengths of the two parallel sides, and h is the height of the trapezoid.
The formula for the area of a trapezoid is A = (1/2) * (a + b) * h, where 'a' and 'b' are the lengths of the parallel sides and 'h' is the height of the trapezoid.
That would be "perimeter". The perimeter is the distance around a figure, and it is calculated by adding the lengths of the different sides. For example, for a triangle, add the lengths of the three sides.

To find an object's weight using a lever, you can use the principle of torque. By measuring the lengths of the lever arms on either side of the fulcrum, along with the distance from the object to the fulcrum, you can calculate the weight of the object. This is typically done using the formula: weight = force x distance.
The answer depends on what information you have. If you know the lengths of the two parallel sides (a and b) as well as the vertical distance between them (h), then Area = (a + B)*h/2 square units. Obviously, a different formula will be required if you have information about other aspects of the trapezium.
I assume those would be the lengths of the three sides. If you know the lengths of the three sides of a triangle, you can use Heron's formula to calculate the area. For more details, read the Wikipedia article on "Heron's formula".
yes sure by using the formula v=l*b*h
There is no standard formula. The answer will depend on the compound shape and also on which of the lengths (or angles) are known.
there are so many lengths in distance .The SI label for distance is meter.
Once you know the coordinates, you can use the distance formula to find the lengths of the sides, then using that, you can find the area.
There are many formulas for perimeter depending on what shape you are trying to find the perimeter of. The perimeter is the distance around a shape, so one formula to find perimeter is simply adding all the side lengths together.
You'd have to know some relationship, formula, equation etc. among the angles and the lengths. There would be many relationships to choose from if the items you mention are the parts of a triangle, but if they are, you've kept it a secret.
It depends on what information you do have about the triangle. There are different equations depending on whether you know the lengths of three sides, the lengths of two sides and the measure of the included angle, the length of one side and the perpendicular distance to the other vertex (base and height).
