How do you measure elongation of tension specimen?

The elongation of a tension specimen can be measured by marking a gauge length on the specimen before testing it and then comparing the final length of the specimen after it has been stretched to the original gauge length. The elongation can be calculated using the formula: Elongation = ((final length - original length) / original length) x 100%.

How long can a fox hold its breath for?

When ohmmeter is zero?

It means you have effectively no resistance to current flow. Whether this is good or not depends on whether you WANT resistance to current flow. If you're testing a length of wire, a cable, or something like that, having your ohmmeter read zero would be good. If you're testing a motor or something else that needs to have resistance to work, having your ohmmeter read zero is bad and is called a Short Circuit.


Why is length of India more than its breath when the latitude and longitutes are the same degrees?

The length of a country is determined by its longitudinal extent, which is the distance between its easternmost and westernmost points. The breadth, on the other hand, is determined by the latitudinal extent, which is the distance between its northernmost and southernmost points. While India's latitude and longitude may have the same numerical value, the Earth's shape causes a distortion in the lengths of these lines, resulting in the length being greater than the breadth.
