One astronomical unit is the distance between the centre of the earth and _____________
- Centre of the Moon
- Centre of the Sun
- Centre of the Mars
Correct Answer

A. Centre of the Sun

Explanation

One astronomical unit is the distance between the center of the earth and the center of the Sun. This unit is used to measure distances within our solar system. The center of the Moon and the center of Mars are not used as reference points for measuring astronomical units.

Screw gauge is an instrument to measure the dimensions of very small objects upto _____
- 0.1 cm.
- 0.01 cm.
- 0.1 mm.
- 0.01 mm.
Correct Answer

A. 0.01 mm.

Explanation

A screw gauge is a highly precise instrument used to measure the dimensions of very small objects. It consists of a screw mechanism that allows for extremely accurate measurements. The answer of 0.01 mm indicates that the screw gauge can measure objects with a precision of one hundredth of a millimeter. This level of accuracy is necessary when dealing with very small objects, such as microchips or microscopic organisms, where even the smallest variations in dimension can have significant effects.

In a screw gauge zero of the head scale lies below the pitch scale axis, the zero error is ______
- Positive
- Negative
- Nil
Correct Answer

A. Positive

Explanation

The given question is asking about the zero error in a screw gauge where the zero of the head scale lies below the pitch scale axis. In this case, the zero error is positive. This means that the actual measurement will be greater than the reading obtained from the instrument.
