Screw gauge works under the principle of
The screw
The vernier caliper
Newton's law
Pascal's law
1 light light year is equal to
9.467 x 1015 m
9.467x1015 cm
9.467 x 1015 Km
9.467 x 1015 mm
In a Screw gauge, the head of the sleeve is divided into small divisions called
Head scale
Pitch scale
Safety device
Hallow cylindrical tube
The other name of screw gauge is
Rheometer
Micrometer
Nanometer
Decameter
In a Screw Gauge, the distance between two threads is called
Pitch of the screw
Least count
Zero error
Head scale reading
If the zero of the head scale in a screw gauge lies above the pitch scale axis, the zero error is
Positive
Negative
Zero
Can not be predicted
In a Screw Gauge the hallow cylindrical tube is graduated in millimeter called
U shaped frame
The mean distance of the centre of the sun from the centre of the earth is called
Light gear
Kilometer
Astronomical distance
Altimeter
Which of the following are / is the zero error/errors of a screw gauge?
No zero error
Positive zero error
Negative zero error
All the above
The distance travelled by light in one year in vacuum is called
Light year
