  1. foot

  2. pound

  3. metre

  4. none of these

Show answer
Correct Option: A
Explanation:

Foot is the unit of length in the F.P.S. system.

Parsec is a unit of time.

physics measurements and experimentation measuring distance of celestial bodies unconventional units of measurements units of mass

  1. True

  2. False

Show answer
Correct Option: B
Explanation:

Parsec is a unit of distance used in astronomy. $1\ Parsec $$=3.086\times 10^{13}\ km$

Thus, the given statement will be false.

physics measurements and experimentation measuring distance of celestial bodies unconventional units of measurements units of mass

  1. 250

  2. 30,000

  3. 22.5

  4. 15,000

Show answer
Correct Option: B
Explanation:

The sun is located 30,000 Light-years away from the galactic centre.

$1$ kg = __________ pounds

physics measurements and experimentation measuring distance of celestial bodies unconventional units of measurements units of mass

  1. 5.121

  2. 1.856

  3. 2.203

  4. 0.547

Show answer
Correct Option: C
Explanation:

one kg is equal to $2.203$ pounds

$\Rightarrow 1$ kg  $=2.203$ pounds
Therefore option $C$ is correct

Which of the following is a NOT non-metric unit of mass ?

physics measurements and experimentation measuring distance of celestial bodies unconventional units of measurements units of mass

  1. tons

  2. pounds

  3. ounces

  4. kilograms

Show answer
Correct Option: D
Explanation:
Pounds,tons and ounces are non metric unit of mass
The basic metric unit of mass is kilogram
So kilogram is not non metric unit of mass
Therefore option $D$ is correct

One astronomical unit is the mean distance between the centre of the Earth and centre

of the_________ .

physics measurements and experimentation measuring distance of celestial bodies unconventional units of measurements units of mass

  1. Mars

  2. Moon

  3. Sun

  4. Jupiter

Show answer
Correct Option: C
Explanation:
One astronomical unit (AU) is defined as the mean distance between the centre of the Earth and the centre of The Sun.
$ \ AU = 1.5\times 10^{11} \ m$

One light year is used for measurement of large distances?

physics measurements and experimentation measuring distance of celestial bodies unconventional units of measurements units of mass

  1. True

  2. False

Show answer
Correct Option: A
Explanation:
One light year is defined as the distance travelled by light in one year in vacuum.
$1 \ light  \ year = 9.5\times 10^{15} \ m$
Since, one light year is very large value. Thus one light year is used for measurement of large distance.

Parallax method is used to measure small distances between molecules?

physics measurements and experimentation measuring distance of celestial bodies unconventional units of measurements units of mass

  1. True

  2. False

Show answer
Correct Option: B
Explanation:
Parallax method is used to measure very large distance, probably the diameter of the sun, moon and other planets etc.
Thus the given statement is false.
