Which measurement of length is the smallest?
9 x 10–6 m
7 x 10–5 m
7 x 101 m
9 x 102 m

Answer : The correct option is .

Explanation :

Length : It is defined as the measurement of any object from end to end.

The length is measured in many terms like in Meter, Centimeter, Kilometer, etc.

The higher the negative power of 10, the lower will be the value.

And the higher the positive power of 10, the higher will be the value.

Therefore, the smallest value of length is .

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
