4. How is nanometre related to Angstrom ?

5.Name the three convenient units used to measure length ranging from very short to very long value.

Answer 1

Answer:

1.)  The standard meter is the length of the path traveled by light in a vacuum during a time interval of. 1/299792458 of a second.

2.)   KILOMETRE and MILE are the two units bigger than metre.

1 Km= 1000m

1 Mile= 1609.34m

3.) Millimeter and centimeter are smaller than meter.

1 meter = 1000 Milli meter.

1 meter = 100 centimeter.

4.)  The nanometre and the angstrom, both are units of the length measurement.

1 nanometre = 10 angstroms

5.)  Three convenient unit used to measure length ranging from very short to large are - centimeter (cm) , metre (m) , and kilometer (km)

Meter is S.I. unit .

1m = 100cm

1m=1/1000km.
