PLEASE HELP WILL MARK BRANLIEST Perform the following conversions. Show your set ups. a. 683 nanometer (nm) to angstrom (Å) b. 520 mi/h to m/sec c. 0.714 g/cm3 to lb/ft3 d. -164°C to °F

Explanation:

a. 1 nm = 10Å

683nm=683×10Å

=6830 Å

b. 1 mi/h=0.44704

520 mi/h=520×0.44704

=232.4608

c. 1 g/cm3=62.427961 lb/ft3

0.714 g/cm3=0.714×62.427961 lb/ft3

=44.573564

d. 1°C =9/5 +32 =33.8°F

-164°C = -164×9/5+32 = -263.2°F
