Answer 1

Explanation:

A)

$1 \: nano \: meter \: = {10}^{ - 9} m$

$93 \: nano \: meter \: = 93 \times {10}^{ - 9} m$

93 nm = 0.000000093m

B)

$1 \: milli \: gram \: = {10}^{ - 3}g$

$1 \: kg \: = {10}^{3} g$

$1g = {10}^{ - 3} kg$

$1 \: mg \: = {10}^{ - 3} \times {10}^{ - 3} kg$

$1mg = {10}^{ - 6} kg$

$0.8mg = 0.8 \times {10}^{ - 6} kg$

$0.8mg \: = 8 \times {10}^{ - 7} kg$

C)

1 MJ = 10⁶ J

120 MJ = 120 × 10⁶ J =12×10⁷J

D)

$1us = {10}^{ - 6} sec$

$59 \: u \: sec \: = 59 \times {10}^{ - 6} sec$

59 u sec = 0.000059 sec
