Question

10. Five energies are listed.
5 kJ 5 mJ 5 MJ 5 nJ
Starting with the smallest first, what is the order of increasing magnitude of these energies?
A 5 kJ → 5 mJ → 5 MJ → 5 nJ
B 5 nJ → 5 kJ → 5 MJ → 5 mJ
C 5 nJ → 5 mJ → 5 kJ → 5 MJ
D 5 mJ → 5 nJ → 5 kJ → 5 MJ

Answer 1

note: n<m<k<M in order of prefixes.
