Answer 14

=(Antarctic iceberg is 4.55 ⋅ 10^13)-(Rock of Gibraltar is 1.78 ⋅ 10^12)

=(45.5 ⋅ 10^12)-( 1.78 ⋅ 10^12)

=4.55 . 10^13

Answer 19

PART A
in 1 second -->3.9 * 10^33
in 1.55*10^7 seconds-->3.9 * 10^33*1.55*10^7
=6.04*10^40

Answer 20

And part B? Also after that can you please go over the answers? Like tell me each one in one comment?

Answer 21

PART B
it should 1.6 ⋅ 10^−3 mm

as the other options value will be much large in terms of a normal CD
