Suppose that you find the volume of all the oceans to be 1.4×109km3 in a reference book. To find the mass, you can use the density of water, also found in this reference book, but first you must convert the volume to cubic meters. What is this volume in cubic meters?

,

Explanation:

The volume of all oceans is:

Ocean water has a density of , the mass of all oceans is:

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

the answer is b, have negligible mass
