14.90. Set Up: so the sphere with twice the mass has twice the volume, For a sphere, and Solve: so and 14.91. Set Up: The radius of the earth is Since an ocean depth of 100 m is much less than the radius of the earth, we can calculate the volume of the water to this depth as the surface area of the oceans times 100 m. The total surface area of the earth is The density of seawater is (Table 13.1). Solve: The surface area of the oceans is The total rate of solar energy incident on the oceans is 12 hours per day for 30 days is so the total solar energy input to the oceans in one month is The volume of the seawater absorbing this energy is The mass of this water is so Reflect: A temperature rise of is significant. The solar energy input is a very large number, but so is the total mass of the top 100 m of seawater in the oceans. 3.4 C° D T 5 Q mc 5 4.65 3 10 23 J 1 3.51 3 10 19 kg 21 3890 J

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
