Two boxes move at a right angle to each other on a frictionless surface, as shown in the figure below. The mass moving along the x-axis has a mass of 6.0 kg and a speed of 10 m/s. The mass moving along the y-axis has a mass of 4.0 kg and a speed of 20 m/s.  The directions of the two velocity vectors are indicated in the figure. The boxes collide and stick together after the collision. What is their common speed after the collision? 

Ice age sea level change:  Recall that sea level is where the top surface of the ocean meets the land.  It is affected by the height of the ocean and by the height of the land.  Either one can move up or down. a) What is one major reason why global sea level (eustatic sea level) changes between glacial and interglacial periods? b) Why do glaciers/ ice fields cause sea level to change by different amounts (tens to hundreds of meters) in some regions compared with others? bonus) what is a second major reason why global sea level changes between glacial and interglacial periods?

The size and shape of ocean basins change over time.   Imagine that ocean basin A currently covers a larger area than ocean basin B.  Using the concepts of diverging and converging plates, suggest two (2) possible histories that explain how/why ocean basin A covers a larger area than ocean basin B. Be sure that the words divergent (diverging) and/or convergent (converging) are used in each response. 1.  2. 

Open your list of running applications (your screen will be recorded, and this list will be reviewed) PC users: Press Ctrl + Shift + Esc to open Task Manager. Click “Name” to sort apps alphabetically (A -> Z). Mac users: Press Command (⌘) + Option + Esc to open Force Quit Applications. Chromebook users: Press Search + Esc to open Task Manager. Click “Task” column to sort apps alphabetically (A -> Z). Scroll through the list of running applications to confirm only necessary programs are open. Please move slowly through the entire list so everything is clearly visible. Skipping or failing to show all applications will flagged. 

Seafloor mapping:  The two modern methods of mapping the seafloor (water depth) are echo sounding (sonar) satellite altimetry 1. Explain how echo sounding works (2-4 sentences).  Be sure to include what is measured how these measurements are converted to water depth. 2. Briefly state one advantage of using satellite altimetry over echo sounding.
