Three forces are exerted on an object placed on a slope in the figure. the forces are measured in newtons (n). 1. assuming that forces are vectors, what is the component of the net force f⃗ net=f⃗ 1+f⃗ 2+f⃗ 3 parallel to the slope? 2. what is the component of f⃗ net perpendicular to the slope? 3. what is the magnitude of f⃗ net? 4. what is the direction of f⃗ net?

Scientist have use computer models to create a series of maps that show how susceptible coastal cities in island countries are to the sea rising at different levels.the map shows that a 1 meter rise would swap cities all along the us eastern seaboard. a 6-meter sea level rise with sub merge a large part of florida. thermal expansion has already raise the oceans 10 to 20 centimeters the most likely cause,directly and indirectly, for such a rise in sea level is
