If two 50-N weights are attached to the opposite ends of a spring scale, and allowed to hang off the sides of the table upon which the spring scale rests, what is the tension
force on the spring scale in Newtons? (what is the reading on the scale?)
O a. Tension = 50 N
O b. Tension = 200 N
O c. Tension = 100 N
O d. Tension = ON

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
