Iceland is a unique land mass, as it gives scientists the opportunity to study processes that normally occur at a submerged (underground) divergent plate boundary. the diagram shows that two tectonic plates meet in iceland: the north american and the eurasian plates, as shown in the diagram below. as these plates drift away from one another, a rift (like those normally found on the ocean floor) will be created. what chain of events will most likely occur to iceland in the future?

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when you push the platform, you compress the springs. you do an amount of work of 79.0 j when you compress the springs a distance of 0.230 m from their uncompressed length. (a) what magnitude of force must you apply to hold the platform in this position? (b)how much additional work must you do to move the platform a distance 0.230 m farther? (c) what maximum force must you apply to move the platform a distance 0.230 m farther?
