Question

Weight on Earth (lbs.) : 600N or 132lb

You get back in your space shuttle to continue on your trip. Your next stop is Jupiter you've heard that its moons arebeautiful You open up your "Outer Space Tourbook to the page about Jupiter's moons and start to read... You discover that there are over 30 moons, and that one of them- Europa - has an ocean of liquid water on its surface, protected from cold space by a thicklayer ofice While its radius is only of the Earth'sradius R1500 km). its ocean is twice the volume of Earth's oceans! In addition to its ice layer and ocean, Europa has a rocky mantle and a metalliciron core, a composition similar to Earth's. Average 3.0 /cm 0.934 E cm 700 m Iron Core Mantle Water Ocean 680 m 100 m 20 m Ice As you arrive in Europa, you see that Jovian tourism department has built tunnels that burrow deep into Europa (a total of 700 m), which allowvisitors to see the inside of the planet- including the ocean!- through its walls Asyou begin to tunnel in, you not only admire its oceans, but you begin to feel a change in the gravitational force from the moon. As you fly deeper into the moon, make a prediction for how you think the gravitational force will change. Will it increase or decrease? Why? Turrel Interior of Europa Woter oc

Calculate the gravitational force you feel at the following places. Show your work.

(a)500 km above the surface of Europa.

(b)At the surface of Europa.

(c)Inside the tunnel, half-way through the ocean layer.

(d)At the bottom of the tunnel.

(e)Evaluate the prediction you made earlier. Did the gravitational force change as you expected? Explain.
