Homework Statement When searching for gold, measurements of g can be used find regions within the Earth where the density is larger than that of normal soil. Such measurements can also be used to find regions in which the density of the Earth is smaller than normal soil; such regions might...

Yes, it is basically an [B]X[B] with a ball in the middle.

Homework Statement An abstract sculpture is constructed by suspending a sphere of polished rock along the vertical with four cables connected to a square wooden frame 1.7 m. If the stone has mass m = 5.2 kg, and the bottom two cables are under a tension of 25 N each, what is the tension in...

Thanks, I wasn't able to get it right but I appreciate your help!

How do I use radius to calculate volume? What is the equation to do that? Thanks

Homework Statement Consider a hypothetical extra*solar world, planet X, that has 2.2 times the radius of the Earth and 2.5 times its density. What is the acceleration due to gravity on the surface of planet X? Homework Equations g=GM/r^2 The Attempt at a Solution I am not...

Average velocity takes into account total displacement and time while speed does not take into account direction.

The problem asks for both. I am just not sure how to solve either one.

I think that I have to include the distance but how do I find that?

I subtracted because I was using the average velocity formula in my book. Final displacement-Inital displacement/ final time-initial time. Without subracting, I got 8969.51m/s which is also not the correct answer.

Homework Statement The space shuttle takes off from Cape Canaveral in Florida and orbits Earth 18 times before landing back at Cape Canaveral 23 hours and 7 minutes later. During this time, it moves in circular orbit with radius 6.6 x10^6 m. Homework Equations The equation that I am...

Thanks, I figured it out. It was really easy and it really was staring me in the face!

Vectors (HELP!) Homework Statement Consider a map oriented so that the x-axis runs east*west (with east being the “positive” direction), and y runs north*south (with north “positive”). A person drives 47 km to the west, then turns and drives 156 km towards the south. Find x and y...
