What is the gravitational acceleration at a distance of R/2 from a the center of a planet?

  1. Given that the radius of the first planet is R = 2.87 x 10^6m and M = 6.02 x 10^24 kg. The idea is the radius is reduced in half and we now have to calculate a new gravitational acceleration. I would appreciate the help on this... I don't even think it's necessarily a killer problem just stumped. Thanks!

    Answer by lunchtime_browser
    The gravitational force (F) between two masses (M and m) separated by a distance R is given by: F = GMm/R² When one of the masses (M) is a planet and the other mass (m) is a small object near the surface of the planet, we have a special name for that gravitational force: we call it the weight of m. Weight = mg where g is the acceleration due to gravity. So we can write: mg = GMm/R² m cancels out, leaving: g = GM/R² The rest is just plugging in the numbers. EDIT: Just reading your question again. It's not clear how the "new" planet comes about. The new radius, Rn, will obviously be R/2 = 1.435 * 10^6 m, but how is this being achieved? Is the same mass M being compressed into the smaller volume, so that the density of the smaller planet is increased, or is the planet just made up of less "stuff" than the first planet (but at the same density) in which case the new planetary mass Mn will be smaller: {Mn = M/8} ?

  2. W = F * delta r Just curious what lower case r stands for? It's beginning college physics to answer your question, I never took physics and high school. I don't care much for my professors teaching methods but that makes more sense so essentially all I'm looking at is a simple formula to measure the work based off of force and distance. I think I got it thank you for your input.

    Answer by †Archangel TJ†
    if it's high school physics. W = work. F = force , delta r = distance moved

  3. 8^2- r^2=r(8)+43 solve for r. I set it up like this, 64-r^2=8r+43 but I don't know how to solve for r since its squared. Please show the steps you took to get r=?

    Answer by Me
    64 - r^2 = 8r + 43 move all terms to 1 side r^2 + 8r - 21 = 0 use discriminant method to solve r = -4 +/-sqrt(37)

Hmm ? – Good Advice On How To Build More Muscle

Consume lots of protein when you wish to build muscle. Protein provides the building blocks that create muscles. If you fail to get a sufficient quantity, it will be hard for you to gain muscle mass. Strive to consume lean, healthy proteins with at least two of your three meals. Eating enough protein is a great way to build muscle. One of the best ways to get the protein that you need is by utilizing protein shakes and supplements. The best times to consume these supplements is right after working out and before bed. To replace fat with muscle faster, consume at least one protein shake a day. If your goal is bulk, then consider drinking a protein shake with every meal. Getting protein through your diet and supplements is key when working to build muscle. Before working out, consume 20 grams (or more) of whey protein. This will give your muscle recovery a jump start, and lower the possibility of your muscles being used for workout fuel. You need to eat Start Reading Whole Lot More Start Reading Whole Lot More

My Condo is My First Real Home

Washington DC and Potomac RiverLately, I have had such a bad run of luck. It all came to a head a few months ago when I lost my apartment due to a fire. Though it didn't completely burn down, I knew that it would have to be rebuilt from the ground up before I could move back in there. I decided to change my luck on my own, and I started to look at mclean va condos. I figured if I was going to move, I might as well move into a place that I owned instead of giving someone else money every month and not having much to show for it.

I was able to find a really nice condo not too far from where I work, and there were actually several units available. I looked at each one, and I was surprised that they weren't exactly alike. I liked the one that had the larger living room and a smaller kitchen, because I rarely do any cooking at home. I would much rather have the extra space in the room that I would be spending the majority of my time in. I was able to buy all new furniture because of my renter's insurance policy, so it was not long before I had an even nicer place to live.

I have had a lot of compliments on my new home, and I am pretty excited that I am actually putting money toward something tangible. I like every single room, and have put my own touch in each of them. I never thought I wanted to be tied down to a home, but I realized how untrue that was when I lost everything in the apartment fire. I love my new home, and I take a pride in it that I never had before.
