Physics A female skater is spinning at 1 rev/s with her arms outstretched so that her moment of inertia is 3.6 kg by m squared. She then pulls her arms to her sides, which reduces her moment of inertia to 1.2 kg by m squared. What is her angular velocity?

A ship with a waterline area of 20000 square meter has vertical sides at the water line plane. In seawater with density of 1025kg/cubic meters, the draught of the ship is 3meter.I am confused,

The weight of the ship is 20,000*3*1,025 = 61,500,000 kg; To have a 3m draught in fresh water, it would have to weigh 20,000*3*1000 = 60,000,000 kg; That means it needs to remove 1,500,000 kg (1,500 T) of cargo before sailing into fresh water.

Why do planets orbit the sun

In a word, gravity. The solar system is thought to have formed from a rotating disk of dust and gas with clumps in it. As these contracted the whirling sped up, like a skater drawing in her arms.

There is a law called the conservation of momentum which meant that when planets eventually pulled together in lumps, due to gravity, the spinning of each, and the spinning around the Sun, stayed on.

The Sun has held all this activity to itself in orbit by its massive gravity, which is still felt way out past Pluto.

What is form?

Form is the stance of an archer when they shoot. The ideal form is for an outstretched and slightly flexed bow arm and a flexed horizontal and flexed bowstring arm at full draw. You should resemble the letter T.

I have a 2000 gmc Jimmy . I'm going to change the

Locate the idler pulley to the left of the crankshaft pulley. The idler pulley bolts to the idler arm. The idler pulley is replaced with the arm because they are sold as one unit.

  • 2 Place a 3/8-inch ratchet driver into the square hole on the face of the idler pulley and pull up on the handle. This releases tension on the Sonoma's serpentine belt. Pull the belt off the idler pulley, lower and remove the ratchet handle.
  • 3 Remove the two bolts that secure the idler arm to the engine block using a socket and ratchet, and discard the old idler arm.
  • 4 Place the new idler arm against the engine block and secure it using the socket and ratchet.
  • 5 Put the ratchet driver into the square hole on the new idler pulley, pull up on the handle and place the serpentine belt over the pulley.
  • 6 Lower and remove the ratchet handle.

    Doing a physics problem and when dividing i am getting wrong exponents coming up as E16 when should be E4

    In scientific problems the powers of 10 are the easiest thing to handle if you keep in mind two or three rules.
    1. 1/10^(a) = 10^(-a)
    2. (10^a)*(10^b) = 10^(a+b)
    3. (10^a)/(10^b) = 10^(a-b)
    4. (10^a)^b=10^(a*b)
    Example : suppose you want to calculate the charge to mass ratio of the electon
    m_e= 9.109534 E-31 kg
    q_e=1.6021892 E-19 C

    q_e/m_e= (1.6021892/9.109534)* (E-19)*(E 31) C/kg
    q_e/m_e= (1.6021892/9.109534)* (E 31-19) C/kg
    q_e/m_e= (1.758804786 E-1)* (E 12) C/kg
    q_e/m_e= 1.7588048 E 11 C/kg

    If you just use your calculator to operate on the mantissas (multiplications and divisions) and handle the powers of 10 by hand, you will make fewer errors, especially if you are not confident in your mastery of the calculator as regards exponents.

    Anyway, if you could give us a sample of the divisions you are performing, we might be able to help you. Post a comment to this thread and we will take it from there.

    Replacing the alternater

    1. Unhook the battery.
    2. Find the pulley the serpentine belt runs on that isn't running anything. This is your tension pulley and it should have a square hole in it or the arm the pulley is bolted too that fits a 1/2" socket ratchet. Put that in the square hole and pull so it loosens the tension on the belt so you can remove it from the alternator pulley. Take note to how the belt goes on before taking off.
    3. Take the 2-3 bolts off that hold the alternator in place.
    4. Take wire connector plug off of alternator.

    And you should have an alternator out of your car.

    Good Luck

    Tensioner pulley

    This doesn't sound like a problem with your idler pulley to me, more like an axle or wheel bearing? But to check your pully just pull it back with the correct tool, some use a square 3/8 or 1/2 regular socket drive and a breakover works great. some you can just get the correct size boxend wrench on it and pull it back, after you have the tension off the belt remove the belt, spin idler pully and see if it is bad, try and wiggle the arm back and forth with a pry bar. it should have very little play in it. I hope this helps you Isolate your problem and Merry Christmas!
