  • What is the mass of 211mL of a liquid that has a density of . . . - Socratic
    Approx 190*g By definition, rho, is given by the quotient rho_"density"="mass" "volume", and thus has units of g*mL^-1-=g*cm^-3 And so we simply rearrange
  • Question #c7924 - Socratic
    Explanation: Given point #-> (x,y)-> (-3,10)# Given gradient #" " (m) =-2# Thus #y=mx+c" "# becomes #" " y=-2x+c# '~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ #color (blue
  • Question #021e1 - Socratic
    36 neutrons One way we have of differentiating between various nuclides of the same element is by writing the name of the element followed by a hyphen and the mass number of the nuclide In your case, you would have zinc-66, a nuclide of zinc that has a mass number equal to 66 Now, an atom's mass number, A, tells you the number of protons, which is given by the atomic number, Z, and neutrons
  • Google Lens - Search What You See - Socratic
    Discover how Lens in the Google app can help you explore the world around you Use your phone's camera to search what you see in an entirely new way
  • Question #06d1b - Socratic
    From the Law for conservation of momentum we have for an incompressible fluid of density rho moving with velocity v the rate of change of momentum in the direction of motion x of fluid - (dp) dx = rho u (du) (dx) Rewriting it as (dp) dx + rho u (du) (dx)=0 For a constant density (incompressible flow) we can take the multiplicant rho u inside the differential It becomes (dp) dx + (d(1 2 rho u
  • Question #cfae5 - Socratic
    a=0, 4 we will use the scalar (dot) product for two vectors veca=a_1hati+a_2hatj+a_3hatk," "vecb=b_1hati+b_2hatj+b_3hatk veca*vecb=|veca||vecb|costheta----(1) theta
  • Question #d35ab - Socratic
    It abolished Slavery Slavery was abolished in the United States in 1865 with the 13th amendment The emancipation proclamation signed on August the 28th in 1863 only freed the slaves in the Confederacy Some states like Kentucky had refused to secede despite their practising slavery and Lincoln needed their support at all costs
  • Question #19ef1 - Socratic
    W=8 31d^3 = 8 31 * 7^3 =8 31 * 343 ~= 2850 The trick here is to guess what the variables in the equation mean In this case we have W and d The question asks us to determine weight, and gives us diameter From this we guess that W implies weight and d implies diameter Since the diameter was given to be 7 feet, we can substitute that into the equation: W=8 31d^3 = 8 31 * 7^3 =8 31 * 343
  • Question #8a78e - Socratic
    Lustrous Malleable Ductile Good conductors of heat and electricity These are four primary characteristics of metals, but there are many others as well Metals tend to exhibit luster; that is, they appear to "shine" due to how light interacts with their surfaces Metals tend to exhibit malleability, which means they can be deformed under compressive stress; i e they can be compressed into thin
  • Question #6a1e0 - Socratic
    6 8 * 10^(-5) The thing to remember here is that in order to have 1 mole of xenon difluoride, you need to have 6 022 * 10^(23) molecules of xenon difluoride This number, which is known as Avogadro's constant, is essentially the definition of the mole So 1 mole of a given substance will always contain 6 022 * 10^(23) atoms molecules ions, whatever the case may be, of that substance You can
