  1. 4 dni temu · Archimedes’ principle is very useful for calculating the volume of an object that does not have a regular shape. The oddly shaped object can be submerged, and the volume of the fluid displaced is equal to the volume of the object. It can also be used in calculating the density or specific gravity of an object.

  2. In this course, we will focus on oscillations in one dimension. Let’s consider a thin string of length \(l\) that is fixed at its two endpoints, and let’s call the displacement of the string from its horizontal position \(u(x,t)\) (figure [fig:pde1]).

  3. 3 dni temu · The formula for calculating the density of an object using water displacement is given by: \ [ D = \frac {m} {FW - IW} \] where: \ (D\) is the density in grams per cubic centimeter (g/cm³), \ (m\) is the mass of the object in grams, \ (FW\) is the final water level in milliliters (mL), \ (IW\) is the initial water level in milliliters (mL).

  4. 4 dni temu · First, write the unbalanced equation: C8H18 + O2 → CO2 + H2O. To balance H, add a coefficient of 9 in front of H2O. C8H18 + O2 → CO2 + 9 H2O. To balance C, add a coefficient of 8 in front of CO2: C8H18 + O2 → 8 CO2 + 9 H2O. To balance O, add the fractional coefficient 25/2 in front of O2:

  5. 4 dni temu · Use the drop-down menus to label each of the following changes P for physical change and C for chemical change. C The substance changes to a new substance. C The original substance can be recovered. C The color changes. C Gas is produced and given off. C The substance changes size, shape, or volume.

  6. 4 dni temu · How much water you need depends on your metal - test it out first - figure out how much water is needed to completely cover the metal when it is in the calorimeter. Take mass of your metal. Add it into a large test tube. Heat metal in water bath to boiling, then heat 10 more minutes.

  7. 1 dzień temu · The image series is converted to grayscale. The particles were calculated as objects by their white area in terms of a min-max interval assumed within particle range. The identified contours were used to calculate the center of mass for each object to get a local coordinate (x-y position).
