(d) The data density of a Blu-ray disk using a 405-nm laser is 1.5 × 107 bits mm −2
. Disks have an outside diameter
of 120 mm and a hole of 15-mm diameter. How many data bits can be contained on the disk? If a Blu-ray disk can
hold 9,400,000 pages of text, how many data bits are needed for a typed page? (Hint: Determine the area of the disk
that is available to hold data. The area inside a circle is given by A = πr2
, where the radius r is one-half of the
diameter.)

Amixture initially contains a, b, and c in the following concentrations: [a] = 0.300 m , [b] = 1.05 m , and [c] = 0.550 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.140 m and [c] = 0.710 m . calculate the value of the equilibrium constant, kc.

Calculate the concentration of all species in a 0.165 m solution of h2co3.

Alice did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. she placed a ray box in front of a mirror. she changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light. which of the following is the dependent variable in this experiment? the mirror used to reflect the light the ray box used as the source of light angle at which the light from the ray box strikes the mirror angle at which the mirror reflects the light from the ray box
