Suppose a ROM holds a total of 8192 bits.
(a) How many bits long would the individual addresses have to be?
(b) If the bits are organized into 8-bit memory words or bytes, how many words would there be, and how many bits long would the addresses have to be?
(c) How is such a ROM described?
(d) If each location requires its own word line emanating from a decoder AND gate, how many gates would the decoder for 1K-byte ROM have to contain?
(e) Develop a two-dimensional addressing system using a 6-to-64 decoder, a 64-word×128- bit matrix, and 16-input multiplexers. How many gates would such a system require?
When algae growing in water containing only 16O were furnished carbon dioxide containing 18O, no 18O was found to be evolved from the oxygen gas produced. What conclusions about photosynthesis can be drawn from these experiments?
A string of negligible diameter is drawn down the center-line of a pipe containing a Newtonian fluid. At what velocity, w, must the string be drawn in order to vaporize the fluid?
1 kg of liquid water, initially at 40 °C, 2 bar, is heated under constant pressure. If the amount of heat added is 1200 kJ, determine the final temperature and the phase of the system in the final state (if vapor-liquid mixture, report the mass fr..
Discuss how transmission electron microscopy (TEM) can provide information complementary to that which can be obtained from standard X-ray or neutron diffraction methods, giving suitable examples.
Methyl ethyl ketone (MEK) is manufactured by the dehydrogenation of 2-butanol using a shell and tube type reactor. Flue gases are used for heating and pass though the tubes. The flue gases will contain traces of sulfur dioxide.
