Note: in mathematics, the square root of a negative number is not real; in java therefore, passing such a value to the square root function returns a value known as nan (not-a-number). given a double variable named areaofsquare write the necessary code to read in a value, the area of some square, into areaofsquare and print out the length of the side of that square. however: if any value read in is not valid input, just print the message "invalid". assume the availability of a variable, stdin, that references a scanner object associated with standard input

Acomputer has a two-level cache. suppose that 60% of the memory references hit on the first level cache, 35% hit on the second level, and 5% miss. the access times are 5 nsec, 15 nsec, and 60 nsec, respectively, where the times for the level 2 cache and memory start counting at the moment it is known that they are needed (e.g., a level 2 cache access does not even start until the level 1 cache miss occurs). what is the average access time?

Scientists have changed the model of the atom as they have gathered new evidence. one of the atomic models is shown below. what experimental evidence led to the development of this atomic model from the one before it? a few of the positive particles aimed at a gold foil seemed to bounce back. the colors of light emitted from heated atoms had very specific energies. experiments with water vapor showed that elements combine in specific proportions. cathode rays were bent in the same way whenever a magnet was brought near them.
