Assume that an in-order execution processor has a CPI of 1.2 excluding memory accesses. 30% of all instructions are load/store instructions that generate memory accesses for data. The L1 cache has a hit time of 1 cycle and a miss rate of 10%; and the L2 cache has a hit time of 12 cycles, a miss rate of 20%, and a miss penalty of 100 cycles. (1) What is the average memory 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.
