A multithreaded web server wishes to keep track of the number of requests it services (known as hits). Consider the two following
strategies to prevent a race condition on the variable hits. The first
strategy is to use a basic mutex lock when updating hits:

int hits;
mutex lock hit lock;

hit lock. acquire();
hits++;
hit lock. release();

A second strategy is to use an atomic integer:

atomic t hits;
atomic inc(&hits);

Explain which of these two strategies is more efficient.

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.
