Suppose that the user code incurs an exception kat an instruction. Which of the following are ways in which the kernel code's handler for exception k may cause the user code to resume execution? (Select all that apply.)

a. Execution of the user code resumes by restarting at the first instruction.

b. Execution of the user code resumes by retrying the current instruction.

c. Execution of the user code resumes at the next instruction.

d. Execution of the user code does not resume at all.

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.
