Final answer:
The pulse strength, or amplitude, should be graded on a scale of 1-5, 1-10, 1-3, or 1-7 in Physics.
Step-by-step explanation:
The pulse strength, or amplitude, should be graded on a scale of a) 1-5, b) 1-10, c) 1-3, or d) 1-7. The amplitude of a pulse is a measurement of how far the medium is displaced momentarily from a position of rest. Different scales can be used to represent the range of amplitudes, such as the options provided in the question.
