What is newton's second law of motion?

forces are balanced when they are equal and opposite.

an object at rest or in motion will remain at rest or in motion unless acted upon by an unbalanced force.

the smaller the mass of an object, the greater the acceleration of that object when a force is applied.

the greater the force applied, the greater the acceleration.
every reaction is equal to the force applied.

Which of the following is the result of the nuclear weak force? the instability of large nuclei the repelling force between positively charged protons the structure of the atom certain types of nuclear decay

What are similarities and differences between refraction, reflection, diffraction and absorption?

Consider a file currently consisting of 200 blocks. assume that the file control block (and the index block in the case of indexed allocation) is already in memory. calculate how many disk i/o operations are required for contiguous, linked, and indexed (single-level) allocation strategies, for each of the conditions listed below. in the contiguous-allocation case, assume that there is not room to grow at the beginning but there is room to grow at the end. also assume that the block information to be added is stored in memory.
