Question

which of the following options is a potential hazard in this investigation? burns from hot equipment after use. injury from dropping heavy masses on your feet. electrical shock from the equipment. sharp knives can cause injury. i dont know submit answer

Explanation:

Assuming the investigation involves handling heavy masses (common in physics - related experiments like mechanics), dropping heavy masses can lead to foot injuries. Hot equipment (if not used), electrical equipment (if not in use), and sharp knives (if not part of the investigation) are less likely hazards compared to heavy masses which are directly related to potential dropping and injury.

Answer:

Injury from dropping heavy masses on your feet.
