Final answer:
A sneeze can expel droplets from the mouth at about 50 miles per hour, which is why covering the mouth and nose is important to prevent the spread of pathogens.
Step-by-step explanation:
When a person sneezes, it can be quite powerful. A sneeze can eject tiny particles from the mouth at a high speed. The correct answer to the speed of a sneeze is C) 50 miles per hour.
Sneezing is an involuntary response to irritation in the nasal passage. The act of sneezing forcefully expels air, mucus, and pathogens out of the mouth and nose. To prevent the spread of respiratory pathogens, it's crucial to cover your mouth and nose when you sneeze, as these expelled droplets can carry thousands of pathogens.
Given how many diseases of the respiratory system are spread, understanding the force and speed of a sneeze highlights the importance of good hygiene practices in public health.
