On the Moon they would weigh only 200 N. The astronaut's mass is 120kg wherever they are. The weight of an object changes if the strength of gravity changes. Remember: a mass of 1 kg has a weight of about 10 N on Earth.
The droplets in the air may be breathed in by those nearby. Spread can also occur by touching the nose or mouth with droplet contaminated hands. Examples of droplet spread diseases: 1  common cold. 2  flu. 3  meningococcal disease. 4  rubella.
Droplets can be generated from the source person during coughing, sneezing, talking and during the performance of certain procedures such as suctioning or bronchoscopy. Droplets may contain microorganisms and generally travel no more than 3 feet from the patient. These droplets can be deposited on the hostâs nasal mucosa, conjunctivae or mouth. Diseases requiring droplet precautions include, but are not limited to: Pertussis, Influenza, Diphtheria and invasive Neisseria meningitidis.
