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.
Experts think influenza may be spread to uninfected people in three ways: large-particle respiratory droplet transmission, airborne transmission, and contact (or fomite) transmission. Most experts think that influenza viruses are spread mainly by large-particle respiratory droplets produced when people infected with influenza cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled.
