What is the speed of air inside our body at the time of sneezing?

Mainstream understanding is that a sneeze is 100 mph, or ~45 m/s. However, this isn't even close to being true.. A study in 2013 (see link below) was conducted where they investigated the airflow dynamics of sneezing and breathing, and discovered that the highest velocities of a sneeze are around 10 mph, or 4.5 m/s.

Explanation:

i think this picture will you.

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
