Answer:
1.65×10⁻⁶ N
Explanation:
m = Mass of ant = 
r = Radius = 50 m
t = Time taken to complete on rotation = 60 seconds
Angular velocity

Centripetal acceleration is force that is acting outward

The magnitude of the upward force felt by the ant due to the second hand would be 1.65×10⁻⁶ N
1. I don't see a graph
2. It could be because a liquid could be evaporating in the process
3. It could be that the liquid is getting colder
4. 1 liquid is medium and moving a the normal pace
Explanation:
The five basic postulate of kinetic molecular theory includes:
1) All gases consist of large amount and numbers of tiny particles that are far apart from each other and also relative to their size.
2) The collisions between gas particles and gas particles against container walls is refer to as elastic collision.
3) All gas particles are in a continuous random and rapid motion. They possess kinetic energy which is energy of motion.
4) There are no attractive force between gas particles.
5) The temperature of a gas depends on the average kinetic energy of the gas particle.
