Answer:
All people with the observant trait are often a steadying force that always wants to get things done. Their energy is very elegant in the sense of working on real things in real time.
Explanation:
Hope I helped
The chemical senses are the senses of smell (olfaction) and taste (gustation).
The frictional force is oposing the force that we apply to this mass. Therefore the overall force is

The second principle of physics tells us that the acceleration of a mass is direct proportional to the applied force, the mass of that object being the proportionality constant.

Hence
55 Kg has a weight of 55x9.8= 539 N
That is equal to the Normal force.
The static friction = 0.19 x 539 = 102.4 N
No, there were other scientists who developed the cell theory with him.
