The final temperature is 50.8degrees celcius
Explanation:
Pls refer to attached handwritten document
Answer:
Pressure
Surface
Flow
Fluency
Explanation:
*Surface
The surface tension is the force with which the surface molecules of a liquid are attracted to bring them inside and thus decrease the surface area.
*Flow
It is defined as resistance to flow. The viscosity of a liquid depends on the intermolecular forces:
-The higher the intermolecular forces of a liquid, its molecules have a greater difficulty moving between them, therefore the substance is more viscous.
-Liquids that are made up of long, flexible molecules that can bend and tangle with each other are more viscous.
* Pressure
if the molecules of the liquid have a greater intensity of intermolecular force, then they will be trapped in the liquid and will have less facility to pass into the gas phase.
on the contrary to lower intensity of intermolecular force, then the molecules can escape more easily to the gaseous state.
*Fluency
This property allows liquids to easily pass through a hole regardless of size, as long as this hole is at a lower or the same level of the container where the liquid is stored.
This property indicates the deformability of a liquid which is very wide without requiring mechanical stress.

Answer:
Surely Achilles will catch the Tortoise, in 400 seconds
Explanation:
The problem itself reduces the interval of time many times, almost reaching zero. However, if we assume the interval constant, then it is clear that in two hours Achilles already has surpassed the Tortoise (20 miles while the Tortoise only 3).
To calculate the time, we use kinematic expression for constant speed:
The moment that Achilles catch the tortoise is found by setting the same final position for both (and same time as well, since both start at the same time):

C. is responsible for sliding friction and contact forces
