If you measure my hairline you will get about 90°
Answer:
Repetition
Explanation:
The best term to describe this example is repetition and not replication.
Most times, to obtain an accurate and precise reading which is reliable, scientist makes several repeated measurements. The average gives the most reliable representation of the phenomenon being tested.
This process is called repetition.
On the other hand, duplicating an experiment is replication. Experiments are replicated to proof their validity.
- Since this is a brand new experiment where 16 height measurements are reported, we are dealing with a repetition situation.
This interaction must be one of the intermolecular forces, particularly, Van der Waals forces. From the description given, this force is called <em>induced dipole-induced dipole forces</em>. Dipole is defined as the separation of positive and negative charges. This type of intermolecular force is very weak compared to hydrogen bonding.
Solution is not a pure substance b/c it is mixture of two substance
