Explanation:
It can tell us that Neanderthals were practical: perhaps they buried their dead so as not to attract scavengers or spare themselves the smell of a decomposing corpse. But it also tells us that they gave death the respect it deserves:
Answer: Inattentional blindness
Explanation: Simply this phenomenon occurs due to the perceptual preoccupation with certain subjects, in this case white shirts, which is why they do not see certain phenomena, although they are within the field of view of the participants. That is why this blindness is also called perceptual blindness. In other words, participants' perceptions were influenced by being told to focus only on white shirts, and their perception was somehow "directed". Because of this, half of the participants did not see man wearing the black gorilla costume, if he was in some white costume, the participants would probably have seen him.
Observational methods, case-study methods and survey methods.
Observational Method
With the observational method (sometimes referred to as field observation) animal and human behavior is closely observed. There are two main categories of the observational method — naturalistic observation and laboratory observation.
Case Study Method
Case study research involves an in-depth study of an individual or group of indviduals. Case studies often lead to testable hypotheses and allow us to study rare phenomena. Case studies should not be used to determine cause and effect, and they have limited use for making accurate predictions.
Survey Method
In survey method research, participants answer questions administered through interviews or questionnaires. After participants answer the questions, researchers describe the responses given. In order for the survey to be both reliable and valid it is important that the questions are constructed properly. Questions should be written so they are clear and easy to comprehend.
Answer:
Because wind is able to do work.
Explanation:
Work has different definition in physics and economic.
In physics, work refers to a transfer of energy to a certain object that is caused by the use of force in the direction of the displacement.
Let's take windmill as an example.
Windmill utilize the force of wind to generate electricity. This could only happen because wind could produce kinetic energy that is directed to rotate the generator within the windmill. This rotation of the generator is what produced the electricity. This process wouldn't be possible if wind does not have energy.
