Answer: Construct validity
Explanation:
Construct validity is the degree to which a test is done to measure what it claims. Construct validity defines how well the test or experiment actually measures its claims and whether the operational definition of the variable reflect the true theoretical meaning of the concept being illustrated.
The psychologist develops a questionnaire that is designed to study the variable of self-esteem and then conducts different studies to investigate the differences between people who had low scores on sled esteem and the people who had high score on self esteem. The reason for this was to get an accurate method of measuring self esteem. This means the psychologist wants to establish construct validity.
Answer: True
Explanation:
In a coal-fixed power station, coal is burnt to heat up water which then turns into steam. This steam is then channelled to turbines that are connected to generators. When the steam makes the turbine turn, electricity is produced by the generators.
These are the main type of plants used in the developing world to create electricity however they cause a lot of pollution, particularly of air.
Industrial cities began to develop because of new technologies and ideas and in order for the factories to grow larger, they needed more workers so the the unemployed people had those opportunities to work there.
Answer:
Sharks swallowed and ate the bodies of African slaves that were thrown into the sea.
Explanation:
The middle passage is a stage in the triangular trade where Slaves from the African coasts were carried across the Atlantic ocean to South and North America. In the course of crossing this ocean, some slaves became so weak that they could no longer continue the journey. Some others died from the stress and starvation they experienced in the course of the journey. This set of people were usually thrown into the ocean by their captors and their bodies were readily swallowed by the sharks.
It is believed that some of these sharks followed the ships closely so as to readily grab the opportunity of swallowing the slaves when they were thrown aboard.
