Well, there was a need for more people working during the Industrial Revolution and it later would led to women working while wars went on and even The Women’s Suffrage
Answer:
The force applied will cause the object to be displaced from its equilibrium position.
However, the motion caused by the force on the object will be slight/minimal because of the small difference between the weight of the object and the force applied.
Explanation:
The weight of the object, W = 49.5 lbs
Force applied, F = 50 lbs
From the information given, it is observed that the force applied is greater than the weight of the object, i.e. F > W
Since, the force applied is greater than the weight of the object, the force applied is sufficient to cause a displacement of the object from the equilibrium position since it is known that the only cause of motion is force.
Answer:
Lighting significantly affects performance
Explanation:
In this study, Ellen took two groups and applied the same IQ test to both of them. The only variable that changed between the groups was the level of lighting in the room. The first group was placed in a room with very bright lights and the second group was placed in a room with more normal lighting.
Individuals in the first group did better in the IQ test and she found that the difference between the two scores was statistically significant.
We say that a result is <u>"statistically significant" when it is not likely to occur randomly but rather is likely to be attributable to a specific cause.</u>
<u />
So we can say that <u>the better performance in the first group tests were not likely to occur randomly but it can be attributable to a specific cause. </u>
<u></u>
<u>Since the only variable that was different between the groups was the lightning, we can conclude that lighting significantly affects performance. </u>
Answer:
Explanation:
Let's analyze each answer choice.
A. Gulf of Mexico: to the <u>south </u>of North America
B. Pacific Ocean: to the <em>west </em>of North America
C. Atlantic Ocean: to the <em>east </em>of North America
D. Arctic Ocean: to the <em>north</em> of North America
Since we want to find the body of water south of North America, the Gulf of Mexico is the correct answer.
Answer:
Naturalistic observation, interviews, and case studies
Explanation:
Three of the most common research methods are naturalistic observation, interviews, and case studies. Each one of them brings something different to the table:
- Naturalistic observation refers to studying subjects directly on their environment without any intervention from the researcher. This is a great method because watching people behave in a natural way will be very revealing and more truthful. When subjects know they are being observed, they often change their behaviour. Naturalistic observation thus requires the observer to be as anonymous and invisible as possible.
- An interview is a research method where the subject is asked to answer to some specific questions crafted by the researcher. Interviews allow the researchers have a much closer look at the subject, trying to ascertain the motives behind their behaviour. However, a problem with interviews is that the subjects often time won't respond truthfully, but will adjust their answers to what is expected from them.
- A case study is a method that goes more in depth than the other two, and the researcher tries to learn as much as possible about the subject through a variety of other methods, like observations, interviews, surveys, etc. Case studies are much thorough and deeper investigations, but they can be very time consuming, and require a subject that is willing to facilitate the work of the researcher, which isn't always possible.
