Which method of determining distance would be most appropriate for a ground-based observer trying to find accurate distances out to approximately 100 parsecs? (Choose the lowest applicable rung on the cosmic distance ladder.)

Answers

Answer 1

Answer:

Parallax                

Explanation:

            According to Mark Reid, an astronomer and an astrophysicist at Harvard Smithsonian Center, the Parallax method is the most accurate method to find distance in astronomy as it includes only geometry.

          Astronomers determine the distance of heavenly objects in the space by a method known as the trigonometric parallax or the stellar parallax.

            To measure a very large distances in space, for example the distance between a star or a  planet from Earth, the astronomers uses parallax principle. Here, parallax is defined as a semi-angle made by the inclination between the two sight-lines and the star, and this observation is taken when our Earth is on the opposite sides of  Sun.

Hence the answer is --- Parallax method.

A perceptual set is a a. tendency to fill in gaps to perceive a complete, whole object. b. readiness to perceive an object in an unfairly negative fashion. c. tendency to view objects higher in our field of vision as closer. d. mental predisposition that influences what we perceive. e. conditioned response to a perceived event.

Answers

Answer:

d)

Explanation:

In psychology, the term perceptual set refers to the tendency to perceive things in a certain way. This means that we tend to notice only certain aspects of an object or situation while ignoring other details according to our own past experiences or prejudices or expectancies.

Thus, we can conclude that a perceptual set would be d) mental predisposition that influence what we perceive.

Note:

a) Perceptual sets do not refer to the tendency to fill in gaps to perceive a complete object but rather to the fact that we do not perceive the object in its completeness.

b) Perceptual sets do not imply an unfairly negative perception but rather to not perceive things as a whole.

c) Again, perceptual sets don't refer to field of vision.

e) Perceptual sets are not necessarily conditioned responses.

Final answer:

A perceptual set is a d. mental predisposition that influences what we perceive.

Explanation:

A perceptual set is a mental predisposition that influences what we perceive. It can involve perceiving objects in certain ways based on beliefs and expectations and filling in missing information to see complete objects. The perceptual set can also lead to unfairly negative perceptions. For example, if we expect to see a certain object in a specific context, we may be more likely to perceive it even if it's not actually there.

Similarly, if we have a negative bias towards a particular object or person, we may perceive them in an unfairly negative fashion. The perceptual set can also influence how we fill in gaps in our perception to perceive a complete, whole object. This process is known as closure, where our brain fills in missing information based on our perceptual set.

a) is an example of a stereotype threat
b) may help her live a longer life
c) suggests that she is in denial
d) is consistent with the prevailing Western stereotype of late adulthood

Dominique is a recently divorced woman in her 30s who experienced some intimate partner violence during her previous marriage. According to research, what might Dominique's experiences with future intimate relationships be like after experiencing intimate partner violence?

A. Research does not show it impacting future relationships so we cannot predict what will happen.
B. After experiencing abuse, her odds of establishing a long-term stable relationship are lower.
C. It is highly likely she will experience the same type of abuse again in her next relationship.
D. After experiencing abuse, her odds of establishing a long-term stable relationship are higher.

Answers

Research does not show it impacting future relationships so we cannot predict what will happen.

Answer: Option A

Explanation:

Abuse in a relationship will result in emotional abuse. It can be verbal assault, control over partner, isolation, degradation, and dominance. It affects the person emotionally, psychologically and physically. It will completely affect the well-being of a person. As time goes by the severity of the abuse can also increase.

The effect of emotional abuse can be reduced with time and the help of matured experts who is strong with the social support network. If not the fear of chances of being victimized again increases while thinking about the relationships in the future. In the case of Dominique, we cannot predict the future of her.

Final answer:

Dominique's odds of establishing a long-term stable relationship are generally lower after experiencing intimate partner violence, due to the lasting psychological effects and potential barriers to forming healthy relationships.

Explanation:

According to research, after experiencing intimate partner violence (IPV), Dominique's odds of establishing a long-term stable relationship are generally lower. This outcome is due in part to the complex and lasting impacts that abuse can have on an individual's mental health and their ability to trust future partners. Experiences such as IPV can lead to an increased risk of substance abuse, and mental health issues like depression or anxiety, and may affect future relationship patterns.

Furthermore, empirical evidence suggests that IPV often takes a long-term psychological toll on victims, affecting their sense of self-worth and creating potential barriers to forming healthy, solid relationships. It is also important to note that while there is a chance of a repeat of the same type of abuse in future relationships, it's not a foregone conclusion; survivors of IPV can seek therapy and support that might enable better outcomes in future intimate relationships.

Answers

Answer:

Explanation:

the parents are missing

Final answer:

The situation describes an extended family structure where Sahara is being raised by her maternal grandmother due to her parents' unavailability. These multigenerational households are relatively common and involve grandparents or relatives providing caregiving in the absence of biological parents.

Explanation:

The scenario described shows that Sahara, a young girl, is living in a household with her maternal grandmother, with absent parents due to incarceration and addiction. This family arrangement is known as an extended family, which is a type of family structure where a child is raised by relatives other than their biological or adoptive parents. In Sahara's case, the extended family member is her grandmother. The scenario highlights a situation where intergenerational relationships are key, and the support provided by extended family members is crucial in the absence of the parents.

As stipulated by researchers and observers, multigenerational family systems are becoming more common. Such family structures often have three generations living together, where grandparents play a supportive role in raising grandchildren and may also provide care to their own aging relatives within the same household. Additionally, the concept of family structures encompasses various household arrangements defined by legal or blood relationships and typically includes at least one child under 18 years of age.

At one time Jimmy was scared of dogs because he was bitten by one. With subsequent repeated exposure to tame dogs in safe settings, however, his fear of dogs has gradually faded. Jimmy's diminishing fear of dogs best illustrates______.

Answers

Answer:

Extinction

Explanation:

In classical conditioning, the term extinction refers to the disappearance of a previously learned behavior.

Extinction usually happens when the behavior stops being reinforced or the individual goes through a process of 'unlearning' the behavior by starting making new associations until the original behavior does not longer appears.

In this example, Jimmy got bitten by one dog and he started being scared of dogs, thus, this is a learned behavior that he has. However, he was exposed to dogs in safe settings and his fear has faded now: Jimmy went through a process in which he 'unlearned' the behavior of fear and now this fear has faded.

Therefore we can conclude that this is an example of Extinction.

Which is not considered a strategy for commiting information to one's long-term memory? Group of answer choices a) Link the information to other information you already have stored. b) Mentally group similar individual items into buckets. c) Try to recall information amongst distractions. d) Break information down into manageable chunks.

Answers

"Try to recall information among distractions" is not taken a strategy for "committing information" to "one's long-term memory".

Option: C

Explanation:

Humans store information in two parts one is short-term memory called as temporary store and long-term memory which is known as relatively permanent store. To fetch out information from one's long term memory being in distracted situation can never result good but distributing information into manageable small chits, linking information with stored ideas, categorizing information etc such things can be approximately productive to conclude the need of information.

Final answer:

The strategy that is not considered a strategy for committing information to long-term memory is to try to recall information amongst distractions. Linking information to other information, mentally grouping similar items, and breaking information into manageable chunks are effective strategies for committing information to long-term memory.

Explanation:

The strategy that is not considered a strategy for committing information to long-term memory is c) Try to recall information amongst distractions.

Recalling information amongst distractions actually hinders the process of encoding and consolidating information into long-term memory. Distractions can interfere with attention and focus, which are crucial for effective encoding and consolidation.

On the other hand, the other strategies mentioned, such as linking the information to other information already stored, mentally grouping similar items into buckets, and breaking information down into manageable chunks, are all effective strategies for committing information to long-term memory.
