Answer:

Science experiment: Inclined plane

(Your name)

8th grade AP Science

(Teachers name)

(todays date or due date)

Hypothesis:

If the height of the inclined plane increases, then the IMA, AMA will increase And efficiency will decrease. This will be because a sharper incline will require more energy over a shorter distance than a shallow incline.

Trial: 1

Height: 11.15 Cm

Length: 56.60 Cm

Mass: 500 g (4.90 N)

Effort Force: 1.35 N

AMA: 3.63

IMA: 5.08

Efficiency: 71.46

Trial: 2

Height: 17.40 Cm

Length: 56.60 Cm

Mass: 500 g (4.90 N)

Effort force: 1.75 N

AMA: 2.80

IMA: 3.25

Efficiency: 86.15

 

Questions for “presenting your outcome”:

How does the length to height ratio (the IMA) of trial 1 compare to trial 2?

Why is the actual mechanical advantage less than the ideal mechanical advantage in each of the trials?

If a machine was 100% efficient, how would the AMA compare to the IMA?

Answers to those questions:

1: The IMA in trial 1 is greater than in trial 2 because an inclined plane with a shallower rise will have a higher ideal mechanical advantage because less effort can be applied over a greater distance in a shallow rise than in a steep one.

2: IMA of an inclined plane does not account for things like gravity weighing an object down and friction being generated between the object and the plane, among other factors. Because both of the listed factors are things that we know will affect the object being moved up the inclined plane, we can predict that the AMA will be lower because outside factors acting on the object make the inclined plane less efficient.  

3: If a machine was 100% efficient, the IMA and AMA would be congruent. This is because for a medicine to be 100% efficient there would have to be no outside forces acting on the object. The ideal mechanical advantage does not calculate for outside forces, so with a machine having to be a place where exactly 0 outsides forces are present to be working at 100% efficiency, then common logic would say that the IMA and AMA would have to be the exact same.

 

Questions for the “answer portion of the assignment”:

According to your data, was your hypothesis correct? (Be sure to refer to your data when answering this question.)

Summarize the conclusions that you can draw from this experiment. Use the questions above to guide your ideas.

Summarize any difficulties or problems you had in performing the experiment that might have affected the results. Describe how you might change the procedure to avoid these problems.

Give at least three examples from everyday life where an inclined plane is used to reduce the effort force needed to accomplish a task.

What are two ways an object can gain more gravitational potential energy?
Ostrovityanka [42]

When an item is raised, the work is done in opposition to gravity. When an item is worked on, energy is transmitted to it, and it develops gravitational potential energy. If the same thing falls from that height, gravity must do the same amount of effort to bring it back to the Earth's surface.

Nitella [24]

Individuals suffering from somatoform disorders often see several doctors about their symptoms because doctors often refer their patients for a second opinion

<h3>What is doctors opinion?</h3>

Doctors usually ask people to take different medications to be able to treat the cause and the symptoms of a disease.

For example, they might prescribe antibiotics to treat the infection and  anti-inflammatory medication for the swelling and pain.

According to this, the statement that says that doctors often advise a combination of treatments to eradicate an infection and treat symptoms is true.

Hence Individuals suffering from somatoform disorders often see several doctors about their symptoms because doctors often refer their patients for a second opinion

Which actions are evidence that a chemical reaction has occurred? Check all that apply. a change in color the formation of a pre
NeTakaya

Answer:

  1. a change in color
  2. the formation of a precipitate
  3. the formation of bubbles

Explanation:

In a chemical reaction, there is always a rearrangement of atoms within the molecules of reactants to form new products. Such a change is different from changes in the physical form of molecules, e.g. shape.

Thus, according to this criteria, only three options are correct in the given question. A change in color is definitely an indication of chemical reaction because the emission of light before and after cannot be changed unless molecules are rearranged to form a new chemical. Likewise, precipitates form when a reaction takes place between chemically dissolved molecules to form less or not dissolvable compounds. In the end, the configuration of bubbles also indicates that the reaction has taken place because new gases are being released.

On the other hand, change in shape is a physical change because the composition doesn't need to also been changed. An example is the ice formation from water. Same is the case with "change of clear liquid to cloudy" because the addition of non-reactive substances could change the nature of liquid to cloudy however the reaction doesn't need to have taken place.
