You used three methods of analysis to find the acceleration of the cart on the track: a two-point difference from v(t), an average of a(t) that was itself calculated by a succession of first differences of the v(t) data, and a line fit to v(t). some criteria to help you consider which method is best are part a in which type of graph(s) is it easiest to see whether the acceleration was constant?

[ad_1]

Answered by answersmine AT 22/10/2019 – 02:29 AM

The best way to find that you want is the line fit. When acceleration is constant the speed(v) changes smoothly every moment, so the v line must be straight. Differently, the accelaration changes.

1. The answer is “C”.

“Identical twins” who have been raised apart are typically more similar in intelligence level than biological siblings raised together because they have been born with the same genetic code.

Identical twins originate from a single fertilized egg that parts into two. Before it parts, it is either male or female. After it parts, there are either two guys or two females. The two sections of the fertilized egg embed in the uterus and every create one of the twins.  

Identical twins have the equivalent hereditary source. No immediate reason for monozygotic twinning has been resolved; it isn’t innate. Monozygotic twins speak to around 33% all things considered. They may look strikingly comparative, and it might be hard to reveal to them separated.

2. The answer is “A”.

Lawrence Kohlberg felt that one of the only ways individuals will accomplish the objectives in each of his six stages was to participate in “consensus democracy” in small group settings.

Lawrence Kohlberg felt that the best way to support development through these stages was by discourse of good problems and by investment in consensus democracy inside small groups. Consensus democracy was rule by understanding of the gathering, not larger part rule. This would invigorate and widen the reasoning of youngsters and grown-ups, enabling them to advance starting with one phase then onto the next.

3. The answer is “D.  showing a learner how to correct common mistakes”.

The term scaffolding alludes to a procedure in which instructors display or exhibit how to take care of an issue, and afterward venture back, offering support as required. Analyst and instructional architect Jerome Bruner first utilized the term ‘scaffolding’ in this setting, harking back to the 1960s. The hypothesis is that when understudies are given the help they require while discovering some new information, they stand a superior possibility of utilizing that learning freely. Bruner suggests positive association and three methods of portrayal amid educating: activities, pictures, and dialect.

Answer:

1) Water has very high specific heat.

2) It expands when it freezes

3) ability to dissolve in ionic substances

4) Water molecules at the surface experience fewer hydrogen bonds than water molecules within the liquid.

Explanation:

1) Water molecules due to their high specific heat , undergo relatively less increase in temperature after absorbing heat. So they prevent their adjoining area to experience sharp increase in temperature.

2) Water is an example which expands on freezing. In it , large spaces are left between molecules when it cools. It happens because hydrogen bonds prevent any two molecules to come very close thereby  creating gaps. This gap is filled up when ice melts , which results in overall reduction in volume of water.

3) Uneven distribution of charge results in water molecules becoming polar in nature . A polar substance  can be dissolved in polar solvents only.

4) It is due to property of surface tension. Property  of surface tension results due to molecules of water near the surface experiencing a  net downward  force due to hydrogen bonds . It is due to fewer hydrogen bonds made by them.

Well; You have the classics

1984, you might have been asked to read this one already in school, if not I suggest going ahead and reading it; its fun to be ahead of your class. 

Originally published in 1949 by George Orwell, 1984 depicts a dystopian world of the ‘future’. The book is less of a prediction more then it is a warning of what could be. It follows one character who is desperately trying to remember what real life is like, and gets tangled up in all sorts of messes along the way.

You could read Alice in Wonderland or Mary Poppins, theres a million great classics out there Im sure you can find on any website. 

Personally I prefer fantasy novels; 

Brandon Sanderson’s The Rithmatist 
This book follows a young student through a steampunk style, magic infused world. It takes a moment to not chuckle at the concept of monsters that are essentially drawings, but its a very well done book with beautiful writing and mental scenery 

Patrick Rothfuss’s, The Name of the Wind 
This is my favorite book of all time. Patrick Rothfuss’s work is honestly amazing in this book. Mind you its probably not all that wise for the feint of heart through perhaps the second chapter; but it really is amazing. The sculpting of the world, the depth of the characters its utterly masterful. The story opens with Kote, a fairly normal seeming innkeeper and his dark haired companion Bast. Fairly normal until a man happens upon the inn, looking for a certain Kvothe, a man thought to just be a legend and a story… and Kote’s past is drug up, and other things that should probably be better left alone.

The basis to respond this question are:

1) Perpedicular lines form a 90° angle between them.

2) The product of the slopes of two any perpendicular lines is – 1.

So, from that basic knowledge you can analyze each option:

a.Lines s and t have slopes that are opposite reciprocals.

TRUE. Tha comes the number 2 basic condition for the perpendicular lines.

slope_1 * slope_2 = – 1 => slope_1 = – 1 / slope_2, which is what opposite reciprocals means.

b.Lines s and t have the same slope.

FALSE. We have already stated the the slopes are opposite reciprocals.

c.The product of the slopes of s and t is equal to -1

TRUE: that is one of the basic statements that you need to know and handle.

d.The lines have the same steepness.

FALSE: the slope is a measure of steepness, so they have different steepness.

e.The lines have different y intercepts.

FALSE: the y intercepts may be equal or different. For example y = x + 2 and y = -x + 2 are perpendicular and both have the same y intercept, 2.

f.The lines never intersect.

FALSE: perpendicular lines always intersept (in a 90° angle).

g.The intersection of s and t forms right angle.

TRUE: right angle = 90°.

h.If the slope of s is 6, the slope of t is -6

FALSE. – 6 is not the opposite reciprocal of 6. The opposite reciprocal of 6 is – 1/6.

So, the right choices are a, c and g.

The goals of psychology are to a. develop effective methods of psychotherapy and cure mental illness. b. describe, understand, predict, and control behavior. c. research, infer, summarize, and publish. d. compare, analyze, and control human behavior.

[ad_1]

Answer:

The answer is C. In order to carefully control conditions and confirm or disconfirm a hypothesis about the causes of behavior, one must perform an experiment.

Explanation:

Experimental research allows the researcher to control all the variables in order to create the conditions that can confirm or disconfirm a hypothesis. This method aimes to establish a relation of causality between two variables, which means that one variable is generated and determined by the other; this is posible because all of the other variables that can influence it have been controlled.

When a researcher conducts a survey or engages in naturalistic observation, he can’t control the variables, therefore, he can only establish a correlation between two variables, but not of causality.

[ad_1]

The Emancipation Proclamation, formally issued on January 1, 1863, by
President abraham lincoln is often mistakenly praised as the legal
instrument that ended slavery—actually, the thirteenth amendment to the
Constitution, ratified in December 1865, outlawed slavery. But the
proclamation is justifiably celebrated as a significant step toward the
goal of ending slavery and making African Americans equal citizens of
the United States. Coming as it did in the midst of the Civil War
(1861–65), the proclamation announced to the Confederacy and the world
that the abolition of slavery had become an important goal of the North
in its fight against the rebellious states of the South. The document
also marked a shift in Lincoln’s mind toward support for emancipation.
Just before signing the final document in 1863, Lincoln said, “I never,
in my life, felt more certain that I was doing right than I do in
signing this paper.”

In the text of the proclamation—which is
almost entirely the work of Lincoln himself—Lincoln characterizes his
order as “an act of justice, warranted by the Constitution upon military
necessity.” These words capture the essential character of Lincoln’s
work in the document. On the one hand, he perceived the proclamation as a
kind of military tactic that would aid the Union in its difficult
struggle against the Confederacy. As such, it was an extraordinary
measure that carried the force of law under the powers granted by the
Constitution to the president as commander in chief of the U.S. military
forces. But on the other hand, Lincoln saw the proclamation as “an act
of justice” that announced the intention of the North to free the
slaves. In this respect, it became an important statement of the intent
to abolish slavery in the United States once and for all, as well as a
vital symbol of human freedom to later generations.

Answer:

The midpoint of line segment is (5,9).

Step-by-step explanation:

Given : Line segment whose endpoints are (3, 10) and (7, 8).

To find : Find the midpoint of the line segment .

Solution : We have given that endpoints  (3, 10) and (7, 8).

By the midpoint segment formula :

     Midpoint :

(frac{x_{1}+x_{2}}{2} , frac{y_{1}+y_{2}}{2}).

Here, the coordinate of x_{1} = 3 ,   x_{2} = 7 ,

                                      y_{1} = 10 ,      y_{2} = 8 ,

Plugging values in formula ,

Midpoint =(frac{3+7}{2} , frac{10+8}{2}).

Midpoint =(frac{10}{2} , frac{18}{2}).

Midpoint = (5 , 9).

Therefore, the midpoint of line segment is (5,9).
