Design a posttest-only experiment that would test each of the following causal claims. For each one, identify the study’s indepe

ndent variable(s), identify its dependent variable(s), and suggest some important control variables. For each study, determine a survey that you might administer that would give the research additional information on individual personality differences. a. Students given negative (versus positive) feedback on an important value they possess causes individuals to act more aggressively. b. Exercising for 30 minutes a day (compared with 10 minutes a day) causes less depression. c. Exposing individuals to messages that ones peers engage in environmental friendly behaviors (versus receiving an informational flyer about the importance of the environment) leads to increases in environmental friendly behaviors.

Answer:

a.

Here independent variable is negative reinforcement like punishment. The dependent variable is aggressiveness.

Control group : Teacher

Experiment group : Students

b.

Independent variable : Exercise

Dependent variable : Depression

Various levels of independent variables : The time of exercise may be increased or reduced

c.

Independent variable: Environment friendly messages

Dependent variables : Environment friendly behavior

Interaction: The verbal exchange among the peers.

Create a separate function file fieldtovar.m that receives a single structure as an input and assigns each of the field values t
Soloha48 [4]

Answer:

Explanation gives the answer

Explanation:

% Using MATLAB,

% Matlab file : fieldtovar.m

function varargout = fieldtovar(S)

% function that accepts single structure as input, assigning each

% of the field values to user-defined variables

fields = fieldnames(S); % get the field names of the input structure

% check if number of user-defined variables and number of fields in

% structure are equal

if nargout == length(fields)

% if equal assign each value of structure to user-defined varable

for i=1:nargout

varargout{i} = getfield(S,fields{i});

end

else

% if not equal display an error message

error('The number of output variables does not equal the number of fields');

end

end

%This brings an end to the program

A train consists of a 50 Mg engine and three cars, each having a mass of 30 Mg . If it takes 75 s for the train to increase its
ohaa [14]

Answer:

T = 15 kN

F = 23.33 kN

Explanation:

Given the data in the question,

We apply the impulse momentum principle on the total system,

mv₁ + ∑\int\limits^{t2}_{t1} {Fx} \, dt = mv₂

we substitute

[50 + 3(30)]×10³ × 0 + FΔt = [50 + 3(30)]×10³ ×  ( 45 × 1000 / 3600 )  

F( 75 - 0 ) =  1.75 × 10⁶

The resultant frictional tractive force F is will then be;

F =  1.75 × 10⁶ / 75

F = 23333.33 N

F = 23.33 kN

Applying the impulse momentum principle on the three cars;

mv₁ + ∑\int\limits^{t2}_{t1} {Fx} \, dt = mv₂

[3(30)]×10³ × 0 + FΔt = [3(30)]×10³ ×  ( 45 × 1000 / 3600 )  

F(75-0) = 1.125 × 10⁶

The force T developed is then;

T =  1.125 × 10⁶ / 75

T = 15000 N

T = 15 kN
