Please help me I really need it!!5. Read the scenarios below. For each of the scenarios, identify the following (you should iden

tify the 3 for EACH of the scenarios):Control Group Independent Variable Dependent VariableA. John thinks that a special juice will increase the productivity of workers. He creates two groups of 50 workers each and assigns each group the same task (in this case, they're supposed to staple a set of papers). Group A is given the special juice to drink while they work. Group B is not given the special juice. After an hour, John counts how many stacks of papers each group has made. Group A made 1,587 stacks, Group B made 2,113 stacks.B. Candy notices that her shower is covered in a strange green slime. Her friend Belinda tells her that coconut juice will get rid of the green slime. Candy decides to check this out by spraying half of the shower with coconut juice. She sprays the other half of the shower with water. After 3 days of "treatment" there is no change in the appearance of the green slime on either side of the shower.C. Elisa is working on a science project. Her task is to answer the question: "Does Grow Long (which is a commercial hair product) affect the speed of hair growth?" Her family is willing to volunteer for the experiment.

A) C. group: Group B, I. variable: Special juice, D. variable: Stacks of papers made. B) C. group: Half of the shower sprayed with water I. variable: coconut spray D. variable: change in green slime. C) C. group: members who do not use the product, I. variable: Grow Long use, D. variable: Speed of hair growth.

<h3>Control group</h3>

The control group is selected from the same population as the treatment group.

These two groups are identical in all aspects except for the independent variable that the researcher changes in the experimental group to observe how they affect the individuals.  

The control group is used to identify if there are any other factors influencing the results obtained by the treatment in the study, from the results that might be a consequence of other factors.

Data from an experimental group are compared with the data from a control group.

<h3>Independent Variable </h3>

Refers to all the variables that provoke a response in another variable.

An independent variable is the one that changes or is controlled and modified to analyze how another variable responds to it.

It changes to analyze its effects on the dependent variable.

<h3>Dependent Variable</h3>

The dependent variable depends on any change in the independent variable.

Its value depends on how the independent variable is modified.

The change in the dependent variable might be either proportional or inversely proportional to the change in the manipulated variable.

A) Control group: Group B, who is not given the special juice.

    Independent variable: Special juice ingestion.

    Dependent variable: Stacks of papers each group makes.

B) Control group: Half of the shower sprayed with water

    Independent variable: Coconut juice spray

    Dependent variable: change in the appearance of the green slime.

C) Control group: The members of the family that do not use the product

    Independent variable: Grow Long use

   Dependent variable: Speed of hair growth

How much energy is produced when the sun
adell [148]

Answer:

E=1.53\times 10^{17}\ J

Explanation:

We need to find the energy produced when Sun converts 1.7 kg of mass into energy. Einstein's mass energy relation is given by :

E=mc^2

c is speed of light

E=1.7\times (3\times 10^8)^2\\\\E=1.53\times 10^{17}\ J

So, energy produced is 1.53\times 10^{17}\ J.
