During a test trial, the control and test group are both given a pill. To account for the effect patients may think the drug being tested is having just because they believe they're being treated, the control group is given a "sugar pill," which is called what?A) Placebo

D) Screening Tool 
Ohp xD nvm, the answer is A !

Answers

During the test trial, the sugar pill given to the control group is called a  placebo. Therefore, the correct option is A. Placebo

What is a placebo ?

A placebo is any drug or a treatment with no active substances, for example a sugar pill.

During clinical trials, usually one group takes the actual drug while the other group takes the placebo without being aware of it.

Placebo is an inactive treatment given to a group of people that is made to look like the real drug, but in reality it simply makes the patient believe they're being treated with the drug and that the drug will help them relieve from the symptoms.

By comparing the results from the two groups, this method helps in analyzing the accurate effects of the drug on the patients and helps in proving that it was the drug that actually treated the symptom and that the treatment did not occur by chance or just a mere belief of the patient thinking they will get better because they're being treated.

This approach helps reduce bias and ensures that the trial's results are more accurate and reliable.    

So, the sugar pill given to the control group is called a  placebo. Therefore, the correct option is A. Placebo

Which statement is true because of newtons second law ?a)when the net force on an object increases, the objects acceleration decreases
b)when the net force on an object decreases ,the objects acceleration increases
c)when the net force on an object decreases, the acceleration doesnt change
d)when the net force on an object decreases, the objects acceleration decreases

Answers

Newton's second law, by definition, states that,  The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. Therefore, based on the given options above, the correct answer would be option D: when the net force on an object decreases, the objects acceleration decreases.

d. when the net force on an object decreases, the objects acceleration decreases
