<span>Adults in a family control the money, much as the wealthy control capital in the larger economy as a whole. The children are dependent upon them, just as workers are dependent upon capitalists to provide jobs through investment.</span>
In this question, there are several information's that can be used to determine the right answer.Let us first check all the information's that have been provided in the question.
Initial velocity = 25 m/s
Final velocity = 0 m/s
Initial time = 0 second
Final time = 5 second
Now we can write an equation to determine the acceleration.
Acceleration of the object = (Final velocity - Initial velocity)/ (Final time - Initial time)
= (0 - 25)/ (5 - 0)
= - 25/5
= -5 m/s^2
So we find the acceleration of the object as -5m/s^2. the correct option among the given options in the question is option "A".
The primary concern of the scientist in clinical trial is patient safety.
A clinical trial is one of the final stages of any research process according to the requirement. Studies are done to find if the approach of the research and treatment is effective.
Clinical test or trial on human beings is done only after the pre-clinical phase which involves laboratory studies on animals (in vitro) to check the safety and efficiency of the drug. Animals are quite different from humans so human clinical trials are required to be done.
The main aim of clinical trial involves three major things to be considered: if the drug is working, the efficiency of the drug as compared to the currently present drug and most importantly that the drug is safe for human use and the patient is safe after the administration of the drug into the body.
Answer:
2. 2H2O2 -> 2H2O+ O2
Explanation:
This equation is balanced because there are equal amounts of each element on each side. 4 Hydrogen on the left, 4 On the Right. 4 Oxygen on the Left, 4 on the right.
Although 1 is balanced it is not the Chemical equation for hydrogen peroxide (H2O2)
2. is not the equation for Hydrogen Peroxide
4. Balanced although this one does not show oxygen as a gas ( when oxygen is a gas it is O2)
