Explanation:
Answer:
The period is 0.628s
Explanation:
As the system mass-spring is in simple harmonic motion, the period is given by the equation:
where m is the mass of 2kg and k is the spring constant
Replacing the values in the equation, we have:
And finally we find the value of the period, that is:
Answer:
Answer is D
Explanation:
a and b have ignorance so we cancel them ,c has no knowledge so it's wrong and the remaining is D so D I the correct answer
Answer:
Randomized Control Trial (RCT)
Explanation:
A Randomized Control Trial (RCT) study is a type of scientific study method, especially used in medical studies, where the subjects of the study are randomly assigned to two groups (Test and control groups). The test groups receive a medical intervention whose effect is to be studied, while the control group receives a placebo (a substance that is inert and has no therapeutic value). Notably in this study design is that apart from the medical intervention of interest, every other variable such as age, sex, race, etc. is controlled (the same across all the groups), to reduce the occurrence of biases, and this is to ensure that the difference in the outcomes between the test and control groups are as a result of the variable of interest alone. Randomization is also critical because it helps reduce recruitment bias and mimics natural occurrence as much as possible.
