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.
Answer:
option a is correct answer i.e. d = 1.6 mm
Explanation:
From conservation principle
force by jet = force required to hold the jet
force by the jet is written as
force required to hold the jet = 8N
we know that mass flow rate is given as
substituting value to get required diameter of the nozzle
d = 1.6 mm
Answer: The engineering design process emphasizes open-ended problem solving and encourages students to learn from failure. This process nurtures students abilities to create innovative solutions to challenges in any subject! In addition to their involvement in design and development, many engineers work in testing, production, or maintenance. These engineers supervise production in factories, determine the causes of a component's failure, and test manufactured products to maintain quality.
