Answer:
How does the drink content affect an individual's blood pressure?
Explanation:
In every experiment using the scientific method, an observation lays the foundation of that experiment. A problem must be observed, which then leads to asking a SCIENTIFIC QUESTION in order to investigate. A scientific question must include the variable being changed called INDEPENDENT VARIABLE and the variable being measured called DEPENDENT VARIABLE.
In this experimental procedure or set up,
- Group 1 drinks 500 mL of coffee a day.
- Group 2 drink 500 mL of tea a day,
- Group 3 is a control group i.e no drink
At the end of 60 days all participants
blood pressure is tested.
This set up indicates that the variable being changed (independent) is the DRINK CONTENT while the variable being measured (dependent) is the BLOOD PRESSURE. Hence, these variables serve as the template to ask a scientific question which goes thus:
HOW DOES THE DRINK CONTENT AFFECT AN INDIVIDUAL'S BLOOD PRESSURE?
This scientific question relates how the independent variable (drink) causes the dependent variable to respond (blood pressure).
Answer:
m=ρV
V=LxWxD
V=4x10x2=80
m=2*80=160 grams
Explanation:
Mass is equal to density multiply by volume of object. Volume of rectangle pice can be calculated by multiplying all sides.
Well if the boat initially at rest accelerates at uniformly at 4.0 m/s (squared) then it would be best to muitlply it so 4.0 squared equals 2 by multiplying that by 7.0 your answer would be 14 s
A. Moving with constant non-zero speed
Perfect
symmetrical cone type volcanoes would have radial drainage pattern.
A stratovolcano, also known as a composite volcano, is a
conical volcano built up by many layers (strata) of hardened lava, tephra,
pumice, and volcanic ash.
