Is High Altitude good for high blood pressure? The available evidence suggests blood pressure rises to a modest extent in patients with mild to moderate hypertension upon acute ascent to high altitude, but there is no clear evidence of an increased risk of complications due to these increased pressures. Is High Altitude better for health? […]
What is an example of zero correlation?
What is an example of zero correlation? A zero correlation exists when there is no relationship between two variables. For example there is no relationship between the amount of tea drunk and level of intelligence. What does a correlation of indicate? A correlation is a statistical measurement of the relationship between two variables. A zero […]
How can Archimedes Principle predict if something will float?
How can Archimedes Principle predict if something will float? An object will float if the buoyancy force exerted on it by the fluid balances its weight, i.e. if FB=mg F B = mg . But the Archimedes principle states that the buoyant force is the weight of the fluid displaced. So, for a floating object […]
What is the displacement of the object during acceleration?
What is the displacement of the object during acceleration? Displacement equals the original velocity multiplied by time plus one half the acceleration multiplied by the square of time. Here is a sample problem and its solution showing the use of this equation: An object is moving with a velocity of 5.0 m/s. What is a […]
What does it mean when chromosomes condense?
What does it mean when chromosomes condense? Chromosome condensation is the dramatic reorganisation of the long thin chromatin strands into compact short chromosomes that occurs in mitosis and meiosis. At which phase of mitosis do the sister chromatids become daughter chromosomes? anaphase During which phase of mitosis do the chromatids become chromosomes quizlet? During which […]
What are the methods of data interpretation?
What are the methods of data interpretation? In this part, we will look at the two main methods of interpretation of data: with a qualitative and a quantitative analysis….Other signature interpretation processes of quantitative data include: Regression analysis. Cohort analysis. Predictive and prescriptive analysis. How many types of data analyst are there? four What are […]
Is current density scalar or vector?
Is current density scalar or vector? Despite being the ratio of two scalar quantities, current density is a vector. And the reason is, because it is. Well… actually, it’s because current density is defined as the product of charge density and velocity for any location in space… Is electricity a vector quantity? Vector of scalar? […]
What are the three properties of density?
What are the three properties of density? General Properties of Density Mass of the Object. The mass of the object being measured for density is a part of the calculation. Volume. Volume also decides the final density value. The Calculation. Putting volume and mass together in a calculation defines density. Water. When objects are measured […]
How do humans do photosynthesis?
How do humans do photosynthesis? Human photosynthesis doesn’t exist; we must farm, slaughter, cook, chew and digest — efforts that require time and calories to accomplish. As the human population grows, so does the demand for agricultural goods. Not only are our bodies expending energy, but so are the farm machines we use to make […]
