How do you calculate water current? To calculate the water flow (in m3/s) multiply the average water velocity by the average cross-section. To express this water flow in litres per second (l/s), multiply the result (in m3/s) by 1000. 0.486 m3/s x 1 000 = 486 l/s. What is the speed in still water? Still […]
What is the velocity of star?
What is the velocity of star? In the Milky Way, stars usually have velocities on the order of 100 km/s, whereas hypervelocity stars typically have velocities on the order of 1000 km/s. Most of these fast-moving stars are thought to be produced near the center of the Milky Way, where there is a larger population […]
Why is rose quartz so powerful?
Why is rose quartz so powerful? “As a necklace, rose quartz is especially powerful because it’s worn close to the heart and heart chakra. This enables the heart center to open and release any tensions or stresses held there,” Birch claims. How long does it take to form rose quartz? Mine were formed in about […]
What are the three key components of Paraverbal communication?
What are the three key components of Paraverbal communication? Paraverbal communication has 3 key components, which are broken out below. Pitch. Pitch is how high or low your voice goes. Speed or cadence. Cadence is how fast or slow you talk. Tone. This is a combination of factors that set or convey meaning. What are […]
Which Cannot be separated physically?
Which Cannot be separated physically? What is a Pure Substance? It is something which cannot be divided into parts by physical means, as it’s all made up of the same thing. Pure substances are either elements or compounds. Elements can NOT be separated into other types of matter (physically or chemically). What are the examples […]
What is the relationship between half-life and decay constant?
What is the relationship between half-life and decay constant? This shows that the population decays exponentially at a rate that depends on the decay constant. The time required for half of the original population of radioactive atoms to decay is called the half-life. The relationship between the half-life, T1/2, and the decay constant is given […]
Why is there a difference between Celsius and Fahrenheit?
Why is there a difference between Celsius and Fahrenheit? Celsius scale, or centigrade scale, is a temperature scale that is based on the freezing point of water at 0°C and the boiling point of water at 100°C. Fahrenheit scale is a temperature scale that is based on the freezing point of water at 32°F and […]
Is MRSA hard to get rid of?
Is MRSA hard to get rid of? MRSA is resistant to many antibiotics so it can be difficult to treat. However, there are antibiotics that can treat MRSA and make the infection go away. Your doctor may culture your infection and have the lab test the bacteria to find out which antibiotic is best for […]
How do you interpret a chi square test?
How do you interpret a chi square test? For a Chi-square test, a p-value that is less than or equal to your significance level indicates there is sufficient evidence to conclude that the observed distribution is not the same as the expected distribution. You can conclude that a relationship exists between the categorical variables. What […]
Does oxygen follow octet rule?
Does oxygen follow octet rule? Octet rule: The concept that compounds containing carbon, nitrogen, oxygen, and fluorine are more stable if these atoms have eight valence electrons. When one of these atoms has less than eight valence electrons it has an open octet. Every carbon, nitrogen, oxygen, and fluorine atom in this molecule has a […]
