Which scale is use for absolute zero? Absolute zero, temperature at which a thermodynamic system has the lowest energy. It corresponds to −273.15 °C on the Celsius temperature scale and to −459.67 °F on the Fahrenheit temperature scale. Does ratio have a true zero? While interval and ratio data can both be categorized, ranked, and […]
How do you classify archaea?
How do you classify archaea? Archaea, (domain Archaea), any of a group of single-celled prokaryotic organisms (that is, organisms whose cells lack a defined nucleus) that have distinct molecular characteristics separating them from bacteria (the other, more prominent group of prokaryotes) as well as from eukaryotes (organisms, including plants and … What two groups does […]
What is the effective resistance between A and D?
What is the effective resistance between A and D? D=5Ω+10Ω+5Ω=20Ω What is the effective resistance in the given circuit? The effective resistance of a circuit containing resistances in parallel is smaller than any of the individual resistances. For example : R1=2Ω and R2=3Ω ∴ Effective resistance Rp1=R11+R21. Maximum effective resistance will be when all the […]
What is the reliability of a source?
What is the reliability of a source? A reliable source is one that provides a thorough, well-reasoned theory, argument, discussion, etc. based on strong evidence. Scholarly, peer-reviewed articles or books -written by researchers for students and researchers. Original research, extensive bibliography. Why is it important to evaluate sources? Evaluating information encourages you to think critically […]
Why is the sodium potassium pump so important to the human body?
Why is the sodium potassium pump so important to the human body? In the kidneys the Na-K pump helps to maintain sodium and potassium balance in our body. It also plays a key role in maintaining blood pressure and controls cardiac contractions. What human body system depends on the sodium potassium pump? nervous system Why […]
Why must I forgive?
Why must I forgive? Forgiveness is for our own growth and happiness. When we hold on to hurt, pain, resentment, and anger it harms us far more than it harms the offender. Forgiveness frees us to live in the present. Our anger, regret, hatred, or resentment towards someone means that we are giving up our […]
When the moon passes between Earth and the sun it casts a shadow on?
When the moon passes between Earth and the sun it casts a shadow on? When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. When Earth passes directly between Sun and Moon, its shadow creates a lunar eclipse. Lunar eclipses can only happen when the Moon […]
Why does electronegativity increase as you go across a period?
Why does electronegativity increase as you go across a period? It is no wonder the electron pair gets dragged so far towards the chlorine that ions are formed. Electronegativity increases across a period because the number of charges on the nucleus increases. That attracts the bonding pair of electrons more strongly. How does electronegativity vary […]
What is the half-life of AU 198?
What is the half-life of AU 198? 2.697 days How do you calculate the half-life of sodium 24? Notice that the time period between each of the yellow crosses is 15 hours. This tells us that the count rate of Sodium-24 halves every 15 hours. In other words, the activity of Sodium-24 is halved every […]
What are three lung diseases that can be caused by air pollution?
What are three lung diseases that can be caused by air pollution? Air pollution is the cause and aggravating factor of many respiratory diseases like chronic obstructive pulmonary disease (COPD) (11,12), asthma (12,13), and lung cancer (14,15). Who is most affected by air pollution? The groups most affected by air pollution are people of color, […]
