What is phase difference measured in? Phase difference: The time interval by which a wave leads by or lags by another wave is called “Phase difference” or “Phase angle”. It is defined by ‘Φ’. The phase angle is measured in “Radians / Sec” or “Degrees / Sec” and the phase of a complete cycle is […]
Which of the following is an assumption of the molecular clock?
Which of the following is an assumption of the molecular clock? The “molecular clock” method assumes that changes in DNA accumulate at approximately constant rates over time. One explanation is that species might undergo genetic changes long before those changes are reflected in the body plan. What does the molecular clock used to determine how […]
Why is it important to reduce energy usage?
Why is it important to reduce energy usage? First of all, reducing energy use limits the number of carbon emissions in the environment. In turn, conserving energy produces a higher quality of life. Reduced emissions result in cleaner air quality. In addition, it helps create a healthier planet, or at least helps sustain the resources […]

How do I get rid of reactive power?
How do I get rid of reactive power? Inductive reactive power can be reduced by applying a capacitor bank. With an active dynamic filter, all types of reactive power can be reduced and the derating of the transformer or generator is limited. What exactly is reactive power? Reactive Power can best be described as the […]
What is the human cause of climate change?
What is the human cause of climate change? Humans are increasingly influencing the climate and the earth’s temperature by burning fossil fuels, cutting down forests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming. What is a natural climate change? […]
What is difference between current and drift velocity?
What is difference between current and drift velocity? Current is the flow of free charges, such as electrons and ions. Drift velocity vd is the average speed at which these charges move. What is the relation between drift velocity and area? Current IenA=v where v is drift velocity , e is the charge of an […]
What group is the smallest level of classification?
What group is the smallest level of classification? Species is the smallest and least inclusive of the taxonomic categories. Kingdom, Phylum, Class, Order, Family, Genus, Species. Which is not a category? Phylum, Species, and Class are taxonomic category. But, Glumaceae is not a category. It is a botanical name assigned to order including the family […]
Which nerve carry messages from ear to brain?
Which nerve carry messages from ear to brain? The cochlear nerve, also known as the acoustic nerve, is the sensory nerve that transfers auditory information from the cochlea (auditory area of the inner ear) to the brain. How do you fix auditory nerve damage? Once damaged, your auditory nerve and cilia cannot be repaired. But, […]
How do you change the concentration of a solution?
How do you change the concentration of a solution? The concentration of a solution can be changed: concentration can be increased by dissolving more solute in a given volume of solution – this increases the mass of the solute. concentration can be increased by allowing some of the solvent to evaporate – this decreases the […]
