How do you know if correlation is positive or negative? We often see patterns or relationships in scatterplots. When the y variable tends to increase as the x variable increases, we say there is a positive correlation between the variables. When the y variable tends to decrease as the x variable increases, we say there […]

What is the direction of a friction force?
What is the direction of a friction force? The frictional force is the other component; it is in a direction parallel to the plane of the interface between objects. Friction always acts to oppose any relative motion between surfaces. Do we walk due to friction? When you are walking, static friction pushes in the direction […]
What is the use of reverse bias?
What is the use of reverse bias? A reverse bias reinforces the potential barrier and impedes the flow of charge carriers. In contrast, a forward bias weakens the potential barrier, thus allowing current to flow more easily across the junction. What happens in reverse bias? By applying a negative voltage (reverse bias) results in the […]
Will clogged ear go away by itself?
Will clogged ear go away by itself? A clogged ear is usually temporary, with many people successfully self-treating with home remedies and OTC medications. Contact your doctor if your ears remain blocked after experimenting with different home remedies, especially if you have hearing loss, ringing in the ears, or pain. How long does a blocked […]

What is an example of a positive feedback loop?
What is an example of a positive feedback loop? Positive feedback occurs to increase the change or output: the result of a reaction is amplified to make it occur more quickly. Some examples of positive feedback are contractions in child birth and the ripening of fruit; negative feedback examples include the regulation of blood glucose […]
Are there 5 or 6 kingdoms?
Are there 5 or 6 kingdoms? Until recently the system devised by Robert Whittaker in 1968 was widely adopted. Whittaker’s classification scheme recognizes five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia. What are the 3 main domains of life? According to this system, the tree of life consists of three domains: Archaea, Bacteria, and Eukarya. […]
Do we have 3 moons?
Do we have 3 moons? After more than half a century of speculation, it has now been confirmed that Earth has two dust ‘moons’ orbiting it which are nine times wider than our planet. Scientists discovered two extra moons of Earth apart from the one we have known for so long. Earth doesn’t have just […]
What is the range of energies for secondary electrons?
What is the range of energies for secondary electrons? Secondary electrons are generally considered to have energies below 50 eV. The rate of energy loss for electron scattering is very low, so most electrons released have energies peaking below 5 eV(Seiler, 1983). How secondary electrons are formed? Secondary electrons (SE) are produced when an incident […]
