What do the lithosphere and asthenosphere have in common? Both the lithosphere and asthenosphere are part of Earth and are made of similar material. Lithosphere is made up of Earth’s outermost layer, the crust, and the uppermost portion of the mantle. In comparison, the asthenosphere is the upper portion of Earth’s mantle (which is also […]

Why is phrenology no longer accepted? Phrenology was mostly discredited as a scientific theory by the 1840s. This was due only in part to a growing amount of evidence against phrenology. Phrenologists had never been able to agree on the most basic mental organ numbers, going from 27 to over 40, and had difficulty locating […]

What is called electric resistance? In electronics and electromagnetism, the electrical resistance of an object is a measure of its opposition to the flow of electric current. The reciprocal quantity is electrical conductance, and is the ease with which an electric current passes. Does 240V need a neutral? A 240V load needs two “ungrounded conductors”, […]

How do you show subsets in a Venn diagram? Venn Diagrams If a set A is a subset of set B, then the circle representing set A is drawn inside the circle representing set B. If set A and set B have some elements in common, then to represent them, we draw two circles which […]

What is the darkest phase of the moon? The moment a thin sliver of the Moon becomes visible after New Moon is the beginning of the first intermediate phase, the Waxing Crescent Moon. In the past, this used to be called New Moon while the darkest phase was called Dark Moon. How long does the […]

How do you find initial kinetic energy? Kinetic Energy and Work The kinetic energy of an object is defined as 2 KE = 1/2 * m * v. The kinetic energy of an object depends on its velocity. We can this combination of force and distance work, so KE(final) – KE(initial) = Work done on […]

Did Maria Belon lose her leg in the tsunami? She lost part of a leg in the tragedy, but miraculously (spoiler alert), she managed to reunite with the rest of her family by sheer luck. More than 283,000 died. Belon, once a family doctor turned stay-at-home mom, emerged from the ordeal a different person. How […]

What are the pros and cons to oil? The process of bringing Oil to the surface for us to use is called oil drilling, this creates many Pros and Cons of Oil Energy….Pros of Oil Energy Oil Laid the Foundation for Renewable Energy. Oil is Cheap. The Oil Industry Produces Jobs. Oil Goes a Long […]

Is a survey a secondary source? Primary sources are the original documents of an event or discovery such as results of research, experiments or surveys, interviews, letters, diaries, legal documents, and scientific journal articles. diaries and letters. academic articles reporting NEW data and findings. What is secondary data analysis examples? They might search through periodicals, […]

What will happen to the pressure of a contained gas if its temperature is lowered? How does a decrease in temperature affect the pressure of a contained gas? The pressure decreases because the kinetic energy decreases with the temperature and slower moving particles impact the walls of a contain with less energy. Which three factors […]
