Is differential equations the hardest math class? Even though there are some aspects of differential equations that can be difficult, overall, I would say that differential equations are actually one of the easier higher level math classes. In addition, differential equations do not tend to be as proof heavy as other higher level math classes. […]

What is the similarities of divergent and convergent? The similarities are that a boundary of any kind marks the line between two tectonic plates. Similarities between divergent and convergent boundaries include magma or lava flows, formation of new topographic features and re-shaping of landmasses. What are the similarities and differences between convergent and divergent boundaries? […]

What are the gateway drugs and why are they called as such? A gateway drug is a term that is commonly used in reference to particular substances that are thought to open the way to using more dangerous or harder drugs such as heroin or cocaine. What does gateway drug mean? The definition of a […]

What are core drill bits? Core drill bits are designed to cut large holes in dense materials, like masonry, brick and stone, and remove a core of debris. They feature large notched teeth that cut cleanly and precisely. What is a coring bit used for? A core bit (Fig. 1, Fig. 2) is a drilling […]

Why is my car making a whining noise when I drive? If you hear a whining noise from your car’s engine, it may mean much the same thing: there’s a component that’s worn out. If these parts break or wear down entirely, they could cause damage, so hearing a whining sound means that it’s time […]

Why is my breadmaker bread so dense? Dense bread is the result of four possible agents: dead yeast due to water heat, not enough or damaged gluten, insufficient kneading or inadequate rising time. For bread made in a bread machine, the programs are set to mix, knead, rise and bake according to the selected recipe. […]

What is called battery? A battery is a device that converts chemical energy contained within its active materials directly into electric energy by means of an electrochemical oxidation-reduction (redox) reaction. This type of reaction involves the transfer of electrons from one material to another via an electric circuit. What is the symbol of battery? Cells […]

What is the EU migration policy? Migration policy of the European Union – is a set of principles and measures used by member countries of the European Union aimed to regulate migration processes in the EU zone. How is migration managed within the EU? They set out the rules for returning people residing illegally in […]

What produces a reverse fault? Reverse faults are exactly the opposite of normal faults. If the hanging wall rises relative to the footwall, you have a reverse fault. Reverse faults occur in areas undergoing compression (squishing). How do faults affect Earth’s surface? Earthquakes occur on faults. A fault is a thin zone of crushed rock […]

What is shear strain equal to? Shear strain is defined by the ratio of the largest displacement Δx to the transverse distance L0. shear strain=ΔxL0. shear strain = Δ x L 0 . Shear strain is caused by shear stress. Shear stress is due to forces that act parallel to the surface. What is shear […]
