How does gradient change discharge? While gradient decreases between a stream’s headwaters and mouth, discharge increases. Gradient and discharge determine the velocity of a stream. What is a stream profile? A stream profile is a cross-section view of a stream from its headwaters to its mouth. What is the relationship between urbanization and water supply? […]

What month do geese fly south? Late spring or early summer is typically when you’ll notice geese flying north in that famous V pattern (which they use to save energy as it reduces wind drag on the geese not at the tip of the V). September and early November is typically when geese begin flying […]

Can you fly through a tornado? Flying through a tornado could destroy an airplane; pilots avoid all thunderstorms — particularly those producing tornadoes — by a wide margin. Is a tornado more dangerous than a hurricane? While both types of storms are capable of producing destructive winds, tornadoes can become stronger than hurricanes. The most […]

What is the CMS system? A Content Management System, or CMS, is a piece of software designed to help users create and edit a website. They have evolved to help design the look of websites, track user sessions, handle searches, collect visitor comments, host forums and much much more. What is CMS LHC? The Compact […]

Is it possible for a car to move at constant speed and be accelerating? The velocity vector is constant in magnitude but changing in direction. For this reason, it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating. It is accelerating because the direction of the velocity […]

What is another name for an interneuron? Interneurons (also called internuncial neurons, relay neurons, association neurons, connector neurons, intermediate neurons or local circuit neurons) are neurons that connect two brain regions, i.e. not direct motor neurons or sensory neurons. What is an example of a interneuron? The nerve cells of the central nervous system are […]

Which mineral test is shown in the image 2 points image showing minerals that have been rubbed against a white board leaving different colored lines on the board? Streak test is a method to determine what color would the mineral had if it’s being transformed into a powdered form. This test is being done by […]

Why did the ball roll when laid on the floor? because the friction present between the surface pushes the atoms/particles in contact with surface or ground backwards, hence with centre of mass moving in a direction, the ball’s bottom surface(ie. The surface in contact) moves in opposite direction or backwards, causing the ball to roll. […]

Which is more elastic glass or steel? The Coefficient of elasticity of glass is between 50 and 90; the Coefficient of elasticity of steel is 210; the Coefficient of elasticity of Copper is 120. Therefore, the rubber is more elastic than glass and glass is more elastic than copper and copper is more elastic than […]

Does the direction of EMF depend on direction of current? Direction of EMF is decided by the construction of the battery cell, it does not depend upon the direction of the current flow. In fact direction of the current flow depends upon the direction of emf. However direction of the voltage drop depends upon the […]
