Why does the mass change? The mass of an object does not change with speed; it changes only if we cut off or add a piece to the object. Since mass doesn’t change, when the kinetic energy of an object changes, its speed must be changing. Special Relativity (one of Einstein’s 1905 theories) deals with […]
What is the effect of the Gulf Stream of Europe?
What is the effect of the Gulf Stream of Europe? Since the Gulf Stream also extends toward Europe, it warms western European countries as well. In fact, England is about the same distance from the equator as cold regions of Canada, yet England enjoys a much warmer climate. If it weren’t for the warm water […]
Which amino acid is involved in the formation of disulfide bonds?
Which amino acid is involved in the formation of disulfide bonds? The cysteine amino acid group is the only amino acid capable of forming disulfide bonds, and thus can only do so with other cysteine groups. What two functional groups are found in amino acids? Carboxyl and amino groups are always found in amino acids. […]
Where is the thickest loess deposits found?
Where is the thickest loess deposits found? Extensive loess deposits are found in northern China, the Great Plains of North America, central Europe, and parts of Russia and Kazakhstan. The thickest loess deposits are near the Missouri River in the U.S. state of Iowa and along the Yellow River in China. Is Loess erosional or […]
Can you capture an image formed by a convex mirror on a screen?
Can you capture an image formed by a convex mirror on a screen? Why it is not possible to capture an image formed by convex mirror ? A convex mirror, also known as a diverging mirror, as this mirror diverges light when they strike its reflecting surface. It always forms virtual, erect, and diminished images […]
What is the Doppler effect and why is it important?
What is the Doppler effect and why is it important? The Doppler effect is important in astronomy because it enables the velocity of light-emitting objects in space, such as stars or galaxies, to be worked out. What are two everyday applications of the Doppler effect? The Doppler effect has several real-world applications. For example, besides […]
Is gravitational force equal to weight?
Is gravitational force equal to weight? The gravitational force on Earth is equal to the force the Earth exerts on you. At rest, on or near the surface of the Earth, the gravitational force equals your weight. What two factors does gravitational force depend on? When dealing with the force of gravity between two objects, […]

Skip the tray in the lunch line and use only one plate. Turn off the water when washing your hands. Report leaks to the appropriate authorities. In labs and […]
What is LS coupling explain with example?
What is LS coupling explain with example? The energy levels which are characterised by certain values of L and S are called terms and the coupling of angular momenta of individual electrons to a resulting orbital angular momentum and spin is referred to as LS-coupling or Russell-Saunders coupling. Which is the selection role for LS […]
Why does a hollow sphere have more rotational kinetic energy?
Why does a hollow sphere have more rotational kinetic energy? Another hollow sphere of the same mass and radius is rotating about its axis through the center at the same rotation rate. Which sphere has a greater rotational kinetic energy? The hollow sphere, since the mass is distributed further away from the rotation axis. Does […]
