What path does light take? Whether it is traveling through air, water, glass, diamond, a smoky Broadway stage, or any other transparent substance (or in nothing — the vacuum of space), light travels in a straight path until it encounters a different medium. So straight that analogies fail — the path of light is the […]

Why is vibration a serious health issue? Vibration can cause changes in tendons, muscles, bones and joints, and can affect the nervous system. Collectively, these effects are known as Hand-Arm Vibration Syndrome (HAVS). Workers affected by HAVS commonly report: attacks of whitening (blanching) of one or more fingers when exposed to cold. Can anxiety make […]

Why face centered cubic exist? If the rows of atoms are packed in this third layer so that they do not lie over atoms in either the A or B layer, then the third layer is called C. This packing sequence would be designated ABCABC, and is also known as face-centered cubic (FCC). Is an […]

How do you find the angle of depression? The angle of depression may be found by using this formula: tan y = opposite/adjacent. The opposite side in this case is usually the height of the observer or height in terms of location, for example, the height of a plane in the air. The adjacent is […]

How can we make solar cells more efficient? One cost-effective way to improve efficiency is to build a tandem device made of silicon and another inexpensive photovoltaic material, he said. “Making low-cost tandems is very desirable,” McGehee said. “You simply put one solar cell on top of the other, and you get more efficiency than […]

What is the fastest that something can travel? But Einstein showed that the universe does, in fact, have a speed limit: the speed of light in a vacuum (that is, empty space). Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second). Who is the weakest Hokage? Kakashi Hatake Who is the […]

Why do we say motion is relative in nature? all motions are relative to some frame of reference. When we say that a body is at rest,it means that it is not in motion,merely means that it is being described with respect to a frame of reference that moving together with the body. Is motion […]
