Which of the following is not a line standard? Explanation: Length bar is an end standard. Yard, meter and precision scale are line […]
What is solar wind caused by?
What is solar wind caused by? The solar wind is created by the outward expansion of plasma (a collection of charged particles) from the Sun’s corona (outermost atmosphere). This plasma is continually heated to the point that the Sun’s gravity can’t hold it down. It then travels along the Sun’s magnetic field lines that extend […]
What is the octet rule of covalent bonding?
What is the octet rule of covalent bonding? The Octet Rule requires all atoms in a molecule to have 8 valence electrons–either by sharing, losing or gaining electrons–to become stable. For Covalent bonds, atoms tend to share their electrons with each other to satisfy the Octet Rule. Which type of bond is formed when two […]

What do you call the highest of a wave?
What do you call the highest of a wave? The highest surface part of a wave is called the crest, and the lowest part is the trough. The vertical distance between the crest and the trough is the wave height. The horizontal distance between two adjacent crests or troughs is known as the wavelength. What […]
Why is exit wound bigger than entry?
Why is exit wound bigger than entry? Exit wounds – as we have already mentioned – are usually larger than the entrance wound and this is because as the round moves through the body of the victim it slows down and explodes within the tissue and surrounding muscle. How can firearms and bullets be used […]
What is wrong with the steady state theory?
What is wrong with the steady state theory? In the Steady State the Universe was always the same so it never produced a blackbody. Hence the existence of a blackbody background ruled out the Steady State. In addition, the temperature of the cosmic background can be measured in some very distant clouds that produce absorption […]
Is elevation based on sea level?
Is elevation based on sea level? Sea level is the base level for measuring elevation and depth on Earth. Because the ocean is one continuous body of water, its surface tends to seek the same level throughout the world. Just like the ocean, the elevation of land may rise and fall over time. How do […]
