How far can a human see? The Earth curves about 8 inches per mile. As a result, on a flat surface with your eyes 5 feet or so off the ground, the farthest edge that you can see is about 3 miles away. Which animal has better vision than humans? Eagles. All birds of prey […]

What is the formula of finding volume? Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height. How many cubes fit in a rectangular prism? You find the dimensions of the total prism and then divide it by how […]

Is yellow lightning real? Lightning also can take on a range of colors, depending on conditions in the clouds and in the air. Yellow or orange lightning occurs when there is a large concentration of dust in the air. White lightning is a sign of low humidity or a little amount of moisture in the […]

What is rarefaction and compression? Compression and Rarefaction. • Compression- a region in a longitudinal (sound) wave where the particles are closest together. • Rarefaction- a region in a longitudinal (sound) wave where the particles are furthest apart. What is compression of a wave? A compression is a region in a longitudinal wave where the […]

Why does my flask not stay hot? Could be the hot boiling water. A seal that is heat sensitive (ok for hot water but not boiling hot water) could be damaged with the excessive heat. I have used an old steel Thermos for 20 years and it still keeps my coffee hot all day. The […]

What keeps the moon in position? This constant tug on the Moon as it moves around the Earth is called a “centripetal” force. This force is balanced by the “centrifugal” force, that pulls on the Earth and keeps the moon in motion. Because the centrifugal force exactly balances the centripetal force. What are some words […]

How are both curiosity and skepticism useful in science? Curiosity is the stem from which experiments are born. Curiosity can lead to new innovations. Skepticism can help verify the […]

Why do metal atoms lose electrons? Metal atoms lose electrons to nonmetal atoms because metals typically have relatively low ionization energies. Metals at the bottom of a group lose electrons more easily than those at the top. How do metal atoms become stable? The reactions of elements are related to the number of electrons in […]
