Why is SI easier than the English system? There are several reasons why SI is preferred to the old English system of measurement: SI uses base 10, just like our number system, so it is much easier to learn, remember and convert between units. The prefixes used in SI are from Latin and Greek, and […]

What does the radial velocity method measure?
What does the radial velocity method measure? The radial velocity technique is able to detect planets around low-mass stars, such as M-type (red dwarf) stars. This allows astronomers to determine the inclination of the planet’s orbit, which enables the measurement of the planet’s actual mass. Why is the radial velocity method biased towards high mass […]
What is killing the coral reefs?
What is killing the coral reefs? Despite their importance, warming waters, pollution, ocean acidification, overfishing, and physical destruction are killing coral reefs around the world. Genetics is also becoming a larger area of coral research, giving scientists hope they might one day restore reefs with more heat tolerant coral. How are humans killing coral reefs? […]

Can a body have zero velocity and still acceleration give example?
Can a body have zero velocity and still acceleration give example? Yes, a body with a velocity 0 can still accelerate. The simplest example is a body which is thrown up. At the peak point its velocity becomes 0 but still accelerates due to gravity. How can you have acceleration but no velocity? Since acceleration […]
How much heat and pressure is needed for fusion?
How much heat and pressure is needed for fusion? Fusion requires temperatures of about 100 million Kelvin (approximately six times hotter than the sun’s core). At these temperatures, hydrogen is a plasma, not a gas. Plasma is a high-energy state of matter in which all the electrons are stripped from atoms and move freely about. […]
