What can we learn from radial velocity? The radial velocity technique is able to detect planets around low-mass stars, such as M-type (red dwarf) stars. This is due to the fact that low mass stars are more affected by the gravitational tug of planets and because such stars generally rotate more slowly (leading to more […]
How can joints be classified?
How can joints be classified? A joint is defined as a connection between two bones in the skeletal system. Joints can be classified by the type of the tissue present (fibrous, cartilaginous or synovial), or by the degree of movement permitted (synarthrosis, amphiarthrosis or diarthrosis).

Which conditions are necessary for hydrogen fusion?
Which conditions are necessary for hydrogen 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. What is […]
How many bonds can sulfur make with elements?
How many bonds can sulfur make with elements? two bonds Is Sulfur more electronegative than calcium? Sulfur is more electronegative than calcium. Is oxygen more electronegative than sulfur? Electronegativity. Sulfur is less electronegative than oxygen (2.4 and 3.5, respectively) and as a consequence bonds to sulfur are less polar than the corresponding bonds to oxygen. […]
