The main variables in a science experiment are the independent ... Dependent Variable is the mass of the object. Control Variables are the material of the object, room temperature, and temperature ...

Mars’ strangely small mass still puzzles planetary scientists. Definitive answers as to why are still hard to come by.

According to the theory of general relativity, a galaxy must have a certain amount of mass to be held together by gravity. However, scientists don’t see enough visible mass in many galaxies in ...

F or the first time, scientists have observed a collection of particles, also known as a quasiparticle, that's massless when moving one direction but has mass in the other direction. The ...

of~an~element} = \frac{mass~of~an~element~in~the~compound}{relative~formula~mass~M_r} \times 100\) There are six atoms of hydrogen in the compound, so the mass of hydrogen is 6 × 1 = 6.

A collection of particles known as a quasiparticle has been detected behaving as if it has mass when it moves in one direction, but becomes massless when moving at right angle. Improbable as this ...

Mass extinctions have the potential to guide modern conservation efforts, say scientists. A study confirms the idea that upheavals of the geological past caused a drastic loss of biodiversity ...
