Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915), which describes gravity not as a force, but as a consequence of masses moving along geodesic lines in a curved spacetime caused by the uneven distribution of mass. Who actually discovered gravity first?Read More →
Creator Alex Hirsch said in a post on Tumblr that he made the decision to end the series after only two seasons — not because it wasn’t doing well, but because that’s exactly how long he’d intended it to run for. No more, no less. … “Gravity Falls was neverRead More →
The specific gravity stands for a dimensionless unit that defines the ratio of density of a substance to the density of water. … The specific weight corresponds to the weight per unit of the volume and can be calculated from the specific gravity. What is the unit and dimension ofRead More →
Specific gravity is dependent on the temperature, and most of the values found in the literature refer to STP conditions. Although the two terms often are used interchangeably, there is a technical difference between specific gravity and density. Density is defined as the mass per unit volume of a substance.Read More →
Specific gravity is the ratio of a material’s density with that of water at 4 °C (where it is most dense and is taken to have the value 999.974 kg m–3). It is therefore a relative quantity with no units. What does the specific gravity actually measure? It measures theRead More →
The quarks move so fast inside each neutron–close to the speed of light–that according to relativity theory, space and time look different to each of the quarks, which renders some scattering results ambiguous. Why is the gluon massless? The Higgs has a weak charge and therefore interacts with the WRead More →
Gravity is affected by two variables. … Distance is inversely proportional (as one goes up, the other goes down) to the strength o gravity. In other words, the greater the distance between two objects, the lower the strength of gravity is between them. Does gravitational field strength increase with distance?Read More →
Specific gravity has many other applications: gemologists use it to distinguish similar gems; chemists, to check on the progress of reactions and the concentration of solutions; and auto mechanics, to test battery fluid and antifreeze. Why do scientists use specific gravity? Specific gravity can be used to determine if anRead More →
Isaac Newton changed the way we understand the Universe. Revered in his own lifetime, he discovered the laws of gravity and motion and invented calculus. Who discovered gravity before Isaac Newton? JAIPUR: A Rajasthan minister known for his controversial remarks has now claimed that Indian mathematician and astronomer Brahmagupta-II (598-670)Read More →
How does gravity affect density? The gravity of the body will work to increase its density. If we think of gravity as a force then to achieve equilibrium something needs to counteract the force of gravity, usually electromagnetic repulsion caused by neighboring electron shells. Does gravity affect mass? Mass– theRead More →
