Why is apparent weight less than true weight? A floating or immersed object is not accelerating upwards or downwards, so there can be no net force. In fact, buoyancy provides a supporting force exactly as the ground does. Objects also experience some buoyancy in air, so even in air the normal force (apparent weight) is […]

What is the difference between zoning laws and building codes?
What is the difference between zoning laws and building codes? ZONING THE IMPORTANT DISTINCTION BETWEEN ZONING CODES AND BUILDING CODES is that, while zoning codes and zoning permits are concerned with land use, building codes and building permits deal exclusively with the structure itself. What do the different zoning codes mean? NSW (New South Wales) […]
What causes the Zeeman effect?
What causes the Zeeman effect? The reason for the Zeeman effect is that in a magnetic field, the angular momentum quantum state can undergo a displacement from degeneracy. The effect is due to the distortion of the electron orbitals because of the magnetic field. The (normal) Zeeman effect can be understood classically, as Lorentz predicted. […]

Is it OK to sleep with purple lights on?
Is it OK to sleep with purple lights on? A research team from Oxford University have shown how different colours of light could affect our ability to sleep. Blue and violet light delayed sleep – the onset of sleep taking between 16 and 19 minutes for blue and between 5 and 10 minutes for violet. […]
How reliable is hair evidence?
How reliable is hair evidence? Although the science of microscopic hair examination can never result in an identification, that is, conclude that a hair came from one individual to the exclusion of all others, the vast amount of both macroscopic and microscopic information available from hair analysis can provide a strong basis for an association […]
What is the major element found in eggs?
What is the major element found in eggs? The egg yolk contains 1 % minerals, with phosphorus as the most abundant mineral component. More than 60 % of the total phosphorus in egg yolks is contained in phospholipids. The major inorganic components of egg white are sulfur, potassium, sodium, and chloride. Is eating rock salt […]
What factors determine whether a collision between two reactant molecules will result in a reaction quizlet?
What factors determine whether a collision between two reactant molecules will result in a reaction quizlet? 14.51. (a) What factors determine whether a collision between two molecules will lead to a chemical reaction? The energy of collision and the orientation of the molecules when they collide determine whether a reaction will occur. What two factors […]
Does magic work on Superman?
Does magic work on Superman? The reason for this is simple – his powers occurred as a result of a natural phenomenon, rather than anything supernatural. This means that magic affects him the way it affects anyone else; he’s just as vulnerable to it as normal humans are. In fact, magic seems to have very […]
