Does Higgs boson prove dark matter? ATLAS concluded at a 95% confidence level that no more than 13% of Higgs bosons produced in the LHC could transform into invisible particles. These findings place the strongest limits so far on Higgs transformations to such invisible particles. What is God particle in simple words? In 2012, scientists […]
How is the 21 cm line of hydrogen formed?
How is the 21 cm line of hydrogen formed? The hydrogen line, 21-centimeter line, or H I line is the electromagnetic radiation spectral line that is created by a change in the energy state of neutral hydrogen atoms. This line is also the theoretical basis of hydrogen maser. What is the 21-cm line used for? […]
Where do light rays converge?
Where do light rays converge? A convex lens is also called a converging lens because it makes parallel light rays passing through it bend inward and meet (converge) at a spot just beyond the lens known as the focal point. Photo: A convex lens makes parallel light rays converge (come together) at the focal point […]
What happens if you add more product to a reaction?
What happens if you add more product to a reaction? According to Le Chatelier’s principle, adding additional reactant to a system will shift the equilibrium to the right, towards the side of the products. If we add additional product to a system, the equilibrium will shift to the left, in order to produce more reactants. […]
Does white light absorb all colors?
Does white light absorb all colors? A white object reflects all colors of white light equally. If an object absorbs all colors but one, we see the color it does not absorb. The yellow strip in the following figure absorbs red, orange, green, blue, indigo and violet light. When a color is removed from white […]
What is the chance that a child will inherit the disorder if one parent is heterozygous for this gene and one parent has cystic fibrosis?
What is the chance that a child will inherit the disorder if one parent is heterozygous for this gene and one parent has cystic fibrosis? For example in cystic fibrosis if both parents are heterozygous, each child has a 25% chance of being born with cystic fibrosis. Some genetic diseases are caused by a dominant […]
Which two player positions are the only ones that can shoot?
Which two player positions are the only ones that can shoot? Goal Attack (GA) and Goal Shooter (GS) are the only players allowed to shoot and score goals. Shots must be taken within the shooting circle, sometimes referred to as the D or semi-circle. Can you bounce the ball off the post in netball? A […]
How is work related to internal energy?
How is work related to internal energy? The relationship between the internal energy of a system and its heat and work exchange with the surroundings is: E = q + w (The form of work will be restricted to gaseous, PV-type for this discussion.) Interestingly, both q and w are not state functions. What is […]
How does humidity relate to weather?
How does humidity relate to weather? The higher the humidity, the wetter it feels outside. On the weather reports, humidity is usually explained as relative humidity. Relative humidity is the amount of water vapor actually in the air, expressed as a percentage of the maximum amount of water vapor the air can hold at the […]
What affects boiling point of water?
What affects boiling point of water? Atmospheric pressure influences the boiling point of water. When atmospheric pressure increases, the boiling point becomes higher, and when atmospheric pressure decreases (as it does when elevation increases), the boiling point becomes lower. Pressure on the surface of water tends to keep the water molecules contained. Can a tea […]
