Can too much ultraviolet light can cause cancer? Too much UV radiation from the sun or sunbeds can damage the genetic material (the DNA) in your skin cells. If enough DNA damage builds up over time, it can cause cells to start growing out of control, which can lead to skin cancer. Anyone can develop […]
How do you prove drift velocity?
How do you prove drift velocity? When electrons with density n and charge Q causes a current ‘I’ to flow through a conductor of cross-sectional area A, Drift velocity v can be calculated through the formula I = nAvQ. What is the relation between current and drift velocity? Current is the flow of free charges, […]
How can I enjoy physics?
How can I enjoy physics? Instead of memorizing formulas, it is better to understand the derivations. Mugging up a number of formulas will only make you more apprehensive of the subject. Rather, if you try and understand where they come from, you will start enjoying physics and its applications! Can you self teach physics? Physics […]

Is Anammox an nitrification?
Is Anammox an nitrification? Compared to conventional nitrification/denitrification in activated sludge systems, Anammox eliminates the necessity of an organic carbon source for nitrification, reduces energy demand for aeration and has a smaller production of excess sludge and lower CO2 emissions (BERTINO 2010). Why does Anammox occur? The anammox process occurs under anaerobic conditions by bacterial […]
What are 5 factors that affect reaction rate?
What are 5 factors that affect reaction rate? Five factors typically affecting the rates of chemical reactions will be explored in this section: the chemical nature of the reacting substances, the state of subdivision (one large lump versus many small particles) of the reactants, the temperature of the reactants, the concentration of the reactants, and […]
Is 42 psi too much for tires?
What do scientists mean when they describe light as having a wave-particle duality quizlet?
What do scientists mean when they describe light as having a wave-particle duality quizlet? – Light is made up of electric and magnetic energy. – Light can travel through a vacuum. What do scientists mean when they describe light as having a wave-particle duality? That light is both a wave and a particle simultaneously. (Light […]
Why is volumetric efficiency less than 100?
Why is volumetric efficiency less than 100? If the cylinder is filled with fuel/air at atmospheric pressure, then the engine is said to have 100% volumetric efficiency. However, if the cylinder is pulling in a vacuum, then the engine has less than 100% volumetric efficiency. Normally aspirated engines typically run anywhere between 80% and 100% […]
