Where is pair production used? Pair production also can occur in the field of an atomic electron, to which considerable recoil energy is thereby imparted. The threshold for such a process is four times the rest energy of an electron, or 4mc2. The total pair-production cross section is the sum of the two components, nuclear […]
What are 3 examples of the evidence of energy?
What are 3 examples of the evidence of energy? Heat, sound, light and motion are evidence of energy in a system. Students will be able to reflect on what they have learned and review key vocabulary. They will consider ways they use energy each day and identify systems or behaviors they could change in order […]
What is the difference between a KCAL and a calorie?
What is the difference between a KCAL and a calorie? A kilocalorie is another word for what’s commonly called a calorie, so 1,000 calories will be written as 1,000kcals. The label will usually tell you how many calories are contained in 100 grams or 100 millilitres of the food or drink, so you can compare […]
What are the values of gas constant R?
What are the values of gas constant R? Gas constant Values of R Units 8.31446261815324 kg⋅m2⋅s−2⋅K−1⋅mol−1 Other Common Units 0.730240507295273 atm⋅ft3⋅lb⋅mol−1⋅°R−1 10.731557089016 psi⋅ft3⋅lb⋅mol−1⋅°R−1 What is the physical significance of gas constant R? Physically, the gas constant is theconstant of proportionality that happens to relate the energy scale in physics to the temperature scale, when a […]
How do I make use of electrical charges in daily life?
How do I make use of electrical charges in daily life? Static electricity has several uses, also called applications, in the real world. One main use is in printers and photocopiers where static electric charges attract the ink, or toner, to the paper. Other uses include paint sprayers, air filters, and dust removal. Why are […]
What happens when force is applied on a moving body?
What happens when force is applied on a moving body? The action from a force can cause an object to move or speed up (accelerate), to slow down (decelerate), to stop, or to change direction. Since any change in velocity is considered acceleration, it can be said that a force on an object results in […]
What kills voltage or current?
What kills voltage or current? Current will kill you but some amount of voltage is required to flow that current in the body breaking the human body resistance. In other words, an enough power is required to pass in the human body for proper electric shock. What happens to power when voltage is doubled? As […]
Which is the property of alkynes?
Which is the property of alkynes? Alkynes are nonpolar, unsaturated hydrocarbons with physical properties similar to alkanes and alkenes. Alkynes dissolve in organic solvents, have slight solubility in polar solvents, and are insoluble in water. Compared to alkanes and alkenes, alkynes have slightly higher boiling points. Which is a property of both alkenes and alkynes? […]

Is nature stronger than nurture?
Is nature stronger than nurture? (PhysOrg.com) — Nurture could have an even greater effect than originally thought, according to a University of Manchester study that is set to shake up the ‘nature versus nurture’ debate. What is difference between nature and nurture? Nature is what we think of as pre-wiring and is influenced by genetic […]
