Why does GM counter need quenching? Quenching. When a GEIGER-MULLER tube operates in Geiger region, the secondary electrons increase the current pulse by further ionization of gas molecules. Therefore, it is desirable to prohibit the production of spurious pulse following the main required plus due to a single particle entry. Can GM counter detect neutrons? […]
What is the nature of a real image?
Why are leaves pink?
Why are leaves pink? If the plants break down the chlorophyll and move it out of their leaves before the leaves fall, plants save energy. The plants can reabsorb the molecules that make up chlorophyll. Anthocyanins are other plant pigments that are only made in the fall. These pigments cause red, pink, or purple colors. […]
How big should a mirror be above a fireplace?
What happens when intensity is doubled?
What happens when intensity is doubled? Any change in the energy of the photons will not change the intensity. So if intensity is doubled, the no. of photons incident on the surface will be doubled and as a result more photoelectrons will be ejected. What is the value of maximum usable frequency when the incident […]
What is the purpose of Critical Mass?
What is the purpose of Critical Mass? A company’s critical mass is important because it marks the difference between thriving and surviving in a market environment. When these conditions have been met, the company has reached critical mass. What is the definition of critical mass? : a size, number, or amount large enough to produce […]
Which state of matter has the most kinetic energy?
Which state of matter has the most kinetic energy? gaseous Do liquids have kinetic energy? Liquids have more kinetic energy than solids. If you add heat energy to a liquid, the particles will move faster around each other as their kinetic energy increases. Some of these particles will have enough kinetic energy to break their […]
What type of energy does a roller coaster have at the top of a hill?
What type of energy does a roller coaster have at the top of a hill? kinetic energy Does a roller coaster have mechanical energy? They make each hill that follows smaller to compensate for this decrease in mechanical energy. Eventually the roller coaster changes most of its mechanical energy and is able to come to […]
Why is hydrogen so special?
Why is hydrogen so special? Hydrogen is a colorless gas that is so much lighter than air that it can actually escape the gravitational pull of the earth and shoot off into space. Hydrogen is also the first element on the periodic table and has only on proton and one electron. Hydrogen does not have […]
How does distance from the ocean affect climate?
How does distance from the ocean affect climate? Distance from the sea – Oceans heat up and cool down much more slowly than land. This means that coastal locations tend to be cooler in summer and warmer in winter than places inland at the same latitude and altitude. Why are coastal areas more stable climates? […]
