What is detector efficiency dependent on? For a given detector, efficiency values depend on the type and energy of the incident radiation. For incident charged particles such as alpha particles or beta particles, many detectors have a total efficiency that is close to 100 percent. On what factors does the efficiency of a detector depend? […]
How do you find the radius of a resistance?
How do you find the radius of a resistance? How does resistance (R) of a wire depend on its radius r? R∝LA. R=ρLA. A=πr2. R=ρLπr2. R∝1r2. What are the three determinants of resistance? There are three primary factors that determine the resistance to blood flow within a single vessel: vessel diameter (or radius), vessel length, […]
Why is 1 cubic cm equal to 1 mL?
What happens if you plug a fridge in straight away?
What happens if you plug a fridge in straight away? When a refrigerator is placed in a non-standard position (for example on its side), compressor oil can run out of the compressor and up refrigerant lines. So if you don’t stand it upright and wait, the compressor will pump without sufficient oil — not good. […]
Why does stopping potential depends on frequency?
Why does stopping potential depends on frequency? The stopping potential is more negative for higher frequencies of incident radiations. This means that greater the frequency of incident radiations, greater is the maximum kinetic energy of the photo electrons. That is why a greater retarding potential is required to stop them completely. Is stopping potential negative […]
What is the image distance in normal human eye?
What is the principle of ohmic heating?
What is the principle of ohmic heating? Ohmic heating (joule heating, resistance heating, or electroconductive heating) generates heat by passage of electrical current through food which resists the flow of electricity. Which type of heating is used for food processing? Steam and hot air are the main and conventional heating sources for many food processes. […]
Can you increase temperature without heat?
Can you increase temperature without heat? Yes, it is possible to increase the temperature of a gas without adding heat to it, during adiabatic compression the temperature of a gas increases while no heat is given to it. Hence, internal energy of the gas increases due to which its temperature increases. When the ice melts […]
What gives you energy fast?
What gives you energy fast? Exercise is a natural energy booster, because whenever you do it, oxygen-rich blood surges through your body to your heart, muscles, and brain. Regularly squeezing a workout into your day — even if you can spare only 10 minutes at a time — will help keep your energy levels at […]
What grade is the solar system taught?
What grade is the solar system taught? This lesson for late elementary students (grades 3 – 5) teaches about Earth and Space science using an inquiry approach. It covers objects in the sky and changes in the earth and sky, as students learn the size of each planet, the vastness of space, and some special […]
