Does photoelectric current depend on frequency? Photoelectric effect can be explained as: it takes a specific energy to launch an electron from a metal surface. This energy is the work function which relies upon the metal. Electrons can pick up energy by collaborating with photons. Current is not dependent on the frequency of photons. What […]
Does spring constant depend on gravity?
Does spring constant depend on gravity? Gravity has nothing to do with the spring constant. It can only effect the net force on the spring depending on the orientation of the spring. If the spring is oriented horizontally, gravity has no effect. Does spring constant change with compression? The proportional constant k is called the […]
What are some industries in which aggregate planning would be particularly important why give at least?
What are some industries in which aggregate planning would be particularly important why give at least? Aggregate planning is useful in many types of manufacturing and services. Manufacturers include furniture, all durable goods, consumer electronics, textiles, motor vehicles, and aircraft, Service industries might be restaurants and other hospitality providers like hotels and motels. Which are […]

Can electrons exist alone?
Can electrons exist alone? Electrons have mass, charge, angular momentum, an intrinsic magnetic moment and helicity, but they have no known substructure. No two electrons can occupy the same space at the same time. They are part of every atom but they can exist separately on their own as well. What happens to the atoms […]
Why is poverty a threat?
Why is poverty a threat? The indignity and sufferings of people living in poverty is a humanitarian tragedy. It is a challenge putting pressure on all societies. Poverty is the root cause of many problems, posing a severe and distinct threat to food security, climate change resilience, insecurity, democracy, human rights amongst others. What poverty […]
Does all water run through water heater?
Does all water run through water heater? The cold water service line slopes away from the water heater after splitting from the main line. Instead of sending water through the heater, cold water service lines run directly to every water appliance in the home. To get to every appliance, these pipes need to run throughout […]
Can you differentiate tangential velocity and tangential acceleration?
Can you differentiate tangential velocity and tangential acceleration? If the tangential velocity is not changing directions, then the object is not moving in a circle. Tangential acceleration results from the change in magnitude of the tangential velocity of an object. An object can move in a circle and not have any tangential acceleration. How do […]
What is effect of intensity of light?
What is effect of intensity of light? Intensity cannot change the cut off frequency or stopping potential. High intensity means more number of photons, so chances of hitting to electron by them increase and hence more photo electron are emitted i.e., photo current increases. Why intensity decreases as distance from the light source increases this […]
Does it matter where you put the dots on a Lewis structure?
Does it matter where you put the dots on a Lewis structure? In almost all cases, chemical bonds are formed by interactions of valence electrons in atoms. To facilitate our understanding of how valence electrons interact, a simple way of representing those valence electrons would be useful. Again, it does not matter on which sides […]
