What is break even analysis and its assumptions? 1. Break-even analysis is based on the assumption that all costs and expenses can be clearly separated into fixed and variable components. It assumes that fixed costs remain constant at all levels of activity. It should be noted that fixed costs tend to vary beyond a certain […]
Does an object on the ground have potential energy?
Does an object on the ground have potential energy? Potential energy is energy that is stored in a person or object. The object has the potential to fall due to gravity. Gravitational potential energy depends on an object’s weight and its height above the ground (GPE = weight x height). Elastic potential energy is due […]

How often does aurora australis occur?
How often does aurora australis occur? Most southern lightshows occur during the Southern Hemisphere’s fall and winter months, which stretch from March through September. Here are four aurora australis hotspots for those looking for a southern celestial spectacle. What are the two most common and two most rare colors seen in auroras? The colors most […]
What happens when you mix sodium and chlorine?
What happens when you mix sodium and chlorine? If sodium metal and chlorine gas mix under the right conditions, they will form salt. The sodium loses an electron, and the chlorine gains that electron. This reaction is highly favorable because of the electrostatic attraction between the particles. In the process, a great amount of light […]
Do waves transfer mass?
Do waves transfer mass? Waves transfer energy but not mass. What waves transfer matter as they travel? Mechanical waves Can sound waves travel where there is no matter? Sound cannot travel through a vacuum. A vacuum is an area without any air, like space. So sound cannot travel through space because there is no matter […]
Is inhaling helium bad?
Is inhaling helium bad? The more pure helium you inhale, the longer your body is without crucial oxygen. Breathing in pure helium can cause death by asphyxiation in just minutes. Inhaling helium from a pressurized tank can also cause a gas or air embolism, which is a bubble that becomes trapped in a blood vessel, […]
Can coefficient of drag be greater than 1?
Can coefficient of drag be greater than 1? Two objects having the same reference area moving at the same speed through a fluid will experience a drag force proportional to their respective drag coefficients. Coefficients for unstreamlined objects can be 1 or more, for streamlined objects much less. Does drag coefficient change with size? The […]
Can you hear a radio wave?
Can you hear a radio wave? Yes, humans, under special circumstances, can hear radio-frequency pulses in the range of 2.4MHz to 10GHz (corresponding to radio frequencies and microwave) as buzzes, clocks, hiss or knocking at apparent auditory frequencies of 5kHz and higher (very high-pitched). … Can teeth pick up radio signals? The electrical conductivity of […]
