What are the advantages of incandescent light bulbs? Advantages of Incandescent Bulb ➨It is less expensive due to lower initial cost. ➨It is easier to dim with rheostats. ➨It produces warmer color compare to fluorescent and thungsten-halogen lamps. ➨It generates relatively high light output. What are advantages and disadvantages of a standard incandescent light bulb? […]
What is the kinetic energy of a molecule?
What is the kinetic energy of a molecule? Kinetic Energy and Molecular Speed Gas particles are in constant motion, and any object in motion has kinetic energy (Ek). Kinetic energy, for an individual atom, can be calculated by the following equation where m is the mass, and u is the speed. How does temperature relate […]
What are the causes of strain?
What are the 5 main electron group geometries?
What are the 5 main electron group geometries? Electron group geometries refer to the five geometries: linear, trigonal planar, tetrahedral, trigonal bipyramidal, or octahedral. If one or more of the bonding pairs of electrons is replaced with a lone pair, the electron geometry does not change but the the shape of the molecule is altered. […]
What type of risk factor is age?
What type of risk factor is age? Abstract. The risk of developing cardiovascular disease (CVD) is generally dependent on the presence or absence of traditional risk factors. Age is a well-known traditional risk factor, generally considered nonmodifiable. What are the two type of risk factors? Types of Risk Broadly speaking, there are two main categories […]
What does CSF feel like?
What does CSF feel like? Symptoms of a cerebrospinal fluid (CSF) leak can include: Headache, which feels worse when sitting up or standing and better when laying down; may come on gradually or suddenly. Vision changes (blurred vision, double vision, visual field changes) Hearing changes/ringing in ears. Where can CSF be found? The CSF occupies […]
What is the correct order that sperm would have to travel to fertilize an egg?
What is the correct order that sperm would have to travel to fertilize an egg? Before fertilization can take place, the sperm must be deposited in the vaginal vault, pass through the tiny opening of the cervix, swim through the uterus, and reach the fallopian tubes. Which of the followings shows the correct pathway of […]
Which best describes the shape of a convection current?
Which best describes the shape of a convection current? The shape of a convection current would be circular. Convection currents are caused by the very hot material at the deepest part of the mantle rising, then cooling, sinking again and then heating, rising and repeating the cycle over and over. How are convection currents used […]
Does a resistor stop the flow of electricity?
Does a resistor stop the flow of electricity? Resistors control how much electric charge flows through a circuit each second – the size of the current in the circuit. They do this by controlling how difficult it is for electric charges to flow in the circuit – that is, the resistance in the circuit. Do […]
What are the 4 types of mining?
What are the 4 types of mining? There are four main methods of mining: underground, surface, placer and in-situ. The type of mining method used depends on the kind of resource that is being targeted for extraction, the deposit’s location below or on the Earth’s surface and the capacity of each method to profitably extract […]
