Why are house hold appliances connected in parallel? Electrical appliances are connected in a parallel arrangement in a house circuit because: Each appliance gets full voltage as resistance in a parallel arrangement is low. If one appliance fuses, it does not affect the working of other appliances. Why are household appliances connected to the 120 […]
What are the types of boundary layer?
What are the types of boundary layer? There are two different types of boundary layer flow: laminar and turbulent. The laminar boundary is a very smooth flow, while the turbulent boundary layer contains swirls or “eddies.” The laminar flow creates less skin friction drag than the turbulent flow, but is less stable. What are the […]
What exercises improve speed?
What exercises improve speed? Running Workouts to Build Speed Interval Runs. Intervals runs are like HIIT workouts: you work at high intensity for a short period of time, recover, and do it again. Fartleks. Long, Slow Runs. Leg Strength Exercises to Improve Speed. Sled Push. Ladder Drills. High Knees. Dot Drills. How can I increase […]
What if 2 positive charges come together?
What if 2 positive charges come together? In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a repulsive force upon a second positively charged object. This repulsive force will push the two objects […]
What is difference between system and surrounding?
What is difference between system and surrounding? The system consists of those molecules which are reacting. The surroundings are everything else; the rest of the universe. For example, say the above reaction is happening in gas phase; then the walls of the container are part of the surroundings. What are the examples of open and […]
Is geothermal or solar better?
Is geothermal or solar better? However, for most residential and commercial property owners, geothermal energy can only be used as a heating and cooling solution, while solar energy can generate electricity with photovoltaic (PV) technology. For anyone looking to save money on electricity bills, installing solar energy is the way to go. Which type of […]
What is the difference between the Gulf Stream and the North Atlantic drift?
What is the difference between the Gulf Stream and the North Atlantic drift? Properties. The Gulf Stream proper is a western-intensified current, driven largely by wind stress. The North Atlantic Drift, in contrast, is largely driven by thermohaline circulation. How does North Atlantic drift affect climate? The relatively warm waters of the North Atlantic Drift […]
What is the volume of 10 mL of water in a graduated cylinder?
What is the volume of 10 mL of water in a graduated cylinder? In the 10-mL graduated cylinder, first subtract 8 mL – 6 mL = 2 mL. Next, count that there are ten intervals between the labeled graduations. Therefore, the scale increment is 2 mL/10 graduations = 0.2 mL/graduation. What does each line represent […]
Why sodium lamp is used in polarimeter?
Why sodium lamp is used in polarimeter? A polarimeter is defined as a scientific instrument that is used for measuring the angle of rotation caused by the passing of polarized light through an optically active substance. For this sodium light is used because it produces monochromatic light and the energy output is high. Which light […]

San Rafael Mountains, Southern California. Santa Ynez Mountains, Southern California. Tehachapi Mountains, Southern California. Topatopa Mountains, Southern California. What is the oldest mountain in the United States? Black Hills How […]
