What is the minimum size power conductors that are permitted to be run in parallel? Parallel conductor installations are covered in NEC 310.10(H) and are permitted for each phase, polarity, neutral, or grounded conductor in sizes 1/0 AWG and larger. Joining conductors in parallel is like having two or more smaller conductors connected at each […]
How Machines make our life easier?
How Machines make our life easier? But how do these machines help? Simple machines make our lives easier by changing the amount of force or the direction of the force being applied (added). There are four simple machines that we use most often in our lives. An inclined plane is a slanted surface that helps […]
How much heat can a resistor take?
What are the six different types of chemical reactions?
What are the six different types of chemical reactions? Six common types of chemical reactions are: synthesis, decomposition, single-displacement, double-displacement, combustion and acid-base reactions. Scientists classify them based on what happens when going from reactants to products. Can a synthesis reaction have 3 reactants? 1 Answer. The production of group 1 and group 2 hydrogen […]
How can you tell the difference between aluminum and magnesium?
How can you tell the difference between aluminum and magnesium? Most recent answer Magnesium versus aluminum is highly reactive and less stable than aluminum. Magnesium, when compared to aluminum, is softer and more expensive, and has the tendency to bend easily. Magnesium, when compared to aluminum, is lightweight and valuable, whereas forged aluminum is stronger. […]
What is balanced force give an example?
What is balanced force give an example? When two forces are the same strength but act in opposite direction, they are called balanced forces. Again, tug-of-war is a perfect example. If the people on each side of the rope are pulling with the same strength, but in the opposite direction, the forces are balanced. The […]
What do u mean by uniform circular motion?
What do u mean by uniform circular motion? Uniform circular motion can be described as the motion of an object in a circle at a constant speed. As an object moves in a circle, it is constantly changing its direction. At all instances, the object is moving tangent to the circle. Nonetheless, it is accelerating […]
Is ultrasound tech school hard?
Is ultrasound tech school hard? Difficult but Worth the Effort It takes two years to complete, but the degree from a CAAHEP accredited program qualifies the sonography student to take the ARDMS exams. It is necessary to take required courses like physiology, anatomy, physics, sonography instrumentation and medical terminology. Which is the best ultrasound machine? […]
What weather do cold fronts bring?
What weather do cold fronts bring? A cold front forms when a cold air mass pushes into a warmer air mass. Cold fronts can produce dramatic changes in the weather. As the cold front passes, winds become gusty. There is a sudden drop in temperature, and also heavy rain, sometimes with hail, thunder, and lightning. […]
What frequency is gamma rays?
What frequency is gamma rays? Gamma rays have frequencies greater than about 10^19 cycles per second, or hertz (Hz), and wavelengths of less than 100 picometers (pm), or 4 x 10^9 inches. (A picometer is one-trillionth of a meter.) Is there a shorter wavelength than gamma rays? Electromagnetic energy travels as waves that vary in […]
