Is it better to have high accuracy or high precision? If the final result is a 0.2500″ hole, than you have achieved high accuracy. Precision often refers to how repeatable something is. Ideally, you want high accuracy and precision. Let’s say that you aim to drill (5) 1/4″ holes. Which indicates high precision and low […]
What is dispersion of white light state its causes?
What is dispersion of white light state its causes? The dispersion of white light occurs because different colours of light bend through different angles with respect to the incident ray, as they pass through a prism. The red light bends the least while the violet the most as shown below. The first prism splits the […]
How do you calculate impedance load?
How do you calculate impedance load? Calculating Total Impedance. Add resistances in the same circuit. Total impedance is simple if the circuit has several resistors, but no inductors or capacitors. First, measure the resistance across each resistor (or any component with resistance), or refer to the circuit diagram for the labeled resistance in ohms (Ω). […]
When can a magnetic field occur?
When can a magnetic field occur? Magnetic fields occur whenever charge is in motion. As more charge is put in more motion, the strength of a magnetic field increases. Magnetism and magnetic fields are one aspect of the electromagnetic force, one of the four fundamental forces of nature. What is a normal magnetic field? The […]
Where we can see obtuse angle?
Where we can see obtuse angle? An obtuse angle is a type of angle that is always larger than 90° but less than 180°. In other words, it lies between 90° and 180°. In the given figure, ∠XYZ shows an obtuse angle. What are the real life examples of supplementary angles? Supplementary angles are made […]
Which type of metal transfer is suitable for out of position welding?
Which type of metal transfer is suitable for out of position welding? The GMAW process has two options for filler metals: solid wire and metal-cored wire. These filler metals aren’t classified based on their position capabilities. Out-of-position welding with this process must use short-circuit transfer or pulsed GMAW to achieve a lower heat input and […]
Where is evaporative cooling the most effective?
Where is evaporative cooling the most effective? Evaporative cooling is most effective in climates where average relative humidity is less than 30%. As humidity increases, and the cooling capability declines, the temperature difference between the outside and inside of the chamber decreases. How does evapotranspiration cool the air? Evapotranspiration includes the evaporation of water from […]
What are the 4 basic components of all cells?
What are the 4 basic components of all cells? All cells share four common components: (1) a plasma membrane, an outer covering that separates the cell’s interior from its surrounding environment; (2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; (3) DNA, the genetic material of the […]
Who buys preferred stock?
Who buys preferred stock? For individual retail investors, the answer might be “for no very good reason.” It’s not generally known, but most preferred shares are purchased by institutional investors at the time the company first goes public because they have an incentive to buy preferred shares that individual retail investors do not: the so- […]
What year will the world population reach 9 billion?
What year will the world population reach 9 billion? An analysis from the Wittgenstein Center IISA predicts global population to peak in 2070 at 9.4 billion and then decline to 9.0 billion in 2100. Is human population decreasing? Up until the beginning of the industrial revolution, global population grew very slowly. After about 1800 the […]
