What is the explanation for the features of repeaters?
Signal strength diminishes over distance. A repeater boosts signal strength and passes it on.
What is the deicbel loss of a signal that starts at point A with a strength of 2000 watts and ends at point B with a strength of 400 watts?
What is the decibel loss of a signal that starts at point A with a strength of 2000 watts and ends at point B with a strength of 400 watts?That is impossiple. If you have a light bulb of 100 watts. This power stays fixed in the lamp and does not decrease with distance!If you mean a sound source, only the sound pressure in pascals or the sound pressure level in dB is decreasing with distance from the source. Or the sound intensity in watts per square meter or the sound intensity level in watts is decreasing with distance.Scroll down to related links and look at "Sound intensity I and the inverse square law 1/r2"This question is talking about the fundamentals between data and signals in data communication. It has nothing to do with a light bulb and is not impossible. Here is how it is done. The decibel is a relative measure of signal loss or gain and is expressed as dB = 10 × log10 (P2 / P1) in which P2 and P1 are the ending and beginning power levels of the signal expressed in watts.So in this case where a signal starts with a strength of 2000 watts and ends with a strength of 400 watts the calculation would be:dB = 10 × log10 (400 /2000)dB = 10 × log10 (.2)dB = 10 × (-.69)dB = -6.9dB
How are plastics catergorised?
They are classified according to their strength, rigidity, plasticity, and boiling/melting temperatures. They are classified according to their strength, rigidity, plasticity, and boiling/melting temperatures.
What is difference between limit of proportionality and tensile strength?
The proportional limit is the stress value at which the stress is no longer linear with strain. After that, the material will begin to yield and become non-linear, or plastic, and then it will fail at a higher value called the tensile strength. For most metals, the proportional limit is well below the tensile strength; for example annealed stainless steel has a proportional limit near 30 ksi and tensile strength of 80 ksi; aluminum has a proportional limit of 35 ksi and tensile strength of 42 ksi.
What SWAT analysys of online banking?
SWOT stands for: Strength Weaknesses Opportunities Threats So you would list the Strength's, Weaknesses, Opportunities, and Threats to an online bank.
Method and calculation of impact strength?

How is geometry used in nature buildings and roads?
Look into the strength of a snail's shell for geometry in nature, the strength of arches for geometry in buildings and the use of angles, arcs and radiuses in designing roads.
What is shearing mechanism?
shearing mech. process is done by a machine known as shearing machine in which a sheet of alluminium or some other metal is cutted down in between the blade of the machine, and this process is known as shearing process.
What has the author F A De Lory written?
F. A. De Lory has written: 'An investigation of discrepancies in undrained shearing strength test results in clay' -- subject(s): Clay, Shear strength of soils, Testing
How are compression tension and shearing similar?
Compression, tension, and shearing are all types of mechanical stresses that occur in materials. Compression involves forces that act to compress or shorten the material, while tension involves forces that act to stretch or elongate the material. Shearing involves forces that act parallel to a surface, causing sliding or distortion of material layers. All three types of stress can cause deformation or failure in materials if they exceed the material's strength.
What causes shearing force break?
Shear force causes materials to slide past each other in opposite directions, leading to a break when the applied force exceeds the material's shear strength. Shearing force can result from various factors such as bending, cutting, or stretching of the material beyond its limit, causing fractures across the material.
Why would it be incorrect to refer to shear strength in g or kg?
It would be incorrect to refer to shear strength in grams or kilograms because shear strength is a measure of force per unit area (e.g., N/m^2 or Pa), not a measure of mass. Shear strength is a material property that quantifies how resistant a material is to shearing forces.
What do you actually measure for calculation of average value of a particular wave?
The answer depends on what characteristic of the wave you want to measure: its periodicity, its strength, etc.
How is the NFL Strength of Victory calculation determined and what impact does it have on team rankings and playoff seeding?
The NFL Strength of Victory calculation is determined by adding up the combined winning percentages of the teams a particular team has defeated. This metric is used to measure the quality of a team's wins. A higher Strength of Victory can positively impact a team's ranking and playoff seeding, as it demonstrates that the team has defeated opponents with better records. Teams with a higher Strength of Victory may have an advantage in tiebreaker scenarios for playoff seeding.
Strength of gravity units?
Classic calculation for force of gravity (f) between two masses is: f = (G*m1*m2) / d2 and the units are newtons.
How do you calculate pipe schedule?

What are the three types of stress in plates?
The three types of stress in plates are tensile stress (stretching), compressive stress (compressing), and shear stress (sliding or tearing). These stresses can cause deformation or failure in the material if they exceed its strength.
