What is physical efficiency?
efficiancy in physics is always measured as ratio of output and input
Why is work output always less than work input?
Work output is always less than work input because some work is lost to friction and heat which is created in the process of physics.
When using a real machine to do work input work will always be?
Work output is always less than work input because some work is lost to friction and heat which is created in the process of physics.
What means work output divided by work input?
input force x input distance > output force x output distance -Novanet
What dose RF mean?
It depends on the context. In electronics, RF stands for Radio Frequency.
What is an RF input?
An RF (Radio Frequency) input is the technical term for a coaxial/antenna input on the back of a television. This input is often referred to as simply 'cable' or 'cable vision'.
What is rf in?
radio frequency input
Is coaxl input on tv HDMI?
The coaxial RF input on a HDTV will process a HD signal but it is not an HDMI input.
What RF levels are commonly considered to be an indication of sufficient analog video level at the RF input of a TV set?
0 to -5
How do you calculate gain of an inverting and non-inverting OP-Amp configuration?
gain in an op-amp is the output voltage divided by input voltage. for the inverting amplifier , gain(Av)=-(Rf/Ri) ,where Rf => resistance of the feedback path & Ri=> inverting input terminal resistance for the non-inverting amplifier , gain(Av)=(1+(Rf/Ri)) , where Rf => same & Ri=> non inverting input terminal resisance
What is efficiancy in physics?
efficiancy in physics is always measured as ratio of output and input
How can you tell if a sony High Definition tuner is built in?
If it is widescreen and has an antenna (RF) input.
Can you use an outdoor antenna with a flatscreen tv?
Yes, if it has an antenna input connector, (RF in).
Your HDTV does not have an hmdi input how should you connect your cable box to the tv?
In descending order of quality, Component, S-Connector then Video. The RF or antenna input is the poorest.
Formula of input work?
Work W = [r,R][f,F] =[rf -R.F, rF + Rf +RxF] r is distance, R is displacement and f a scalar force and F the vector force. Concepts in Physics are Quaternions, the sum of a sclar and vector.
What is physical efficiency?
efficiancy in physics is always measured as ratio of output and input
What is a rf scale?
An RF scale is a Representative Fraction (RF) Scale
