Do linear graphs represent proportional relationships?
Do all linear graphs have proportional relationship
Do all linear equations need to be proportional?
No.A directly proportional graph has an equation of the form y = mx. It always passes through the origin.A linear graph will have an equation in the from y = mx + c. This has a y-intercept at (0, c). It doesn't pass through the origin unless c = 0. The directly proportional graph is a special case of a linear graph.
What is Linear and Non-Linear Relationships?
A linear relationship means that the slope of the line is proportional, which means that the line is straight. In contrast to the linear realtionship, the non-linear relationship's slope is not proportional and the line will curved and not straight. Formula of calculating the slope is the difference of y divided by the difference of x.
Which are linear system and non linear system?
Linear system has a proportional slope, which gives the system a straight line. And, a non-linear system has a non-proportional slope, which is represented by a non-straight line (usually a curved one). Feel free to edit if you think this is not to the point.
What is the difference between linear and non linear scales?
A linear scale is a scale with equal divisions for equal vales, for example a ruler. A non linear scale is where the relationship between the variables is not directly proportional.
How can you tell something is a linear function?
A function is linear if one variable is directly proportional to the other.
Why ohms law applicable only linear resister?
because they have a proportional relation
What is mercury used for in a thermometer?
The thermal expansion of mercury is proportional and linear to temperature.
Are linear relationships proportional?
A relationship that occurs when variable quantities are directly proportional to one another. A linear relationship can be represented on a graph as a STRAIGHT LINE. Linear relationships always follow the formula: y=mx+b where y is the value of the y-coordinate, where my is the slope of the line, where x is the value of the x-coordinate, and b is the y-intercept
What are the examples of non linear devices?
"A device for which the output is, within a given dynamic range, linearly proportional to the input" e.g. a spring scale is linear device for measuring weight.
Is transistor a linear or non linear device?
we will operate transistor mainly in 4 regions..namely active ,cutoff,saturation and pinch off region depending on the type of biasing. if it is under active region then transistor is a linear device.. linearity in the sense if the output is proportional to input then it is said to be linear.
What happens to the volume of an object as its surface area increases?
In general, the volume will also increase. If the shape remains the same, the volume will increase faster than the surface area. Specifically, the surface area is proportional to the square of an object's diameter (or any other linear measurement), while the volume is proportional to the cube of any linear measurement.
What is Linear system in electronics?
A linear electronic device is one where output is linearly proportional, in some way, to input. An example is an amplifier. A non-linear device is one where the input drives the circuit into some kind of saturation mode. An example is a switch, such as is used in TTL IC's.
If a solid is enlarged with a linear scale factor of 2 how many times larger would the volume of the new volme be?
Volume of a solid is proportional to the cube (3rd power) of its linear dimensions.When linear dimensions are doubled, volume increases by a factor of (2)3 = 8 times.
Is zener diode a linear device?
Zener diode is not a linear device... it is non-linear one. Since linear devices are those devices which have linear characteristics(V-I CHAR.), or follows the Ohm's law i.e. voltage is directly proportional to current. but in case of Zener diode ohm's law fails down. the V-I char. in both forward biased & reverse biased condition is non-linear. So. Zener diode is non-linear device
What is the different between linear and nonlinear pulse code modulation?
The difference between linear and non-linear PCM is LPCM represents sample amplitudes on a linear scale. LPCM specifies that the values stored are proportional to the amplitudes, rather than representing say the logarithm of the amplitude or being related in some other manner. While non-linear each step size may vary in amplitude.
If the dimensions of a triangular prism is doubled what happens to the volume?
Volume is proportional to the cube of the linear dimensions.Double the dimensions ===> volume is multiplied by (2)3 = 8 .
