What is diff between sensor and transducers?
TRANSDUCER is a device converts one form of energy into other forms sensor it is device any form into electrical form my point of view ,all the sensors are transducers ,but all the transducers are not sensors
Does resistor is a negative coefficient of temperature?
Actually it depends on the material from which the resistor is made, well in general for all practical purposes we choose a material with positive temperature coefficient as we deliberately want to add a resistance to the circuit. But if we come across some resistors which are made up of materials like Glass, Ceramics, Semiconductors , have negative temperature coefficients (practically not used)
What is algebraic numbers?
An algebraic number is one that is a root to a non-zero polynomial, in one variable, whose coefficients are rational numbers.Equivalently, if the polynomial is multiplied by the LCM of the coefficients, the coefficients of the polynomial will all be integers.
When you have two linear equations how do you know when they are all real numbers?
The answer depends on what are meant to be real numbers! If all the coefficients are real and the matrix of coefficients is non-singular, then the value of each variable is real.
What is the difference between positive and negative temperature coefficient of resistance?
Negative temperature coefficient of resistance means that as the temperature of a piece of wire or a strip of semiconducting material increases, the electrical resistance of that material decreases.
What are the possible ranges of correlation coefficients?
The possible range of correlation coefficients depends on the type of correlation being measured. Here are the types for the most common correlation coefficients: Pearson Correlation Coefficient (r) Spearman's Rank Correlation Coefficient (ρ) Kendall's Rank Correlation Coefficient (τ) All of these correlation coefficients ranges from -1 to +1. In all the three cases, -1 represents negative correlation, 0 represents no correlation, and +1 represents positive correlation. It's important to note that correlation coefficients only measure the strength and direction of a linear relationship between variables. They do not capture non-linear relationships or establish causation. For better understanding of correlation analysis, you can get professional help from online platforms like SPSS-Tutor, Silverlake Consult, etc.
What is the importance of transducers?
A transducer is a device that converts a physical quantity into some other type of signal eg. sound to voltage, light to current, or vice versa
Why all the temperatures on kelvin scale are positive?
Temperatures on the Kelvin scale are always positive because it is based on absolute zero, the theoretical point at which particles have minimal motion. Since there is no negative temperature in terms of kinetic energy, temperatures on the Kelvin scale are always positive.
What is -4x 9x?
All we have to do is subtract the coefficients of the x terms. The solution is -4x.
Why the graph of a polynomial function with real coefficients must have a y intercept but no x intercept?
A polynomial function is defined for all x, ranging from minus infinity to plus infinity. Since it is defined for all x, it is defined for x = 0 and this is the point where it intersects the y-axis which is called the y-intercept. It is possible, with suitable choice of coefficients that the function is always positive or always negative. In either case it will not cross the x-axis so that there is no x-intercept. However, it is not true to say that all polynomial functions with real coefficients do not have an x-intercept. In fact all polynomials of odd order (linear, cubic, quintic etc) will have at least one x-intercept.
What do you mean by a function identically equal to zero?
A polynomial is identically equal to zero if and only if all of its coefficients are equal to zero. eg. The power series on the left is identically equal to zero, consequently all of its coefficients are equal to 0:
When can all the coefficient in a balanced equation represent volume ratios?
All coefficients in a balanced chemical equation can represent volume ratios only if all the substances involved are in the gas phase and at the same temperature and pressure. This is known as the ideal gas law assumption.
