How the coefficient of viscosity of a liquid changes with temperature?
The coefficient of viscosity of liquids decreases with an increases in temperature.
What does it mean for variables to show correlation?
A positive correlation coefficient means that as the value of one variable increases, the value of the other variable increases; as one decreases the other decreases. A negative correlation coefficient indicates that as one variable increases, the other decreases, and vice-versa.
If a carbon resistor increases in temperature its resistance will?
This depends on the type of conductor. If the conductor has a positive coefficient the resistance will increase. If the conductor has a negative temperature coefficient the resistance will decrease.
What is the relationship between resistance and temperature?
• ntc 'negative temperature coefficient': its resistance decreases as the temperature increases• ptc 'positive temperature coefficient': its resistance increases as the temperature increases
does The strength of the correlation between two variables depend on the sign of the coefficient of correlation?
No, it depends upon the size of the coefficient of correlation: the closer to ±1 the stronger the correlation.When the correlation coefficient is positive, one variable increases as the other increases; when negative one increases as the other decreases.
What is the difference between PTC and NTC resistors?
positive temperature coefficient vs. negative temperature coefficient resistance increases or decreases with increase of temperature, respectively.
Why does the resistance of a semiconducting material decrease when the temperature increases?
The no of electrons in the conduction band increases when the temperature of the semiconductor material increases. therefore resistance decreases. This is also know as "Negative temperature coefficient"
When the correlation coefficient is negative?
The dependent variable has an inverse linear relationship with the dependent variable. When the dependent increases, the independent decreases, and conversely.
What happens to the speed of a wave if the frequency decreases and the waveleNgth increases?
If the frequency decreases and the wavelength increases, the speed of the wave remains constant. This is because the speed of a wave is determined by the medium it's traveling through, not by its frequency or wavelength.
Why internal resistance of the battery decreases as temperature increases?
R is inversely related to temperature T so as temperature increases resistance decreases. Specifically, R increases if the T coefficient is pos.(P.T.C) And decreases if T coefficient is neg. (N.T.C) Most conductors have P.T.C and most insulators have (N.T.C) . xept. like carbon. 1 of few conductors that has a N.T.C. But all can be found on a tablet. R.T.C / R mil-foot ,R, millimeter-meter and R.T.C @ 68*F
What is the connection between slope in a linear function and the a coefficient in a quadratic?
The slope of a linear function is the coefficient of the x term. The sign of this number will determine if the line increases as x increases, or decreases as x increases (slopes up or down). The magnitude of the slope determines how steep the line is (how fast it increases).The coefficient of the x2 term in a quadratic function will tell you similar characteristics of the parabola. The sign will tell you if the parabola opens up or down. The magnitude of the coefficient tells you how steeply the graph changes.
What happens to the graph as the coefficient increases?
Most graphs will become steeper as the coefficient increases.
