What is the value of k in electrostatics?
The symbol k is a proportionality constant known as the Coulomb’s law constant. The value of this constant is dependent upon the medium that the charged objects are immersed in. In the case of air, the value is approximately 9.0 x 109 N • m2 / C2.
What is K value in Coulomb’s law?
k is a constant of proportionality known as the Coulomb constant, having the value 9 x 109 N.m2 / C2 in a vacuum. …

Is K bigger than M? What does “K” or “M” behind numbers mean? On the Internet, 1K is used to represent 1 thousand and 10K is used to represent 10 thousand, similarly, 1M is used to represent 1 million. You must have understood this thing easily because “M” means Million, so “M” would be used for million. How many real solutions are there if the value of K?The answers that you found (for k) are when the discriminant equal 0 (b^2-4ac=0) — which means that the function has only one solution. How do you find the value of K on a graph?1 Answer. The area under the curve of f(x) is 1 by the definition of a density function. So, calculate the area under the curve of f(x), and then set it equal to 1 and solve for K. What are the values of A and B 29 21 20? rule is: 21/20=20/a=29/b; 2. 21/20=20/a, ⇒ a=400/21; 3. How do you know when a function is continuous? Your pre-calculus teacher will tell you that three things have to be true for a function to be continuous at some value c in its domain: f(c) must be defined. The function must exist at an x value (c), which means you can’t have a hole in the function (such as a 0 in the denominator). What are the values of M and B?The m variable is the slope of the line and controls its ‘steepness’. A positive value has the slope going up to the right. A negative slope goes down to the right. The b variable is the y intercept – the point where the line crosses the y axis. Is both continuous and differentiable?When a function is differentiable it is also continuous. But a function can be continuous but not differentiable. For example the absolute value function is actually continuous (though not differentiable) at x=0. What is differentiability and continuity? We see that if a function is differentiable at a point, then it must be continuous at that point. There are connections between continuity and differentiability. Differentiability Implies Continuity If is a differentiable function at , then is continuous at . If is not continuous at , then is not differentiable at .
