What are applications of basic proportionality theorem?
it can be used to draw tangents from a given point on a circle.
Find a formula for Poiseuilles Law given that the rate of flow is proportional to the fourth power of the radius and Use k as the proportionality constant?
Rate of flow varies as R^4 where R is the radius or Rate of flow = (k) x (R^4)
According to Charles's law for a fixed quantity of gas at constant pressure which of the given quantities is constant?
In Charles' Law, the mass is held constant which means that the pressure on the gas is constant.
What is an example of basic proportionality by theorem?
An example of basic proportionality would be Pythagoras' theorem, in which he states that for any right angle triangle its hypotenuse when squared is equal to the sum of its squared sides and is given by the formula of: a2+b2 = c2 whereas a and b are the sides of the right angle triangle with c being its hypotenuse or longest side.
Can a variable be a constant?
In algebra variables express a relationship within an equation and these are often used to give meaningful expressions to represent practical situations. These relationships often require a constant to be included in order to balance the equation turning the relationship from one of proportionality to one of equality. The variables themselves are only constant for a given set of conditions. i.e The voltage across a resistance of 60 ohms carrying a current of 4 amps will be 240v. (V= current x resistance). A separate constant is not needed in this case as the resistance is defined by the other two properties. In science one example of a constant that is thought to be variable is the speed of light, which for all practical purposes is considered to be constant but is thought to have changed gradually with time. I don't know what possible ways there are of verifying this.
