Force is only acting on x axis so y component is actually 0

How do you find the constant of proportionality?
K=Constant of proportionalityF=Force measured in N∆L= Total lengthK=F/∆L
How do you calculate unknown angles?
You use the information you're given, along with the rules, equations and formulas you know that relate the given information to the unknown angles, to find the angles.
How do you find width in meters?
. . . using a metre stick, measuring tape, or a measuring wheel . . . or one of the preceding along with a laser pointer, a protractor, and the tangent button on your calculator.
How do you find AC in the triangle ABC?
Use the information you're given and didn't mention in the question, along with all the formulas and equations you know that talk about the relationship among parts of triangles, to calculate the unknown numbers from the known numbers.
What does PDE mean?
In mathematics, a PDE is a Partial Differential Equation. To partially differentiate an equation, read below: Suppose you have a function f(x,y) and suppose you want to partially differentiate it w.r.t. x then you consider y as a constant and find d/dx(f(x,y)). Eg. - Let f(x,y)=xy+x+y then on partially differentiating f(x,y) w.r.t. x - d/dx(f(x,y)) = d/dx(xy) + d/dx(x) + d/dx(y) = y(d/dx(x)) + 1 + 0 (as y is constant) = y +1 Some application(s) of partial differential equations that I know - 1. Find the centre of a conic: Suppose you have a curve as a function of x and y, say f(x,y). Then to find its centre - -> Partially differentiate f(x,y) w.r.t. x. Let the equation obtained be e1. -> Partially differentiate f(x,y) w.r.t. y. Let the equation obtained be e2. Solve e1 and e2 to get (x,y) which is the centre of the curve. 2. To find the (conservative) force acting on an object if its Potential energy is given as a function of distance: -> Let the potential energy function be U(x,y). -> To find the force acting on object in x-direction, find minus(partial derivative of U(x,y) w.r.t. x). -> Same method to find force acting on the object in y-direction. -> Only works for conservative force.
