Lami's theorem states that for a system in equilibrium with three forces acting at a point, the magnitudes of these forces can be calculated using the formula: ( \frac{W}{\sin A} = \frac{P}{\sin B} = \frac{Q}{\sin C} ). Here, ( W ) is the unknown force and ( A, B, C ) are the angles opposite to the forces ( W, P, Q ) respectively. To calculate ( W ), rearrange the equation to ( W = P \cdot \frac{\sin A}{\sin B} ) or ( W = Q \cdot \frac{\sin A}{\sin C} ), depending on the known forces and angles. Ensure that the angles are measured in the same unit (degrees or radians) for accurate calculations.

What is the total displacement of a dog that runs north W meters to chase a ball and then runs W meters?
The total displacement of the dog can be calculated using the Pythagorean theorem. After running W meters north and then W meters east, the dog's path forms a right triangle where both legs are W meters. The total displacement is the hypotenuse, which is √(W² + W²) = √(2W²) = W√2. Thus, the total displacement of the dog is W√2 meters in a northeast direction.

What is the perimeter of a rectangle whose diagonal is 17.55 cm with an area of 109.35 square cm showing all work with answers please?
First define your variables and set up some equations. w= width of the rectangle. h= height. d= the diagonal. Our goal is to first solve for h and w so we can calculate perimeter. According to Pythagorean theorem, w^2 + h^2 = d^2 (we can do this because half of a rectangle is a right triangle). h^2 + w^2 = 17.55^2. Also, the length times width equals area (l x w=area). So, h x w =109.35 cm. Since you have 2 unknown variables and 2 equations, you can solve for the variables one at a time by using substitution. By manipulating the 2nd equation to isolate h, h= 109.35/w. Then, plug in your "h value" you just solved for into the 1st equation to get (109.35/w)^2 + w^2 = (17.55)^2. Simplifies to (11957.422/w^2) + w^2 = 308.0025. Manipulate and solve.
Ow do you calculate amperage with watts and volts?
You can calculate amperage (A) using the formula A = W / V, where W is the power in watts and V is the voltage. Simply divide the power in watts by the voltage to find the amperage.
What does barbier's theorem say about a curve of constant width?
I think you want to ask What does Barbiers Theorem says about a figure of constant width. Such a nice theorem establishes that if you have a compact figure C in the plane, that is closed and bounded, and C has constant width w, then the perimeter of C is "pi times w"
What is the proof of the work-energy theorem?
The work-energy theorem states that the work done on an object is equal to the change in its kinetic energy. Mathematically, this can be expressed as W KE, where W is the work done on the object and KE is the change in its kinetic energy. The proof of this theorem involves applying the principles of work and energy conservation in physics.
What is an equation for work energy theorem?
The work-energy theorem states that the work done on an object is equal to the change in its kinetic energy. Mathematically, the equation can be written as W = ΔKE, where W is the work done on the object and ΔKE is the change in its kinetic energy.
What is the formula for the width of a 3-D shape?
There is no single formula for the width of any arbitrary shape. If however, you already have two points that define that width, then you can calculate the distance between them with simple Pythagorean theorem: w = [Δx2 + Δy2 + Δz2]1/2

How do you find the area of a rectangle if you only know the width and the diagonal?
Suppose the width is W and the diagonal is D.Then, by Pythagoras's theorem, the length, L, is given by L = sqrt(D^2 - W^2).And then, area = L*W.
How do you calculate win- lose?
To calculate win-lose, add the wins and the losses and divide the sum into the wins to calculate percentage of wins or divide into the losses to calculate the percentage of losses: W + L = Total; W ÷ Total = W%; L ÷ Total = L%: example: 12 W + 8 L = 20; 12W ÷ 20 = .60 or 60% wins; 8L ÷ 20 = .40 or 40% losses
How do you calculate power?
Power can be calculated using the formula: Power (P) = Work (W) / Time (t). It is the rate at which work is done or the amount of energy transferred per unit time. The SI unit of power is the watt (W).
