A rectangle with 4 right angles and all sides the same length?
Such a figure is called a square. Actually only one right angle is enough to force the the other angles to be right, and if three sides are equal, that forces all sides in such a figure to be equal. Exercise: Prove that any 4-sided figure( called a quadrilateral in math books) with three equal sides and one right angle is a square.
What is the Practical application of law of polygon forces?
The practical application of the law of polygon forces, also known as the principle of vector addition, is crucial in engineering and physics. It is used to determine the resultant force acting on an object when multiple forces are applied simultaneously. This principle helps in analyzing the equilibrium or motion of structures, machines, and systems by calculating the net force and direction. Understanding the law of polygon forces allows engineers to design stable and efficient structures by ensuring forces are properly balanced and distributed.
When a ramp is at a angle of 10.5 degrees what will be the applied force?
The applied force will depend on the required force, and the angle to the ramp (or the horizontal) at which the force is applied.
How many acres is the Air Force Academy?
The grounds of the Air Force Academy cover 18,000 acres
Can a cuboid slide and roll?
It can slide if there is enough force to overcome static friction. Similarly, it can roll if the force is great enough to impart a sufficiently large turning moment (and maintain it).
Explain why the polygon of forces must close when a body is in equilibrium?
The answer is in the definition: polygon of forces(plural polygons of forces) # (mechanics) A polygonal figure the sides of which are vectors representing several forces acting simultaneously upon one point, so that the vector necessary to make the figure closed is the resultant of those forces.
Is force always positive in physics?
In physics, force can be positive or negative. Positive force indicates a push or pull in a certain direction, while negative force indicates a push or pull in the opposite direction.
Which to components must be used to describe a force?
To describe a force, you need to specify both its magnitude and its direction. The magnitude indicates how strong the force is, while the direction indicates the way in which the force is acting.
What is the direction of the electric force on charge a in the figure?
The direction of the electric force on charge a in the figure is towards the right.
What is meant by an electromotive force of 12V?
An electromotive force (EMF) of 12V represents the electrical potential difference or voltage that can drive current through a circuit. It indicates the energy per unit charge supplied by a voltage source to move charges around a closed circuit.

How is pressure calculated in a closed system?
Pressure in a closed system is calculated by dividing the force applied on the system by the area over which the force is distributed. This formula is known as pressure force/area.
A closed system in which the net external force on the system is zero is a what?
A closed system in which the net external force is zero is in mechanical equilibrium.
How can I calculate water pressure in a closed system?
To calculate water pressure in a closed system, you can use the formula: Pressure Force/Area. This means that pressure is equal to the force exerted on the water divided by the area over which the force is applied. By knowing the force and the area, you can calculate the water pressure in the closed system.

What is a regular n-gon?
The term n-gon, where n is the number of the polygon's sides, also it could be used to name a polygon. For example, a polygon with 15 sides is a 15- gon.
