What is the cross section formed by a plane that contains a vertical line?

Answer Expert Verified The cross section formed by a plane that contains a vertical line of symmetry for a tetrahedron is a Triangle. A tetrahedron also a triangular pyramid, is a polyhedron composed of four triangular faces, six straight edges, and four vertex corners.

Against this background, what is the shape of the cross section formed?

A cross section is the shape we get when cutting straight through an object. The cross section of this object is a triangle. It is like a view into the inside of something made by cutting through it. This is a cross-section of a piece of celery.

With that knowledge in mind, what shape will the vertical cross section of a cylinder be?

Cross-section Examples
The vertical cross-section of a cylinder is a rectangle, and the horizontal cross-section is a circle.

Subsequently, question is, what shape is the cross section formed by the intersection of a cone and a plane parallel to the base of the cone?

Circle. A circle is formed when the plane is parallel to the base of the cone.

What is a specific resistance?

Specific resistance is defined as the resistance offered per unit length and unit cross-sectional area when a known amount of voltage is applied.

What is the cross sectional area of a wire?

The cross-sectional area of the wire is the area of a circle of radius r: A=πr2=π(d2)2, where d is the diameter of the wire.

How do you calculate a cross section?

Cross-Sectional Area of a Rectangular Solid
The volume of any rectangular solid, including a cube, is the area of its base (length times width) multiplied by its height: V = l × w × h. Therefore, if a cross section is parallel to the top or bottom of the solid, the area of the cross-section is l × w.

How do I calculate resistance?

If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.

What is effective resistance between A and B?

therefore the effective resistance between A and B is 10Ω

How do you find the radius?

Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet. You can also use the circumference and radius equation.

What is cross section of a cylinder?

The cross-sectional area of a cylinder is equal to the area of a circle if cut parallel to the circular base. The cross-sectional area is the area of a two-dimensional shape that is obtained when a three-dimensional object - such as a cylinder - is sliced perpendicular to some specified axis at a point.

Are resistance and current directly proportional?

In the first version of the formula, I = V/R, Ohm's Law tells us that the electrical current in a circuit can be calculated by dividing the voltage by the resistance. In other words, the current is directly proportional to the voltage and inversely proportional to the resistance.

Does cross sectional area affect current?

Current is the change in charge over the change in time. Resistance is proportional to resistivity and length, and inversely proportional to cross sectional area.

What is the effective resistance?

However, if you had a huge and complicated circuit with many resistors, then the effective resistance is the total resistance of the circuit. Effective resistance is usually measured between 2 points. In the figure above, the effective resistance is generally defined as the total resistance across the battery.

What does not affect a material's resistance?

Length and area affect resistance as well as type of material expressed with . Temperature does not affect resistance.

How is current related to resistance?

The relationship between current, voltage and resistance is expressed by Ohm's Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant.

What is the formula of effective resistance?

For a circuit with resistances R1 and R2 in series or in parallel as in Figure 2, the effective resistance can be calculated by using the following rules. Rab = R1 + R2. Proof. Let Iab be the current from a to b.

What is the difference between cross sectional area and surface area?

Area is somewhat that is occupied by an object when it is resting on asurface i.e area is the space which isused by the object. Whereas cross-sectional area is an area which we obtain when the same object is cut into two pieces. The area of that perticular cross section is know ascross sectional area.

How do you simplify a circuit?

Strategy for simplifying a resistor network
  1. Begin as far away as possible from the circuit location in question.
  2. Replace series or parallel resistors with their equivalent resistor.
  3. Continue, moving left until a single equivalent resistor represents the entire resistor network.

Does diameter affect resistance?

As we know that resistance of a wire is inversely proportional to the square of its diameter. Thus when the diameter of a wire is doubled (made 2 times), its resistance becomes one-fourth (1/4), and if the diameter of a wire is halved (made 1/2), then its resistance becomes four times (4 times).

How does the cross-sectional area affect resistance?

More collisions mean more resistance. Second, the cross-sectional area of the wires will affect the amount of resistance. Wider wires have a greater cross-sectional area. In the same manner, the wider the wire, the less resistance that there will be to the flow of electric charge.

What 3 dimensional shape can have a cross section that is a hexagon?

The maximum number of "sides" of a cross section equals the number of faces (surfaces) of the solid. Since the rectangular prism shown above has 6 faces, a cross section of that solid may have at most 6 sides. So a hexagon (6 sided) cross section is possible, but an octagon (8 sided) cross section is not possible.

How do you figure out a diameter?

The radius is the length from the center of a circle to the edge. Therefore, if you know the radius, multiply it by two to determine the diameter (diameter = 2 x radius).

What is current formula?

Current is usually denoted by the symbol I. Ohm's law relates the current flowing through a conductor to the voltage V and resistance R; that is, V = IR. An alternative statement of Ohm's law is I = V/R.

What is resistance measured in?

Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.

What is the formula for parallel resistance?

The sum of the currents through each path is equal to the total current that flows from the source. You can find total resistance in a Parallel circuit with the following formula: 1/Rt = 1/R1 + 1/R2 + 1/R3 + If one of the parallel paths is broken, current will continue to flow in all the other paths.

How do you calculate cross sectional resistance?

The resistance R of a cylinder of length L and cross-sectional area A is R=ρLA R = ρ L A , where ρ is the resistivity of the material.
