# Can a vector have a component equal to zero?

## Can a vector have a component equal to zero?

Yes, a vector can have a component equal to zero and still have a nonzero magnitude.

What is Cartesian form of vector?

We know that = xi + yj. The vector , being the sum of the vectors and , is therefore. This formula, which expresses in terms of i, j, k, x, y and z, is called the Cartesian representation of the vector in three dimensions. We call x, y and z the components of. along the OX, OY and OZ axes respectively.

How do you find the z component of a force?

i, j, and k are unit vectors in the direction of x, y and z respectively.

1. dx=x2ˆ’x1.
2. dy=y2ˆ’y1.
3. dz=z2ˆ’z1.

### What is an example of a 3 dimensional?

Three dimensional In geometry, three-dimensional shapes are solid figures or objects or shapes that have three dimensions “ length, width, and height. A cube and cuboid are examples of three-dimensional objects, as they have length, width, and height.

Why is it called 3 dimensional?

Space has three dimensions because the length of a box is independent of its width or breadth. In the technical language of linear algebra, space is three-dimensional because every point in space can be described by a linear combination of three independent vectors.

What’s a three-dimensional triangle called?

The tetrahedron is the three-dimensional case of the more general concept of a Euclidean simplex, and may thus also be called a 3-simplex. In the case of a tetrahedron the base is a triangle (any of the four faces can be considered the base), so a tetrahedron is also known as a “triangular pyramid”.

#### What do you call a solid triangle?

In geometry, a solid that is made up of four triangular faces is called tetrahedron. Also, a pyramid that has its base, triangle in shape is called a triangular pyramid. See the diagram below to understand. Solid figures are those figures that have surface area and volume.

What objects are triangular prisms?

A triangular prism has two triangular bases and three rectangular sides and is a pentahedron because it has five faces. Camping tents, triangular roofs and “Toblerone” wrappers — chocolate candy bars — are examples of triangular prisms.

What does a triangular prism look like?

In geometry, a triangular prism is a three-sided prism; it is a polyhedron made of a triangular base, a translated copy, and 3 faces joining corresponding sides. A right triangular prism has rectangular sides, otherwise it is oblique. All cross-sections parallel to the base faces are the same triangle.

## What is another name for triangular prism?

What is another word for triangular prism?

polyhedron right triangular prism
three-sided prism uniform triangular prism
wedge

What is the difference between a rectangular prism and a triangular prism?

What is the difference between triangular prism and rectangular prism? A triangular prism has its bases in triangle shape and a rectangular prism has its bases in rectangle shape.

Which is the net of a triangular prism?

The net of a triangular prism consists of two triangles and three rectangles. The triangles are the bases of the prism and the rectangles are the lateral faces. The net of a rectangular prism consists of six rectangles. Both the bases and the lateral faces of this shape are rectangles.

### What is the net of a prism?

The net of a solid figure is formed when a solid figure is unfolded along its edges and its faces are laid out in a pattern in two dimensions. Nets of rectangular prisms are made up of rectangles and squares.

How do you draw a net for a triangular prism?

Constructing triangles given SSS

1. Draw the longest side using a ruler.
2. Open the pair of compasses until they are 5 cm wide. Use a ruler to measure it. Draw an arc from point H above the line.
3. Open the pair of compasses until they are 3 cm wide. Use a ruler to measure it.
4. Join the arc to the points H and J using a ruler.
