What is a visual object?

Visual Objects is an object-oriented computer programming language that is used to create computer programs that operate primarily under Windows. Although it can be used as a general-purpose programming tool, it is almost exclusively used to create database programs.

How are objects visible to our eyes?

(A) Light gets reflected from our eyes and makes the object visible. ... Hint : Our eyes absorb much of the light coming from the environment or a luminous source. For humans to be aware of the presence of light, the light waves have to get absorbed into our retina through the pupil.

What objects do you see Can you name at least 10 objects?


  • guitar.
  • table.
  • cellphone.
  • ball.
  • chair.
  • cabinet.
  • miror.
  • mug.

What is the basic to identify an object?

Objects around us are all kinds of objects and thus identifying them is important. ... Hence, we can identify the objects based on their shape, size, colour and texture.

How do you classify objects?

When objects are classified, they are simply put into a group with other similar objects. The classification systems used in biology are based on the similarities and differences in organisms. Without classification systems, scientists would have to talk about individuals and not groups.

What are the properties of objects?

4 The student will investigate and understand that the position, motion, and physical properties of an object can be described. Key concepts include a) colors of objects; b) shapes and forms of objects. Objects have properties that can be observed and described. Physical properties include size, shape, and texture.

What height will be returned by a tree with one node?

According to Wikipedia, The height of a tree is the length of the path from the root to the deepest node in the tree. A (rooted) tree with only one node (the root) has a height of zero (or one).

Can a tree node have two parents?

Yes, you can have nodes have both “children” and “parents”. However that is no longer a tree structured graph, so you will not be able to use a TreeModel – you must use a GraphLinksModel.

What is tree node?

A node is a structure which may contain a value or condition, or represent a separate data structure (which could be a tree of its own). Each node in a tree has zero or more child nodes, which are below it in the tree (by convention, trees are drawn growing downwards).

What is an example of a node?

Any system or device connected to a network is also called a node. For example, if a network connects a file server, five computers, and two printers, there are eight nodes on the network. Each device on the network has a network address, such as a MAC address, which uniquely identifies each device.

What is difference between tree and graph?

Graph is a non-linear data structure. Tree is a non-linear data structure. It is a collection of vertices/nodes and edges. ... But in case of binary trees every node can have at the most two child nodes.

Which is better tree or graph?

In a tree there exist only one path between any two vertices whereas a graph can have unidirectional and bidirectional paths between the nodes. In the tree, there is exactly one root node, and every child can have only one parent. As against, in a graph, there is no concept of the root node.

Is tree a graph?

In graph theory, a tree is an undirected graph in which any two vertices are connected by exactly one path, or equivalently a connected acyclic undirected graph. ... A polytree (or directed tree or oriented tree or singly connected network) is a directed acyclic graph (DAG) whose underlying undirected graph is a tree.

What is difference between linear and nonlinear data structure?

In a linear data structure, data elements are arranged in a linear order where each and every elements are attached to its previous and next adjacent. In a non-linear data structure, data elements are attached in hierarchically manner. ... In linear data structure, data elements can be traversed in a single run only.
