Differences between system software and application software:
| System software | Application software |
| System software supports and manages computer system and interacts with other computer resources. |
Software that is designed for end users is known as application software. |
| It is designed to operate computer hardware devices. | Application software cannot control hardware devices. |
| System software provides a platform for application software to run in its environment and it controls the whole machine. | It performs in an environment provided by system software... |

Usage of java and html in web application:
Java belongs to the fifth generation software.
- The software that was developed approximately after the year 1990 is represented as the fifth generation software.
- Java is an object oriented
programming language designed and developed after 1990.- Java is an easy, secure, and platform-independent language that can be run on any computer.
- Structured design is based on the task (functions).
- It deals with the data and function separately.
- Object oriented design breaks the tasks into objects, and it is based on the object.
- It groups the data and functions together as objects which the real world object...

Explanation of Solution
Cloud computing services:
- Cloud computing is a type of computing that relies on computer resources sharing rather than the application running on local computing devices such as servers, computers, tablet, and Smart phones.
- In a cloud computing the cloud is used as a symbol for the internet, it means that the cloud computing is a type of internet based computing.
- There are three types of service categories available in cloud computing:
- The hardware-based service is categorized as “Infrastructure-as-a-Service”.
- The software-based service is categorized as “Software-as-a-Service”.
- The application and interface development based service is categorized as “Platform-as-a-Service”...

I want to ask someone who has experiences in writing physics based simulation software. For context I am building a game engine, and want to implement physics simulation. There are a few approaches that I managed to find, but would like to know what are other approaches to doing physics simulation entry points from scenes, would you be able to visually draw me a few approaches (like 3 approaces)?When I say entry point to the actual physics simulation. An example of this is when the user presses the play button in the editor, it starts and initiates the physics system. Applying all of the global physics settings parameters that gets applied to that scene.Here is the use-case, I am looking for. If you have two scenes, and select scene 1. You press the play button. The physics simulation starts. When that physics simulation starts, you are also having to update the physics through some physics dedicated delta time because physics needs to happen faster update frequency.To elaborate, what…

The agent can move on the grid horizontally and vertically, one square at atime (each step has a cost of one). No step may be made into a forbidden crossed area. Inthe case of ties, break it using up, left, right, and down.(a) Draw the search tree in a greedy search. Manhattan distance should be used as theheuristic function. That is, h(n) for any node n is the Manhattan distance from nto G. The Manhattan distance between two points is the distance in the x-directionplus the distance in the y-direction. It corresponds to the distance traveled along citystreets arranged in a grid. For example, the Manhattan distance between G and S is4.
