Internet uses:
- Packet switching: This is a method of transmitting data over a network by breaking it into small packets and sending them individually to their destination. The packets are then reassembled at the receiving end. This is the primary method used in the internet for data transmission.
- Circuit switching: This is a method of establishing a dedicated communication path between two parties before any data transmission takes place. It is commonly used in traditional telephone networks, where a circuit is established for the duration of the call. However, it is not commonly used in the internet.
- Telephone switching: This refers to the process of connecting telephone calls between different telephone lines. It involves the use of switches to route calls from the originating telephone line to the destination line. While the internet can support voice communication, it does not rely on traditional telephone switching methods.
- Telex switching: Telex was a telegraphy network used for sending text-based messages between telex machines. It utilized circuit switching to establish a dedicated connection between two machines. However, telex networks have largely been replaced by more modern and efficient communication methods, including the internet.
In conclusion, the primary method used in the internet for data transmission is packet switching, while circuit switching, telephone switching, and telex switching are used in other communication networks but are not commonly used in the internet.

Learning is effective in an environment that is emotionally positive and satisfying to learners. Any learner who is emotionally unstable may not be able to learn anything. The teacher must make the environment conducive for students to study and learn efficiently.
Errors made by the students do not indicate that no learning has taken place. Instead, they are the windows through which a teacher can understand the thought process of the students.
Learning is affected by emotional factors at any stage. Emotions change over time as the child matures, and in response to changing environmental interactions. The kind of learning that takes place at different emotional levels also differs.

Assessment for Learning, also known as formative assessment, is a type of assessment that occurs during the learning process to provide feedback to both the teacher and the student about understanding, progress, and areas needing improvement.

Key Points

• A teacher uses various methods, such as observations, questioning, and informal assessments, to gather information about student understanding during laboratory activities is an example of Assessment for learning.
• Assessment for Learning allows the teacher to identify and address any misconceptions or misunderstandings that may arise during these activities.
• By providing timely feedback and clarification, the teacher helps students develop a deeper understanding of scientific principles.

Hence, we can conclude that the correct answer is Assessment for Learning.

Upthrust = apparent loss of weight of object = weight in air - weight in liquid.

weight in air= W
Upthrust ,U= W/4
weight in liquid = weight in air- Upthrust
= W - W/4
=3W/4

 

Because the momentum is the force created by the mass and velocity of a body for example if a table tennis ball hit you it will not hurt because it have lesser mass and lesser velocity and if a cricket ball hits you it will hurt because the cricket ball have more mass and velocity. so by this we can say that the pickup truck travelling down the highway will have greater momentum as it have more mass than any other and also it have more velocity than others as it is in higher speed. I hope you learned something
