Entrance Questions

Hello everyone!

I hope you’re all doing well. I wanted to take a moment to share an idea that I believe could enhance our community.

As many of you know, we have been using the bot @EUEETIPSCHANNELVIPBot to gather feedback and answer your questions. I appreciate all the inquiries you've sent my way, but it has become increasingly challenging for me to respond to each one individually.

To improve this process, I propose creating a new Telegram bot where you can ask questions—either anonymously or with your name attached. Once submitted, your questions will be sent for approval and, once approved, will be posted automatically in this channel. This way, everyone can contribute answers and support each other!

If you like this idea, please give a thumbs up! 👍🏼 👍🏼 Your feedback is important to me, and I look forward to hearing your thoughts.

Thank you!

I hope we will do some of the questions together one day. Until then practice these questions by your self.

Correction on 7th question. Bacteria don't have Nucleus since they are Prokaryotes so the answer must be Plasmid which plays a role in genetic exchange.

Requested by someone. I appreciate such kinds of members.

🌟 Hey everyone! 🌟

I’m thinking it would be beneficial for us to meet on a Telegram video chat at least once a week to practice some EUEE questions together. This way, we can support each other and enhance our learning experience!

If you’re interested in joining these practice sessions, please comment below with "Good idea!" If we can get at least 5 people on board, we can kick this off!

Looking forward to hearing from you all! 😊

Answer And explanation for above questions which are taken from Physics

1. B) Projectile motion
Explanation: Projectile motion involves the motion of an object in a curved path under the influence of gravity, like a ball thrown into the air.

2. B) Angular momentum
Explanation: Angular momentum is conserved in the absence of external torques in rotational motion, similar to the conservation of linear momentum in linear motion.

3. B) Elliptical
Explanation: Kepler's first law states that planets move in elliptical orbits around the Sun, with the Sun located at one of the foci of the ellipse.

4. A) Square of the distance between the objects
Explanation: The force of gravity between two objects is inversely proportional to the square of the distance between them, as described by Newton's law of universal gravitation.

5. D) Kepler's third law
Explanation: Kepler's third law describes the relationship between the orbital period and the average distance of a planet from the Sun.

6. B) Pressure
Explanation: Fluid statics deals with the study of fluids at rest and focuses on properties such as pressure and buoyancy.

7. B) Archimedes' Principle
Explanation: Archimedes' Principle states that the buoyant force on an object immersed in a fluid is equal to the weight of the fluid displaced by the object.

8. C) Pressure
Explanation: Hydraulic systems work based on the principle of transmitting pressure through a fluid to generate a force that can lift heavy objects.

9. A) Fluid dynamics
Explanation: Fluid dynamics is the branch of fluid mechanics that studies how fluids flow and the forces involved in their motion.

10. A) Directly proportional
Explanation: Pressure in a fluid is directly proportional to the depth of the fluid, as described by Pascal's principle.

11. A) Current can create a magnetic field
Explanation: The flow of electric current generates a magnetic field around the conductor, as observed in electromagnets.

12. B) Rate of change of magnetic field
Explanation: According to Faraday's law of electromagnetic induction, the induced emf in a circuit is directly proportional to the rate of change of the magnetic field through the circuit.

13. B) Increase voltage
Explanation: Transformers work based on electromagnetic induction to increase or decrease voltage levels in electrical circuits.

14. C) Between conductors and insulators
Explanation: Semiconductors have electrical conductivity between that of conductors and insulators and are essential in electronic devices.

15. C) To control current flow
Explanation: Diodes are semiconductor devices that allow current to flow in one direction and block it in the opposite direction, controlling the flow of current in a circuit.

16. D) Current gain
Explanation: Transistors can amplify or switch electronic signals based on their current gain, which is a measure of how much the transistor amplifies the input signal.

17. A) Silicon chip
Explanation: Integrated circuits are miniaturized electronic circuits made up of semiconductor components fabricated onto a small silicon chip.

18. A) Voltage levels
Explanation: Logic gates process input signals based on predefined logical functions related to voltage levels to generate output signals in digital circuits.

19. C) Agricultural practices
Explanation: Electronics are not commonly used in agricultural practices compared to fields like telecommunications, computing, and medical devices.

20. C) Through electronic components
Explanation: Logic circuits process input signals to generate output signals based on logical functions using electronic components like transistors, resistors, and capacitors.
