Earthquake Alarm working model explanation Conductive Strips: Positioned so that the ball /Nut can complete the circuit by touching both simultaneously. Circuit Completion: During an earthquake, the ball /Nut moves and touches the strips, closing the circuit and triggering the buzzer. An earthquake alarm project, also known as an earthquake early warning system, is a system that detects the start of an earthquake and issues a warning to nearby areas before significant ground shaking occurs. The goal is to give people time to prepare. The basic principle of work and warning earthquake detector with a vibration sensor this is when an earthquake occurs or when the dynamo (earthquake simulator) is started, the resulting vibrations cause movement of the pendulum. This pendulum movement is what will trigger the sound of the bell.

Ans: সাদা কাগজ টা Tracing paper ( ট্রেসিং পেপার ) | একটি পিনহোল ক্যামেরার ট্রেসিং পেপার অংশটিকে একটি বড় বাক্সে আবদ্ধ করার উদ্দেশ্য হল ট্রেসিং পেপারের (অস্বচ্ছ স্ক্রীন) চারপাশকে অন্ধকার করা যাতে এটিতে তৈরি চিত্রটি এমনকি দিনের আলোতেও পরিষ্কারভাবে দেখা যায়।

Black paper or any other material that is dark and non-reflective is often used inside a pinhole camera to minimize reflections of light within the camera. The purpose of using black paper inside the camera is to absorb any light that may enter the camera through the pinhole and prevent it from bouncing around inside the camera, which could cause unwanted light to be scattered and reduce image clarity.

f the interior of the camera had a mirror-like finish, maybe the effect could look quite interesting - inverted doublings of parts of the image, that would look similar to a double exposure / kaleidoscope image. N.B: But you can also try other colour paper. Best of luck .. if you need any help please write on my facebook page or telegrame channel.

Most welcome 😊

Thanks
