The correct answer is "প্রক্সিমা সেন্টারাই" which means "Proxima Centauri" in English. Proxima Centauri is the closest star to Earth after the Sun and is located in the Alpha Centauri star system. It is a red dwarf star and is approximately 4.24 light-years away from Earth.

It takes approximately 1.5 seconds for light to travel from Earth to the Moon.

The correct answer is that the gravitational force of the black hole is very strong. This strong gravitational force prevents light from escaping, hence it cannot emit any light. The other options mentioned, such as its mass or the presence of dust particles, are not relevant to the inability of light to escape from a black hole.

The question asks when the phenomenon of "tejokatal" (a type of eclipse) occurs for the moon and the sun. The correct answer is "সবগুলো" which means "all of the above". This implies that the occurrence of "tejokatal" is influenced by all the mentioned factors, including when the moon and the sun are positioned on the same side of the earth, during "amabasya" (new moon), and due to the combined gravitational effect of the moon and the sun.

The correct answer is "ক্রোনোমিটার" because it is a device used to measure angular velocity or rotational speed. It is commonly used in navigation and aviation to measure the speed of a moving object, such as an aircraft or a ship. The other options, "কম্পাস", "সিসমোগ্রাফ", and "সেক্সট্যান্ট", are not related to measuring angular velocity or rotational speed.

Hipparchus is considered the father of astronomy because he made significant contributions to the field. He developed a comprehensive system for describing and predicting the motion of celestial bodies, including the sun, moon, and planets. He also created the first known star catalog, which included the positions and brightness of over 850 stars. Hipparchus' work laid the foundation for future astronomers and greatly advanced our understanding of the universe.

The question is asking which phase of the moon is not visible during a solar eclipse. The options given are "on the full moon day," "on the new moon day," and "on both full moon and new moon days." A solar eclipse occurs when the moon passes between the sun and the earth, blocking the sun's light. During a solar eclipse, the moon is in its new moon phase, which means it is not visible in the sky. Therefore, the correct answer is "on the new moon day."

The correct answer is ০.০০০০২%. This is the correct answer because it is the option with the smallest percentage value, indicating the smallest amount of methane in the air.

The question asks for the first communication satellite that was used for commercial purposes. The correct answer is "Early Bird Hall" because it was the first satellite to be used for commercial telecommunications. Venera 3 and Galileo are not relevant to the question as they were not used for commercial purposes.

The given options are related to different phenomena. "দিবা রাত্রির হ্রাস বৃদ্ধি" translates to "increase in the duration of daylight and decrease in the duration of nighttime." This phenomenon is known as the "increase in daylight hours" and is a natural occurrence due to the tilt of the Earth's axis. It is not caused by any form of motion or force, so it does not fall under the category of "আহ্নিক গতির ফলে ঘটে না" (not caused by mechanical motion).

The mesosphere is the layer of the atmosphere above the stratosphere and below the thermosphere. It is located approximately 50 to 85 kilometers above the Earth's surface. The temperature in the mesosphere decreases with increasing altitude, reaching its lowest point around -90 degrees Celsius. Therefore, the mesosphere has the lowest temperature among the given options.

The answer is "এলান হেল ও টমাস বপ" because they are the only two names that appear in both the first and last lines. The other two names, কাউরু ইকিয়া ও ডাকিং ঝাং, and কাউরু ঝাং ও ইকিয়া ডাকিং, only appear in the middle lines. Therefore, the correct answer is "এলান হেল ও টমাস বপ".

The ultimate fate of the universe is not written by Stephen Hawking.

The correct answer is "রোমান কৃষি দেবতার নামে". This is because the question asks for the name given to the planet Saturn. The other options do not correspond to the naming of the planet Saturn, but instead refer to a Roman commercial deity, a Roman sea deity, and a Roman war deity.

There are 181 lines of latitude in geography. Latitude lines are imaginary lines that run horizontally around the Earth, measuring the distance north or south of the equator. The equator is the starting point for measuring latitude, and there are 90 lines of latitude north of the equator and 90 lines of latitude south of the equator, making a total of 181 lines of latitude.

The Tropic of Capricorn is located at 23.5° south. This means that it is 23.5 degrees south of the equator. The Tropic of Capricorn is one of the five major circles of latitude that mark maps of the Earth. It is the southernmost point at which the sun can be directly overhead. The Tropic of Capricorn passes through several countries including Australia, Chile, Brazil, and South Africa.

The correct answer is "ম্যাজিলানিক ক্লাউডস" because it is the closest galaxy to the Milky Way. The other options mentioned, such as "স্বর্গ গঙ্গা" and "অ্যান্ড্রোমিডা," are not the closest galaxies to the Milky Way.

The question asks about the indication given by a barometer regarding the increase in height of clouds. The correct answer, "বৃষ্টির সম্ভাবনা" (possibility of rain), suggests that an increase in height of clouds is an indication of the possibility of rain.

The correct answer is পিথাগোরাস. পিথাগোরাস একজন প্রাচীন গ্রীক গণিতবিদ ছিলেন যিনি পিথাগোরাসের উপপাদ্য নির্দেশ করেন। তিনি পৃথিবীর আকার গোল ধারণার প্রথম প্রবর্তক হিসাবে পরিচিত। পিথাগোরাসের উপপাদ্য অনুসারে সুর্য ও চাঁদ পৃথিবীর সমান্তরালে ঘুরে থাকে এবং পৃথিবী স্থানাংক অক্ষ দিয়ে ঘুরে থাকে।
