The correct Answer is:
To solve the given question, we need to analyze both the assertion and the reason provided. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "X-ray astronomy is possible only from satellites orbiting the earth." - This is true because X-rays from astronomical sources cannot penetrate the Earth's atmosphere. The atmosphere absorbs X-rays, preventing them from reaching ground-based telescopes. 2. **Understanding the Reason**: - The reason states that "Efficiency of X-ray telescopes is large as compared to any other telescope." - This statement is misleading. While X-ray telescopes are designed to be efficient in space, the efficiency comparison to other types of telescopes (like optical or radio telescopes) is not the reason why X-ray astronomy must be conducted from space. The primary reason is the absorption of X-rays by the atmosphere, not the efficiency of the telescopes. 3. **Conclusion**: - Since the assertion is correct (X-ray astronomy can only be done from space due to atmospheric absorption), but the reason is incorrect (it does not accurately explain why X-ray astronomy is conducted from space), we conclude that the assertion is true, and the reason is false. ### Final Answer: - The assertion is true, and the reason is false.

It is teming to think that all possible transituion are permissible and that an atomic spectrum series from the transition of an electron from any intial orbital to any other .However this is not so because a photon a photon has as intrinsic spin angular momentum of sqrt(2) h// 2pi corresponding to S = 1 although it has no charge and no rest mass On the other hand , an electron has got two typwe of agular momentum orbit angular momentum L = [sqrt(l(l+1))] h//2pi ,and spin angular momentum L_(1) = sqrt(s(s + 1)) h//2pi arising from orbital motion and spin motion of the electronn during any electton transition must compentum for the angular momentum carried away by the photon .To salary this condition the different between the azisition quantum number of teh orbital witjhin which the transition (l = 2) cannot make a transition into as x-orbital (l = 0) because the photon cannot carry away enough angular momentum The maximum orbital angular momentum of an electon with n = 5 is

An unmanned satellite A and a spacecraft B are orbiting around the earth in the same circular orbit as shown. The spacecraft is ahead of the satellite by some time. Let us consider that some technical problem has arisen in the satellite and the astronaut from B has made it correct. For this to be done docking of two ( A and B ) is required (in layman terms connecting A and B ). To achieve this, the rockets of A have been fired in forward direction and docking takes place as shown in the figure below: Take mass of the earth =5.98xx10^(24)kg Radius of the earth =6400 km Orbital radius =9600km Mass of satellite A=320 kg Mass of spacecraft =3200 kg Assume that initially spacecraft B leads satellite A by 100s , i.e., A arrives at any particle position after 100 s of B’s arrival. Based on the above information answer the following questions. To dock A and B in the above-described situation, one can use the rocket system of either one, i.e., either of A or of B . To accomplish docking in the minimum possible time which is the best way?
