If ‘X’ corresponds to a tunnel diode and ‘Y’ to an avalanche diode, then__________

If ‘X’ corresponds to a tunnel diode and ‘Y’ to an avalanche diode, then__________ Correct Answer X operates in forward bias and Y operates in reverse bias

In forward bias, negative resistance helps for tunnel diode to operate. Here, the current decreases with increase in voltage. If they are used in reverse bias, they are called as back diodes. Avalanche diode operates in reverse bias at breakdown region.

It is desired to freeze 10,000 loaves of bread each weighing 0.75 kg from an initial room temperature of 18°C to a final temperature of -18°C. The bread-freezing operation is to be carried out in an air-blast freezing tunnel. It is found that the fan motors are rated at a total of 80 horsepower and measurements suggest that they are operating at around 90% of their rating, under which conditions their manufacturer’s data claims a motor efficiency of 86%. If 1 ton of refrigeration is 3.52 kW, estimate the maximum refrigeration load imposed by this freezing installation assuming that fans and motors are all within the freezing tunnel insulation and the heat-loss rate from the tunnel to the ambient air has been found to be 6.3 kW. Extraction rate from freezing bread (maximum) = 104 kW

একটি ট্রেনের স্থির অবস্থায় দৈর্ঘ্য হলো 100 m। এটি অতি উচ্চ বেগে 80m দৈর্ঘ্যের একটি সুড়ঙ্গের মধ্য দিয়ে যায়। সুড়ঙ্গের দুই প্রান্তে অবস্থিত পর্যবেক্ষকরা লক্ষ করেন যে, একটি মুহূর্তে ট্রেনটির দৈর্ঘ্য ঠিক সুড়ঙ্গের দৈর্ঘ্যের সমান হয়। c এর এককে ট্রেন এর বেগ কত? (A train has a rest length of 100 m. Traveling at a very high velocity, it goes through a tunnel of length 80 m. Observers located at both ends of the tunnel note that at one instant the train appears to exactly fit within the tunnel. What is the velocity of the train expressed in units of c?)
A train approaches a tunnel AB. Inside the tunnel is a cat located at a point that is $$\frac{3}{8}$$ of the distance AB measured from the entrance A. When the train whistles, that cat runs. If the cat moves to the entrance A of the tunnel, the train catches the cat exactly at the entrance. If the cat moves to the exit B, the train catches the cat at exactly the exit. The ratio of the speed of the train to that of the cat is of the order :
