India is the world's largest milk producer,with 22 percent of global production. Brazil is the world's largest coffee producer,supplying around a third of the world's coffee.

A2 Vishnu Ravi, Bachelor of Engineeringin Aerospace and Aeronautical Engineering, Indian Institute of Technology,Madras (IITM) (Graduated 2015)Jun 7 If aplane flew too high, it can run into all sorts of dangers that threaten thepassengers and the plane itself. High-Flying Hazards: When a big ol' plane climbs tocrazy altitudes, the air starts getting thinner and less dense. That means the air passing over the wingsdoesn't give as much lift as it should. And guess what? That canlead to a super scary situation called a stall. The planeloses control and starts hurtling downwards, totally out of control.The exact altitude where this nightmare can happen can change depending onthings like the weather and how heavy the plane is. Usually, it canoccur somewhere between 40,000 and 45,000 feet, give or take. The Dreaded Danger Zone: Now, picture this: there'sa critical point where an airplane's low-speed stall and high-speed buffetmeet. When that happens, the poor plane just can't keep itsaltitude anymore and has no choice but to descend. It's like being stuckbetween a rock and a hard place, I tell ya! For most big passenger jets, thishappens around 40,000 to 45,000 feet up in the air. But hey, keep in mind thatthe exact altitude can change depending on how heavy the plane is and what kindof weather it's facing. Hold Your Breath, Hold It Tight: Flying up really highcan put a massive strain on the airplane's structure. The pressure differencebetween the inside and outside of the plane can get so extreme that itsurpasses what the poor thing was designed to handle. And when that happens,you've got yourself a major catastrophe waiting to unfold. The plane's structure can giveway, and that's a terrifying situation that endangers everyone on board. Talkabout a nerve-wracking ride! Air Pressure Panic and Oxygen Woes: Okay, listenup! Now, planes don't melt or anything like that up in the sky, but there'sstill something to worry about when it comes to cabin pressure and oxygen. Rules and regulations in theaviation world demand that planes stay below certain altitudes to make sure thecabin stays pressurized and that there's enough oxygen for all the folks inside. We don't wantanyone turning blue or gasping for air, do we? So, altitudecontrol is a must for the well-being of everyone on board. Give 'Em Air, Give'Em Life: When planes go above their designated maximum altitude, it's bad newsfor the engine, my friend. You see, engines need a good supply of oxygen to work properly.But when they go sky-high, that supply gets all choked up, and the enginesstart struggling to do their job. They become less efficient, andthat means the plane can't maintain its altitude as it should. It's like theengine's gasping for air, and that's definitely not a good situation to be in. So there you haveit, my friend! When airplanes climb to excessive heights, they'redancing with danger. From stalls and descents to structural failures and oxygenworries, it's a wild ride up there. It's crucial for pilots andengineers to keep these risks in mind and make sure we all have a safe andsmooth journey through the sky! Q3 Whydo ceiling fans in the US have 4 or 5 blades, and fans in India have 3 blades? A3 Ramanan Rv, Travelled to and lived inUSA Upvoted by Rish Ahuj., lives in The United States of America (2010-present)Updated 6y In US and Canada, the primary requirement for the ceilingfan is to supplement the air conditioner in summer.In winter, many of these fanswith a reverse switch, can be flipped to turn the direction of the rotation sothat it will draw cold air from below so warm air from the heater(usually located along the walls close to the floor or with vents on the floor)can fill the room underneath the fans. So, the ceiling fan keeps a gentle aircirculation in the room. Also, keep in mind,the height of ceilings and hence volume of rooms are quite low inUS/Canada homes ~ 8 ft high compared to 10–12 ft in South Asia. The fans with 4 / 5 blades are slower.Also, these fans generally have a maximum of 3 speed settings. Also, the factthat they almost always double up as a lighting fixture with 1–4 bulbs underthe central hub could be one of the reasons why they need to be slow andstabilized so as not to blow the lights. The Indian fans have about 5-6 speed settings, are notdesigned to run in reverse direction and seldom double up as light fixtures.In India, the ceiling fan is used primarily as a stand alone appliance thatdoes not change the actual temperature of the room but produces a perceived cooling effect by forcedconvection of air in the room. To that effect, it just has to blow wind and operates athigher speeds than the ones in North America. So, the 3 blade fans are lighter, operate at a higher speed and aregenerally efficient. In US andCanada, the primary requirement for the ceiling fan is to supplement the airconditioner in summer. In winter, many of these fans witha reverse switch, can be flipped to turn the direction of the rotation so thatit will draw cold air from below so warm air from the heater (usually locatedalong the walls close to the floor or with vents on the floor) can fill theroom underneath the fans. So, the ceiling fan keeps a gentle air circulation inthe room. Also, keep in mind, the height of ceilings and hencevolume of rooms are quite low in US/Canada homes ~ 8 ft high compared to 10–12ft Q4 Whathappens when you eat junk food?

Reproductive issues: Junk food maycontain chemicals, such as phthalates, which can interfere with hormonal balance and potentiallylead to reproductive issues and developmental problems. 8. Skin problems: Certain junk foods,such as those high in dairy, chocolate, fat, and foods with a high glycemicindex, have been associated with acne. On the other hand, consuming fruits,vegetables, and fatty acids (found in fish and olive oil) can help promotehealthier skin. Tomaintain a healthy lifestyle, it is important to limit theconsumption of junk food. Instead, focus on a balanced dietthat includes a variety of whole foods, such as fruits, vegetables, wholegrains, lean proteins, and healthy fats.
