A1 Location Suez Canal Start SinaiPeninsula End Suez Operation-Constructed TarmacConstruction Opened 1981,Reopened 1992 Technical Length 1.63 km (1.01 mi) No. of lanes 2 Location of Ahmed Hamdi Tunnel that goes under theSuez canal The Ahmed Hamdi Tunnel is a 1.63-kilometre-long (1.01mi) car tunnel under the Suez Canal at Shallufa. The tunnel is named after Ahmed Hamdi, an Egyptianengineer and general killed in action during the Yom Kippur War. It has two lanesof traffic, one in each direction, and it connects the Asian Sinai Peninsula tothe town of Suez on the African mainland. Construction It was originally constructed as a shield tunnel byTarmac Construction in November 1981. In 1992, the Japanese government grantedaid to a project aimed at rehabilitating the tunnel which had developed leaks. It is 1.63 kilometres (1.01 mi)long and has an outside diameter of 11.6 metres (38 ft).[3] The tunnelreaches a maximum depth of 51metres (167 ft) below ground level.[4][5] Significantdevelopments in the region The tunnel was part of a major drive to develop theareas surrounding the Suez Canal, including other projects such as the Suez Canal overhead line crossing(completed in 1998), the El Ferdan Railway Bridge, and the Suez CanalBridge (completed in 2001).

Q2 Isdrinking water right before sleeping good or bad? A2 MiaDelacroix,Senior Nutritionist at Clinics (2013–present)Sep 30 Drinking waterright before sleeping can have both advantages and disadvantages, depending on individualfactors and preferences. Here's a detailed explanation, along with scientificinsights: Drinking WaterBefore Sleeping: Advantages: Hydration: Stayingadequately hydrated is important for overall health. Drinking water before bed can help ensurethat you are properly hydrated, especially if you haven't consumed enoughfluids during the day.Scientific Study: Proper hydration is essential forvarious bodily functions, including circulation, temperature regulation, andwaste removal. Reduced MorningDehydration: Drinking water before bedtime may reduce the risk of waking up with a dry mouth orfeeling excessively thirsty in the morning. Scientific Study: Research in the "Journal ofClinical Sleep Medicine" (2007) discussed the effects of dehydration onsleep quality and morning discomfort. Disadvantages: Night timeWaking: Consuming a large amount of water shortly before bed may lead to night time waking touse the bathroom, disrupting your sleep pattern. Scientific Study: Research inthe "Journal of Urology" (2012) explored the impact of nighttimeurinary frequency on sleep quality. Heartburn: Forsome individuals, drinking water before lying down can increase the risk of acid reflux orheartburn, particularly if the stomach is still digesting a late dinner. ScientificStudy: A study published in "Gut" (2015) discussed the relationshipbetween nighttime reflux and fluid consumption. Best Practices: Moderation: Ifyou choose to drink water before bed, do so in moderation. Sip a small amount to quenchthirst without overloading your bladder. Timing: Aim todrink water at least an hour before bedtime to reduce the likelihood of night time waking. ConsiderIndividual Factors: Your personal preferences, habits, and any existing medical conditionscan influence whether drinking water before bed is beneficial or not. Considerwhat works best for you. In conclusion, whether drinking water before sleepingis good or bad depends on various factors, including your hydration status, sleep habits, andtolerance to nighttime waking. It'simportant to strike a balance between staying hydrated and avoiding disruptionsto your sleep. Q3 Is thereanother force other than gravity that is keeping our solar system together,including Earth and everything else in it? A3 RudiWidiyanto, Lives in Jakarta (2015–present)8h Yes, there is another force other than gravity that is keepingour solar system together, including Earth and everything else in it. That force is called centripetal force 1. Centripetalforce is the force that makes an object move in a circular path. It is always directed towards the center of thecircle. In our solar system, the centripetal force that keeps theplanets in orbit around the Sun is provided by the Sun’s gravity 2The Sun’s gravityis very strong because the Sun is very massive and has a lot of matter. The more matteran object has, the stronger its gravity is. The Sun’s gravity pulls the planetstowards it, but the planets also have their own speed and direction, calledvelocity. The planets’ velocity makes them want to move in a straight line,away from the Sun. This is called inertia. Inertia is the tendency of an objectto resist any change in its motion. The balance between the Sun’s gravity and theplanets’ inertia creates a curved path, or an orbit, around the Sun1 The shape of theorbit is not a perfect circle, but an ellipse, which is like a stretched-outcircle. The orbits of the planets are slightly elliptical, meaning that they arecloser to the Sun at some points and farther away at others. The orbitsof some objects, like comets, are very elliptical, meaning that they have avery long and narrow shape. The orbits of the planets and other objects in oursolar system are also affected by the gravity of other planets and objects. Sometimes, these gravitational interactions can causesmall changes in the orbits, called perturbations. For example, the orbit of Mercury, the closestplanet to the Sun, is slightly perturbed by the gravity of Venus, the secondclosest planet. These perturbations are very small and do notaffect the stability of the solar system, but they can be measured by preciseobservations1 I hope this answer helps you understand the forcesthat keep our solar system together.

A4 StevenHaddock, Lives in Toronto, ON (1959–present)16h Usually in nearbymountains where snow falls heavily in the winter and melts throughout the year. The literal cradle of civilization, Mesopotamia(literally the land between the rivers) has the Tigris and Euphrates, whichstart in different places but meet near the coast. They flow from mountains in modern Turkeysouthwards to the Persian Gulf through modern Iraq. Most of theway they flow through very dry areas that get very little rain (Baghdadaverages 6 inches a year, which is just above “desert”) but so much snow fallsin the mountains that the river flows pretty much uninterrupted all year. Since the Dead Sea is in the picture….. The source ofthe Jordan River, one of the main water sources for both Israel and Jordan,starts way up in the mountains that largely form the border between Lebanon andSyria. See, snow. That snow melts and feed the river, which eventually winds up in abasin unconnected from the ocean called the Dead Sea which gets between 2–3inches of rain a year, but is still full of water (although it’s gettingprogressively saltier). However, the northern parts of Galilee, whichalso drains into this watershed, do get about 40 inches of rain a year,although the southern parts might only get a single inch. Q5 Can webuild a 300 km long Tunnel? A5 GopalkrishnaVishwanath, Retired Structural Engineer & language and internet/socialmedia enthusiast.6h It would bechallenging. Itwould be horribly expensive. It would take decades to build. It would need areason to be built. There should be two places that need such a tunnelconnection. But It is not impossible. Thelongest tunnel built so far is this one. This is the Gotthard Base Tunnel in Switzerland. Itis 57.1 kilometers(35.5 miles) long. It was opened in2016. The tunnel ispart of the AlpTransit project, which is a major infrastructure project toimprove railtransport across the Alps. The GotthardBase Tunnel is a key part of this project, as it provides a direct routebetween northernand southern Switzerland, bypassing the winding mountain roads that werepreviously used. So if this waspossible in 17 years, all it needs is some more years, some more money and areason for spending it. The tunnel shouldbe economically viable. Finding a reason and a place to build such a tunnel is morechallenging than building it. My note-Mr G Viswanath was a member of Thatha Pattiyahoo groups.
