A current that runs parallel to the beach in the area where waves break is known as a longshore current. When waves hit a beach at an angle, longshore currents form. Longshore drift is the term for the transfer of silt by longshore currents.
Longshore drift is the flow of sediments along a coastline caused by waves that come in at an angle to the shore before reversing course and moving straight away. In a "sheet-like" arrangement, water in a longshore current moves up the beach before returning to the ocean. This sheet of water can carry beach sand back out to sea as it passes over and off the beach. As the longshore current sweeps down current, floating objects move up and down the beach in a zigzag manner.

Answer:
The answer is 0.008999, approximately =0.009 to 2 Demical Place
Explanation: since we have 1000 different components in the system that has just been designed.
and for it to deliver optimally we have 0.999
and for it not to deliver optimally we have 8.
so calculation wise we would have the following
0.999/1000 = 0.00099+ 0.008(8/1000)=0.008999
The governments could contribute towards this by providing an affordable -good quality welfare systems for its citizen.

Alexander's request was simple: he wished to sacrifice to Heracles in Tyre. (The Phoenician god Melqart was roughly the equivalent of the Greek Heracles.) The Tyrian's recognised this as a Macedonian ploy to occupy the city and refused, saying instead that Alexander was welcome to sacrifice to Heracles in old Tyre, which was built upon the mainland. Old Tyre held no strategic importance - it was undefended and the Tyrian navy was stationed in the harbours of new Tyre.

The Tyrian refusal to capitulate to Alexander's wishes was tantamount to a declaration of war. But, despite the youthful Alexander's growing reputation, the Tyrians had every reason to be confident. In addition to a powerful navy and mercenary army, their city lay roughly half a mile (0.8 km) offshore, and, according to the account of the historian Arrian, the walls facing the landward side towered to an impressive 150 ft (46m) in height. Whether they actually stood that high is doubtful and open to debate, but even so, the defences of Tyre were formidable and had withstood a number of mighty sieges in the past. The Tyrians began their preparations and evacuated most of the women and children to their colony at Carthage, leaving behind perhaps 40,000 people. Carthage also promised to send more ships and soldiers.
Alexander was aware of Tyre's supposed impregnability and convened a council of war, explaining to his generals the vital importance of securing all Phoenician cities before advancing on Egypt. Tyre was a stronghold for the Persian fleet and could not be left behind to threaten Alexander's rear. In a last-ditch attempt to prevent a long and exhaustive siege, he despatched heralds to Tyre demanding their surrender, but the Macedonian's were executed and their bodies hurled into the sea.
