If the current is 8.6 A. find the voltage drop across the arrangement and the current in each resistor (1 decimal place). 2. One resistor group consists of 40, 60 and 80 connected in parallel and a second group consists of 30 and 60 in parallel. The 2 groups are connected in series across a 24 V supply. Calculate (a) the circuit current, (b) the P.D. across each group and (c) the current in each resistor (all 2 decimal places). 3. Two resistors of 60 ks2 and 40 k2 value are connected in series across a 240 V supply and a voltmeter having a resistance value of 40 k is connected across the 40 ko resistor. What is the reading on the voltmeter (2 significant figures)? 4. Two groups of resistors A and B are connected in series. Group A consists of 4 resistors of values 20, 40, 60 and 80 connected in parallel and group B consists of 2 resistors of values 100 and 150 in parallel.

7 An important issue for a retailer is to decide when to reorder stock from a supplier. A common policy used to make the decision is of a type called s, S: The retailer orders at the end of a period if the on-hand stock is less than s, and orders enough to bring the stock up to S. The appropriate values of s and S depend on different cost parameters, such as inventory holding costs and the profit per item sold, as well as the distribution of the demand during a period. Consequently, it is important for the retailer to collect data relating to the parameters of the demand distribution. Suppose that the following data give the numbers of a certain type of item sold in each of 30 weeks. 14, 8, 12, 9, 5, 22, 15, 12, 16, 7, 10, 9, 15, 15, 12, 9, 11, 16, 8, 7, 15, 13, 9, 5, 18, 14, 10, 13, 7, 11

OFFERING ROBES m or "PHA PA means clothes forest Money tree During the feast called "PHA PA", money is given to restore the temple buildings but also to get funds to build new buildings. Such tree is called money tree The "PHA PA ceremony can happen at any time in the year. On the contrary "THOT KATHIN" ceremony only happens once a year and just after the end of the rain retreat. The name "PHA PA" can be translated to "clothes forest. A long time ago, monks only wear clothes made from old rags of dead people. So faithful people sometimes placed clothes on the tree branches in the forest. That is the origin of the "PHA PA ceremony. Directions: Answer these questions about Thot Khathin and Thot Pha Pa. 1. What is Kathin? 2. How long are the robes of Buddhist monks cut ? 3. Who would make Kathin robes in the olden times ? 4. When is a period of four weeks? 5.

Q Volcanoes Read the passage below and answer the questions on the next page. 4G 54 Volcanoes are geological formations that are created due to the movement of magma and gas from the Earth's mantle and core to its surface. The Earth's crust is made up of several large tectonic plates that are in constant motion, and when these plates collide, magma is forced to the surface, resulting in volcanic eruptions. Games4esl Volcanoes can be found all over the world and are often located in areas where tectonic plates converge, such as the Pacific Ring of Fire. Volcanoes can be classified into three main types: shield volcanoes, stratovolcanoes, and cinder cone volcanoes. Shield volcanoes are formed by repeated eruptions of fluid lava flows, which are thin and runny due to low viscosity. As the lava spreads out, it forms a wide, gently sloping mountain. Stratovolcanoes are steep, cone-shaped mountains that are formed by layers of ash, lava, and other volcanic debris. They are typically the result of explosive eruptions. Cinder cone volcanoes are small, steep-sided cones that are formed from a single vent and have a circular crater at the top. They are usually created by explosive eruptions that produce a lot of ash and cinders. |||| Volcanic eruptions can be very destructive and can cause damage to both the natural environment and human infrastructure. They can cause ash clouds that can travel for miles and disrupt air travel, as well as pyroclastic flows, which are fast-moving clouds of hot gas, ash, and rock that can be deadly. In addition to causing destruction, volcanic eruptions can also be beneficial, as they can create new land, enrich soil with minerals and nutrients, and provide sources of geothermal energy. 3 Scientists study volcanoes in order to better understand their behavior and predict when eruptions might occur. They use instruments such as seismometers, gas sensors, and satellite imagery to monitor the activity of volcanoes and track changes in their behavior. This information can be used to create early warning systems that can help protect people and communities from the effects of volcanic eruptions. www.Games4esl.com

I have at the professional level for many years now, and I've even won a few tournaments su Target archery is a very popular sport, and it is particularly popular in my country. You could almost call it a national pastime for Koreans. There are even archery cafés in Korea! This might be why South Korea is known for producing some of the most talented archers in recent years. In fact, South Korean archers grabbed gold medals in all four categories of archery at the 2016 Rio Olympic Games. The rules of target archery are simple. Archers shoot at a stationary target. Indoor competitions take place at 18m. Outdoor ranges can be from 25m to 90m. Each match is divided by ends which are counted as either three or six arrows. Archers shoot their arrows at a target with ten rings drawn on it. Each ring's value gets higher as it nears the center. After firing all shots, archers add up their scores and the archer with the most points at the end of the competition wins. GEOCACHING Hello, I'm Andrew and I have been an active geocacher for more than ten years. Geocaching is an activity for people who love exploration and adventure. It's essentially a giant game that involves using Global Positioning System (GPS) receivers to search for hidden treasures called geocaches. There are all kinds of geocaches. Some are very simple to find and others require the participant to solve puzzles to learn the cache's location. What waits inside each cache is a mystery. Geocaches can contain all sorts of different treasures, such as CDs, books, USBS, and even money. One common item in almost every geocache is a logbook. The logbook is a record of all the participants who have found the cache and contributed to it. 1 If you're interested in seeing what treasures lie out there, you can try this activity out yourself. Look online for nearby geocaches. There may be some nearby. Find one and then set off on your first geocaching adventure. All you need is a smartphone and a little bit of time to join in the fun. NOTE Go online and try to locate a geocache near you. Who do you think placed it there? Comprehension 5 Circle true or false. true 1. South Korean archers performed poorly at the Rio Olympics. 2.
