Describe the motion of all the moving parts in the diagram. Fusteigntes Reading 5 Read this description of the four-stroke cycle. Check your answers to 4. The cycle begins at fop dead centre TDC. There are four strokes ofthe piston. The crankshaft rotates. This makes the piston move down the cylinder, away from the valves.
At the same time, the cam above the intake valve rotates. This makes the valve move downwards, «which opens the intake port. As the piston moves down, fuel is sucked into the cylinder through this inlet.
As the crankshaft rotates, it makes the piston move up the chamber towards the valves, Simultaneously, the cam above the intake valve rotates and allows i to close, Both valves are now. As the piston moves up towards the valves, it compresses the fuel. Now the piston is once again at TOC. The compressed fuel i ignited by the spark plug, and there. Immediately after thi, the gases expand inthe cylinder, which pushes the piston doninwards.
As the crankshaft rotates, It pushes the piston up the cylinder. At the same time, the cam above the exhaust valve pushes the valve downwards. This opens the exhaust port, and the burnt gases are 1 pushed out. When the spark plug ignites, the gases explode. As often indicates that two actions happen simultaneously, i. When or as can sometimes be used with the same meaning when it's difficult to decide if two acti s are simultaneous or in rapid sequence, e.
At the same time, the exhaust valve opens. Immediately afterwards, there is an explosion. This makes the piston move down with great force. Simultaneously, the cam pushes the intake valve downwards. This allows the fuel to enter the cylinder. Immediately after this, it creates a vacuum in the cylinder. Soon afterwards, it puts the fuel under high pressure. This helps the gases to expand rapidly after ignition.
At the same time, the piston moves up towards it. This forces the burnt gases out of the engine. Example: 1 As the piston moves up, the exhaust valve opens, which lets the burnt gases escape. The upthrust is equal to the weight of the displaced fluid. As a liquid evaporates, it absorbs takes in heat.
Use the two principles from 1 Seems vow [ime [sou Reading 3 Read this description of a heat pump, and complete the diagram below. During cold weather, it extracts heat from the outside ar, and transfers ie into the building During hot weather, the heat pump reverses this operation, and transfers heat from inside the building to the outside.
The cols are thin pipes which are bent in a U shape many times. They can absorb and give out heat. The reftigeranc is under high [pressure as it flows fom the compressor to the condenser.
The fluid chen passes through. Here the pressute is suddenly reduced and che Duid expands. This makes it evaporate.
As the fluid passes around the evaporator cols, ic absorbs heat from the surrounding sis, making it cold. Then the fluid flows back to the compresso In cold weather, the outside coil acts as the evaporator and the inside col acs as the condenser.
The fluid in the evaporator is under low pressure, and soit evaporates. The fan pulls the outside aie over the evaporator and the fluid absorbs heat ftom it. The compressor then pumps the heated fluid into the building under high pressure o the condenser. The second fan blows air over the condenser, and the heated air is blown inco the building.

The first dummy is used for front impact crashes, and the second one is a side impact crash dummy. The dummies, which are made of steel, aluminium and rubber, contain many sensors.

What is GPS? Every 12 hours, a satelite makes an orbit, or one complete cycle in space around the Earth. The satellites transmit signals to receivers on the ground. For instance, you can now buy one Which is as small as an MP3 player. How does the system work? Each satellite sends a signal to the receiver at the speed of light. This signal tells the receiver its exact location. This gives the distance D from the receiver tothe so satelite, However, to find out your exact location that s, your longitude, latitude, and altitude , your ecelver needs signals from at least three satelites.
The receiver is able to calculate its exact location to within 6 m by comparing the three different signals. Choose the correct calculation according to the text. What do these systems calculate? Choose the most important 2. The footnotes on this web page are in the wrong order. Choose from these meanings: and, but, for example, in other words. I need to know the alttude of the planes.

Use the nouns in the box and add any necessary words. Before you touch the liquid, you should check how hot it is. Use the word s in brackets, 1 Allacroplanes carry altimeters. These devices measure air pressure. From this reading, the altimeter can calculate the height of the plane above sea level. This allows the crew to find out the location of the ships. Allidar system can work out the distance of a vehicle from the device.
It takes many readings as the vehicle approaches. From this it can calculate the speed of the vehicle. Since the system knows the speed of the sound signal, it can calculate the distance of the plane from the airport tower. Choose one that interests you. Some examples of the use of GPS include: police, fire and emergency medical services; forest fire prevention; surveying and construction; tunnel digging; bridge building; mining; company cars; delivery vans; dealing with environmental disasters such as oil spills in the sea; air-sea rescue services; agriculture; animal herding; tracking endangered species; hiking and camping; sailing.

This phone number will be yours alone. If you want to use Pinger instead of a native texting application, you must instruct all of your contacts to use your Pinger number instead of your cell phone number. This might not be an issue if you don't use your phone for voice calls or if you only text on your iPod Touch.
Pinger is available for nearly every device and operating system. You can sync multiple devices through a single Pinger account. If your phone is in another room and you receive a text, the message is retrievable through the Pinger desktop app. You can reply to the message this way as well. All the messages will also be on your phone, so you won't have to backtrack to keep the conversation going as you move from phone to laptop to tablet.
Pinger boasts a "buzzword" feature you probably don't have in your native texting app. George is a digital marketer. He likes to share his experience with informative articles. He has been in the business for more than 5 years and he has a lot of experience in digital marketing and SEO.
