[超簡化篇] Cut去所有graph, 圖題目。
原版程度: 英國中5(精英組)/ 香港中5~7(估計) <--不過呢份野事實係比我簡化左好多! XDD
form1仔絕對0岩玩XD
[改編]
時間: 2 hours(?)
備註: equation=formula.
請自己做完之後﹐自己去"Answers"度自己改卷XDD

The follwing represents the electromagnetic spectrum.
|Gamma Rays| X-rays | Ultraviolet| Visible light| Infra red| Microwaves| Radio waves|
Name the type of electromagnetic radiation that is used to:
1) sterilise surgical instruments. [1mark]
2) to send a signal to a TV from remote control.[1mark]
3) Valuable items can be security marked using special ink. The ink can only be seen in ultraviolet radiation.
Explain what happens to make the ink visible. [2]
4. Explain why skin cells need to be pretected from Ultraviolet radiation.[2]
The following information is from an oven that combines a microwave and a grill.
Voltage-230V
Microwave power-0.65kW
Grill power--1.15kW
5. Name 2 types of electromagnetic radiation that the oven can use to cook.[1]
6. Both are switched on at full power for half an hour. Calculate energy transfered, in kWh, by the oven. [2]
7. Which 2 are the same element? [1]
a) 7proton 7neutron 7 electron
b) 6 6 6
c) 6 8 6
8. Give your reasons to your answer[1]
9. A Space shuttle takes 9 mins to reach its orbital velocity of 8100m/s
Write down the equation that links acceleration, change in velocity and time taken. [1]
10. Calculate in m/s, the average acceleration, of the space shuttle during the first 9 minutes of its flight. Show clearly how you work out your answer.
[2]
11. How is the velocity of an object diffrerent from the speed of an object? [1]
12. The space shuttle can stay in orbit around the earth for several weeks. Esplain why it stays in orbit and does not fall. [2]
13. As the shuttle returns to earth, friction causes its outside temperature to go as high as 1200C. Why is the underneath of the shuttle covered with black tiles?[1]
14. Jill weighs 700N and Greg weighs 500N. They are carried by a charlift to 200m high. Write down the equation that links distance moved, force applied and work done. [1]
15. Calculate work done to lift Greg and Jill. [3]
16. The chair takes 5mins to move from the bottom to the top of the ski slope. Use the following equation to calculate the power required to lift Greg and Jill to the top of the ski slope. [2]
power=work done/ time taken
[
17. What word can be used for "the flow of electrons"? [1]
18. How is a thermistor affected by an increase in temperature? [2]
19. Write down the equation that links acceleration, force and mass. [1]
20. Write down the equation that links current, potential difference and power. [1]
21. Use the theory of plate techtonics to explain sea floor spreading. [2]
22. What evidence is there to support the idea of sea-floor spreading?[1]
23. Write down the equation that links frequency, wavelength and wave speed. [1]
24. A lens is used as a magnifying glass. What type of lens is it? [1]
25. Two points are marked as F. In ray diagrams. What are these points? [1]
26. What is the name of the straight line which goes through F, through the centre of the lens, and through F on the other side? [1]
27. Write down the equation, in words, which you need to use to calculate momentum. [1]
28. Write down the equation which connects change in momentum, force and time. [1]
29. Which part of an atom emits a beta particle? [1]
30. How does the composition of an atom change when it emits a beta particle? [1]
