Rachael and Steves holiday

Rachael and Steve are going on holiday to Florida tomorrow. They have packed their bags

ready for the airport and are very excited.

The only thing Im not lookingforward to is when they use X-rays to

scan our bags at the security check.

Theres no need to worry, everything

is very safe.

25 Why is Steve correct when he says that the passengers will be safe from X-rays at the security

check?

A hospitals use X-raysB X-rays are a perfectly safe form of radiation

C the passengers are shielded from the X-rays

D X-rays do not damage the passengers healthy cells

Next day, when they reach the airport, Steve says:

I have read that we now need

to have our eyes scanned when

we travel to USA, as a securitycheck

26 Eye-scanners can be used as a security check because

27 Rachael and Steve are flying on a modern jet aircraft. Optic fibre cables are used to send

digital signals to control the aircrafts wing flaps and rudder.

Digital signals are preferred to analogue signals because

A digital signals can be sent and received more quicklyB digital signals are easier to read

C analogue signals cannot be amplified

D analogue signals are more likely to experience interference

28 The position of the aircraft is monitored by the airport control. They use radar (radio waves) to

detect how far the aircraft is from the airport. Radio waves are electromagnetic waves.

Compared with light waves, radio waves have

A a longer wavelength and lower frequency

B a shorter wavelength and lower frequency

C a longer wavelength and higher frequency

D a shorter wavelength and higher frequency

29 The radio waves travel at 300 000 000 (3 108) m/s.

The airport control measures 0.001 s (1.0 x 10- 3

s) for the radio wave to reach the aircraft and

reflect back to the airport control.

speed = distance / time

How far is the aircraft from the airport?

A 300 m

dangerous.

2 sun burn is caused by ultraviolet radiation.

37 Their teacher tells them that more than 100 planets have been observed around other stars. She

adds that for life to exist the star must have a habitable zone.

B 2 only

C both 1 and 2

D neither

38 A visiting speaker demonstrates red shift to them.

hot2 The star forms from massive clouds of gas and dust in space which gravity pulls

together

Scientists are not certain what dark

matter is made from. Alec
