A rocket is pushed forwards because its engine gases 1.are pushed backwards 2.spread outwards 3.are pushed forwards 4.surround the rocket 5.spread inwards

In outer space, the engine of a space probe is switched on for a short time. When the engine is switched off, the rocket 1.changes direction 2.moves at a steady speed 3.slows down 4.speeds up 5.follows a curved path

Which of the following is the shortest distance? The distance from the Earth to the 1.nearest star in our galaxy 2.edge of our galaxy 3.moon 4.sun 5.nearest planet

Radio waves can be detected by a 1.Geiger-Müller tube 2.photographic plate 3.scintillation counter 4.telescope 5.tuner

What is the purpose of the objective lens in a telescope? 1.To bring stars closer to the observer 2.To detect radio waves from distant stars 3.To magnify the image produced by the eyepiece 4.To produce an image that is magnified by the eyepiece 5.To split light from stars into different colours.

When a space craft enters the earth’s atmosphere, one effect of friction is to transform 1.potential energy into kinetic energy 2.kinetic energy into potential energy 3.heat into potential energy 4.potential energy into heat 5.kinetic energy into heat

Approximately how long does it take light to travel from the sun to the earth? 1.8 seconds 2.8 minutes 3.8 hours 4.8 days 5.8 years

Deep in outer space, the rocket engine of a space probe is fired for a short time and then switched off. When the engine is off the probe 1.accelerates forwards 2.Decelerates until it stops 3.Changes direction 4.Follows a curved path 5.Moves at a steady speed

A fish of mass 2 kg is hung on a Newton balance. The fish and the balance are dropped and fall freely to the sea below. What is the reading on the Newton balance while falling? 1.0 newtons 2.1 newton 3.2 newtons 4.10 newtons 5.20 newtons

Planets are objects that are in orbit around 1.moons 2.galaxies 3.meteors 4.stars 5.comets

The spectra below are for gas in a star and 3 elements, X, Y and Z. The elements present in the star are 1.X only 2.Y only 3.X and Y only 4.Y and Z only 5.X, Y and Z Star gas X Y Z

Object X of mass 1kg and object Y of mass 10kg are dropped from the same height. Both objects fall freely. Object X accelerates at 10 m/s 2. The acceleration of object Y, in m/s 2, is
