The wavelength most likely observed by the astronaut is ______. A 600 nm B 620 nm C 660 nm D 680 nm (2) 1.4 What physical quantity is associated with kg.m.s-1? A Impulse B Power C Work performed D Energy (2) 1.5 Which ONE of the following forces always acts straight downwards even if the angle of the surface on which an object is standing changes? A Normal force B Frictional force C Gravitational force D Tension (2) 1.6 Which ONE of the following equations represents the principle of conservation of mechanical energy? A ΔEk = ΔEp B ΔEp = -ΔEk C ΔEk + ΔEp – Wnc = 0 D ΔEk – ΔEp = Wnc (2) 1.7 Two stones, X (mass 1 kg) and Y (mass 2 kg), are dropped within a vacuum at the same time. The initial velocity of each stone is zero. Which one of the following statements is the best description for the movement of both stones? A X will reach the ground first. B Y will reach the ground first. C X and Y will reach the ground simultaneously at the same velocity. D X and Y will reach the ground simultaneously, but Y will have the greater velocity. (2) 1.8 Diagram 1 gives the expected absorption spectrum of an object in space. Diagrams 2 and 3 give the absorption spectra received by the object of star 1 and star 2 respectively. The numbers above and below the spectra indicate the wavelength in nm. The correct statement regarding the Doppler displacement and movement of the stars relative to the object is: Star 1 Star 2 A Red shifts and moves away Red shifts and moves closer B Blue shifts and moves away Red shifts and moves away C Red shifts and moves away Blue shifts and moves closer D Blue shifts and moves closer Red shifts and moves away (2) 1.9 A ball is thrown vertically downwards from a certain height above the floor. The ball bounces on the floor several times. The following velocity-time graph represents the motion since the ball was thrown. Ignore the effects of friction. Which point (P, Q, R or S) on the graph indicates the maximum height after the first bounce? A P B Q C R D S (2) 1.10 The diagram illustrates a truck towing a trailer. The force exerted by the trailer on the truck is ______. A less than the force exerted by the truck on the trailer and is to the left. B equal to the force exerted by the truck on the trailer and is to the right. C less than the force exerted by the truck on the trailer and is to the right D equal to the force exerted by the truck on the trailer and is to the left.
