Notes:


3 - Ans: A.
An aeroplane can fly at a velocity X when moving through still air. When flying in wind the aeroplane’s velocity relative to the ground is Y.


4 - Ans: A.
A voltmeter gives readings that are larger than the true values and has a systematic error that varies with voltage.


6 - Ans: B.
A cyclist pedals along a raised horizontal track. At the end of the track, he travels horizontally into the air and onto a track that is vertically 2.0 m lower.


7 - Ans: B.
An astronaut on the Moon, where there is no air resistance, throws a ball. The ball’s initial velocity has a vertical component of 8.00 m s-1 and a horizontal component of 4.00 m s-1, as shown.


11 - Ans: A.
A car has mass m. A person needs to push the car with force F in order to give the car  acceleration a.


15 - Ans: D. See solution 88 at
Four beams of the same length each have three forces acting on them.


16 - Ans: B.
An air-conditioning unit is supported by a rigid beam PQ, as shown.



19 - Ans: A.
A truck of mass 500 kg moves from rest at the top of a section of track 400 m long and 30 m high, as shown. The frictional force acting on the truck is 250 N throughout its journey.



25 - Ans: D.
The graph shows the variation with time of the displacement X of a gas molecule as a continuous sound wave passes through a gas.


26 - Ans: C.
The warning signal on an ambulance has a frequency of 600 Hz. The speed of sound is 330 m s-1.


31 - Ans: B.
The diagram shows an electric field pattern caused by two positive and two negative point charges of equal magnitude placed at the four corners of a square.


32 - Ans: A.
Two large horizontal metal plates are separated by 4 mm. The lower plate is at a potential of –80 V.



36 - Ans: D.
In the circuit shown, the reading on the ammeter is zero. The four resistors have different resistances R1, R2, R3 and R4.
