2 - Ans: D.
A crane has an arm to which is attached a frictionless pulley. A cable passes over the pulley and supports a load of 10 kN as shown.



7 - Ans: A.
A car is travelling at constant velocity. Its brakes are then applied, causing uniform deceleration.

9 - Ans: B.

Which statement defines force?  A When a force acts on a body that is free to move, the force is the product of the mass of the body and its acceleration.

10 - Ans: B.
A particle of mass m, travelling with speed u, collides with a stationary particle of mass M.


15 - Ans: C.
The force diagram shows an aircraft accelerating. At the instant shown, the velocity of the aircraft is 40 m s-1.


16 - Ans: C.

A man is running in a straight line. What is an approximate value of his kinetic energy?

19 - Ans: B.
The Young modulus of steel is twice that of copper. A 50 cm length of copper wire of diameter 2.0 mm is joined to a 50 cm length of steel wire of diameter 1.0 mm, making a combination wire of length 1.0 m, as shown.

25 - Ans: C. See solution 1120 at

A musical instrument called a bugle is a long tube with a mouthpiece at one end. The other end is open and flared, as shown.

28 - Ans: A.
The electric field strength at a certain distance from an isolated alpha particle is 3.0 × 107 N C-1.

34 - Ans: D.

Three cells with e.m.f.s V1, V2 and V3, have negligible internal resistance. These cells are connected to three resistors with resistances R1, R2 and R3, as shown.

37 - Ans: A.
The battery of a car has an internal resistance of 0.10 Ω and an electromotive force of 12 V.
