Which quantity is a base quantity?
How can the acceleration of an object be determined?
A bucket is being lifted on a rope wound around a cylinder of diameter 200 mm. The cylinder is turned by hand using a handle 100 mm long. The weight of the bucket is 60 N.
The handle is turned through 10 complete revolutions.
How much work is done on the bucket?
A car of mass 2400 kg travels at a constant speed of 30 m/s for 10 minutes.
The brakes are then applied and the car decelerates uniformly for 0.50 minutes until the car comes to rest.
What is the breaking force?
How is the value of gravitational field strength determined?
A uniform plank is pivoted at its mid-point and a weight is added on either side in the positions shown.
A force needs to be applied at point X in order to balance the plank.
What is the magnitude of this force and its direction?
A man, of weight 800N, takes 5.0s to cycle 100m at a constant speed along a road.
The road rises vertically 1.0 m for every 50 m measured along the road.
What average power does he produce?
Work done against friction by the man can be ignored.
An insulating material contained trapped air.
Why is trapped air used in insulating materials?
Which statement about water is correct?
Springs and ropes can both be used to illustrate wave motion.
Which statement is correct?
Aray of light travelling in a glass block will change direction when it reaches the edge of the block.
What is the angle between the reflected ray and the path the ray would take in absence of a boundary?
The diagram shows a thin converging lens forming a real image of an object.
What happens to the image as the object is moved further away from the focal point F?
What happens to a sound wave as it travels through air over a long distance?
A sound wave of frequency 400 Hz travels through air with velocity 320 m/s.
The frequency of the wave in air is doubled to 800 Hz.
Which row describes the 800 Hz wave?
The diagram shows isolated positive and negative point charges. These point charges are of equal magnitude.
P, Q, R and the point charges are located on a single vertical plane.
Which statement best describes the electric field lines between two charges?
When four identical resistors are connected in parallel, their effective resistance is 0.50 Ω
What is the resistance of a single resistor?
How can the unit of electromotive force be written?
In which pair are both formulae correct?
A microwave oven uses 6.0 A of current when plugged into a 240 V mains supply.
It is used for two minutes each day and electricity costs $0.24 per kWh.
What is the cost of using it for a year (365 days)?
A ccurrent-carrying coil in a magnetic field experiences a turning effect which causes it to rotate.
The diagrams show the possible arrangements of field and current flow around the coil.
In which diagrams does the coil rotate in an anti-clockwise direction?
