âA pendulum has a period of 1.0 s.
A stopwatch is started when the pendulum is vertical and is moving to the right, as shown.
Which diagram shows the position and the direction of the pendulum 2.5 s later?
What is the order of magnitude of the diameter of the Earth?
A pendulum has a period of 1.0 s.
A stopwatch is started when the pendulum is vertical and is moving to the right, as shown.
Which diagram shows the position and the direction of the pendulum 2.5 s later?
The diagram shows a speed-time graph.
In which region is the acceleration decreasing?
The speed-time graph shown is for a model car.
The resultant force on the car is 0.60 N.
What is the mass of the car?
What defines gravitational field strength?
A hollow rectangular metal block has the dimensions shown. The mass of the block is 819 g.
What is the density of the metal?
When a 300 N force is applied to a box weighing 600 N, the box moves 3.0 m horizontally in 20 s.
What is the average power?
A liquid is heated.
Which statement is not correct?
These terms are used in relation to waves.
1. amplitude
2. frequency
3. speed
4. wavelength
Which can be measured in metres?
The displacement-distance and displacement-time graphs are shown for a water wave in a ripple tank.
What is the speed of the water wave?
A ray of light travelling in a glass block will change direction when it reaches the edge of the block.
What is the change in the direction of the ray?
The diagram shows the main components of the electromagnetic spectrum in order of increasing frequency. Some of the components are labelled.
The component Q has frequencies below those of light.
What are electromagnetic waves in component Q used for?
A girl blows a whistle close to a cliff face.
The echo she hears has the same pitch as the original sound but it is quieter.
Which statement about the wave reflected from the cliff compared to the original sound is correct?
A man stands between two cliffs and claps his hands once.
An echo is heard which is closely followed by another.
The speed of sound is 330 m/s.
What is the time interval between the two echoes?
The diagram shows the direction of electric field lines around an isolated point charge Q.
If a charged object R is placed in the position shown, it experiences a force to the left.
What are the charges on Q and R?
The circuit diagram shows three resistors in parallel with a battery.
What is the effective resistance of these three resistors?
The diagram shows a simple d.c. circuit. The resistances of the three resistors X, Y and are equal.
Which statement is correct?
A 12 V battery is connected across a parallel arrangement of two resistors.
What is the reading on the ammeter?
A 5Ί resistor carries a current of 2 A for 10 s.
How much energy is converted into heat?
The diagram shows the pattern and direction of the magnetic field around two bar magnets.
Which diagram shows the poles of the two magnets?
