A stone is dropped from a tall tower and falls a distance of 50 m to the ground. The stone has a mass of 3.0 kg. At which speed does the stone hit the ground?

A coal-fired power station generates electricity. Coal is burned and the energy released is used to boil water. The steam from the water makes the generator move and this produces electricity. Which row gives the name of the energy store in the coal and the energy store of the moving generator? [Table_1]

Gas of volume 200 cm^3 is trapped inside a container by a piston. The piston is pushed to the right and the volume of the gas decreases to 100 cm^3. The temperature of the gas remains constant. Which row states the effect that this has on the kinetic energy of the gas particles and the force per unit area exerted by the particles colliding with the inside walls of the container?

Which graph shows the relationship between the pressure and volume of a fixed mass of gas at constant temperature?

During evaporation of a liquid, the most energetic particles escape. The temperature of the remaining liquid changes.
Which row identifies where these particles escape from and describes the temperature change?

A magnetic field is represented in the diagram by magnetic field lines. At which point is the magnetic field strongest?

A student determines the resistance of resistor R. She uses a circuit including a voltmeter and an ammeter. Which circuit does she use?

A diode and a resistor are connected across a variable d.c. supply. Terminal X is initially positive and at a maximum value. The potential difference (p.d.) across XY is adjusted so that it changes, as shown by the graph.
Which graph shows how the current in the circuit (from X to Y) varies during the same time interval?

When a conductor in a complete circuit cuts across a magnetic field, a current is induced in the conductor. Which statement about the induced current is correct?

The diagram shows a solenoid carrying an electric current.
Which row compares the strength of the magnetic field due to the solenoid at points Y and Z with the strength of the magnetic field at point X? [Table_1]

A conducting wire is placed between the poles of a magnet. When an electric current in the wire is in the direction shown, then the force on the wire acts out of the page.
Three statements of different conditions and how the wire is affected are given.
1. When the current is towards the top of the page and the direction of the magnetic field is unchanged, the force produced acts into the page.
2. When the current is towards the bottom of the page and the magnetic field is reversed, the force produced acts into the page.
3. When the current in the wire is alternating, the wire vibrates into and out of the page.
Which statements are correct?

Which types of electric current are in the primary coil and the secondary coil of a step-up transformer? [Table_1]

A scientist fires alpha-particles at a very thin sheet of gold and detects the particles that pass through.
Which statement about the results of the scattering experiment is correct?

The notation represents the nucleus of a gold atom. $$ ^{197}_{79}\text{Au} $$ The relative charge on a proton is +1. What is the relative charge on the gold nucleus?

An isotope of hydrogen has the nuclide notation $^2_1H$.
