Edexcel A-Level Physics Thermodynamics, space and oscillations overview quiz quiz

Celsius

Fahrenheit

Any scale works

Kelvin

Change the state of 1 kg at constant temperature

Raise the temperature of 1 kg of the substance by exactly 1 K

Raise the temperature by 1 degree Celsius

Melt the entire sample completely from solid to liquid

$kT$

$\frac{3}{2}kT$

$\frac{1}{2}kT$

$3kT$

It has no acceleration because its speed stays perfectly constant

It accelerates outwards, directed away from the centre of the circular path

It accelerates towards the centre because its velocity direction changes

Its speed changes continuously as it travels around the circle

$F = \frac{mr}{v^2}$

$F = mvr$

$F = \frac{v^2}{mr}$

$F = \frac{mv^2}{r}$

Acceleration is proportional to displacement and directed towards equilibrium

Acceleration stays constant in both size and direction throughout the whole cycle

Velocity is constant in both magnitude and direction during the motion

Displacement increases linearly with time at a steady, uniform rate

At the extremes of displacement

At the equilibrium position

Everywhere the same

Where acceleration is greatest

Any frequency

Twice its natural frequency

Its natural frequency

Zero frequency

Its distance from the Earth

Its physical radius

Its measured redshift

Its surface temperature

An expanding universe

A static universe

A contracting universe

A universe with no galaxies
