O-Level Combined Science, Physics: Waves, Electricity and Magnetism module quiz (SEAB 5076/5077) quiz

the total energy of all the particles in an object

the mass of an object

the average kinetic energy of the particles in an object

the number of particles in an object

Convection

Evaporation

Radiation only

Conduction

Radiation travels as electromagnetic waves and needs no medium

Radiation is much faster than the others

Conduction and convection are blocked by the atmosphere

Radiation only works in a vacuum and nowhere else

along the direction the wave travels

at right angles to the direction the wave travels

only when the wave stops

in a circle around the source

speed = frequency / wavelength

speed = wavelength / frequency

speed = frequency x wavelength

speed = frequency + wavelength

is always greater than the angle of reflection

depends on the colour of the light

is always 90 degrees

equals the angle of reflection

slows down entering a more dense medium

speeds up entering a less dense medium

travels along the normal

is reflected

the energy given to each unit of charge

the rate of flow of electric charge

the opposition to the flow of charge

the total charge stored

27 ohms

12 ohms

3 ohms

0.33 ohms

is largest near the battery and smaller further away

is zero in the middle

adds up across the components

is the same at every point in the circuit

It is the same across each parallel branch

It adds up across the branches

It is largest in the longest branch

It is zero across each branch

P = V / I

P = V x I

P = I / V

P = V + I
