the distance from the original position in a particular direction
What is displacement
100
measure of the average kinetic energy of the molecules in a substance
What is temperature
100
is a measure of how ‘in step’ different waves are
What is phase difference
100
is defined as the ratio between p.d. and current
What is resistance?
200
rate of change of velocity in a particular direction
What is acceleration
200
is the energy required to raise the temperature of an object by 1 K
What is thermal capacity
200
is represented by the symbol ω
What is angular frequency
200
the difference in electrical energy per unit test charge between two points.
What is potential difference (voltage)?
200
These lines from "+" to "-"
What are electric field lines
300
the value at one particular instant of time
What is instantaneous
300
the amount of energy per unit mass absorbed or released during a change of phase.
What is specific latent heat
300
are formed when two waves of identical amplitude and frequency which are travelling in opposite directions meet. The result is a wave pattern whose shape does not travel through space.
What is a standing wave
300
1/R = 1/R1+1/R2+1/R3+....
What is the equation for the equivalent resistance for a parallel circuit?
300
the amount passing through one turn of a coil is φ
What is magnetic flux?
400
ratio of useful power out to total power in
What is efficiency
400
PV = nRT
What is equation of state for ideal gas
400
these type of waves involve oscillations that are in the same direction as the direction of energy transfer.
What are longitudinal waves
400
the force per unit charge on a test point charge placed at that location.
What is the the electric field at a certain location
400
the value of an alternating current (or voltage) is the value of the direct current (or voltage) that dissipates power in a resistor at the same rate.
What is the root mean square (rms) value?
500
is the product of the resultant force acting on the object and the time for which this force acts
What is impulse
500
a change in state that takes place at constant volume.
