For the first part we know that the wavelength is over 1.0 m so it is a radio wave.To find the period we first find the frequency as the period is the reciprical of the frequency. (T = 1/f).To find the fr...

The students stand at a distance of 200 m from each other (measured with the measuring tape). Student 1 fires the pistol, Student 2 starts the stopwatch when they see smoke from the pistol and stop it whe...

The generator effect is the induction of a potential difference (leading to a current) when a wire experiences a change in magnetic field) (2 marks)In a transformer, there are primary and secondary coils....

Velocity is displacement over time, whereas speed is distance over time. Displacement is the shortest distance from point A to point B(a straight line). In this case, the starting point(point A) is the en...
