Electronegativity, symbol χ, measures the tendency of an atom to attract a shared pair of electrons (or electron density). An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus.
A. 1 dimensional coordinate system
All waves have an amplitude, wavelength, and frequency.
Amplitude is how far away the wave moves from its resting place. When drawn on a graph, the amplitude is the distance between the upper (crests) and lower (troughs) points and their center on the wave.
Wavelength is the distance two crests or troughs are away from each other.
Frequency is the number of waves produced in a set amount of time. The unit used to measure frequency is Hertz (Hz).
With sound waves, the frequency determines the pitch. The higher the frequency, the higher the pitch, and vice versa. So, a bass drum, which has a low pitch, would have a lower frequency than a mosquito's whine, which is very high pitched.
Light waves are actually electromagnetic waves. Their frequency determines what kind of wave they are, whether it's gamma rays, ultraviolet, x-rays, or something else.

b) The drag force is:

Explanation:
Not enough information. It really depends on the technical details of the car ( the data provided is offering just the human factor of the reaction, not the time for getting the impulse through when using the breaks
