A particle moves along a straight line such that its position is defined by s = (t^3- 3t^2 2) m. Determine the average velocity, the average speed, and the acceleration of the particle when t = 4 s.

The modern-day generator works on the principle of electromagnetic induction discovered by michael faraday in 1831-32. faraday discovered that the above flow of electric charges could be induced by moving an electrical conductor, such as a wire that contains electric charges, in a magnetic field.

The anwser is: wave a has a greater pitch and frequency.
