The speed of a car decreases uniformly from 30 m/s to 10 m/s in 4.0 seconds. the car's acceleration is-

U=30m/s
v=10m/s
t=4s
a=10-30/4
a=-5 m/second square

Answerwavelength;

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.
