Acar is uniformly accelerated at the rate of 2 m/sec2 for 12 seconds. if the original speed of the car is 36 m/sec what is the final speed

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?

How many electrons does each element require in its valence shell to become stable?

First to answer will be the brainliest i need the answer asap
