An electron is moving with uniform circular motion around a circle of radius 6 cm. Its initial rotational kinetic energy is 24 J. If its (translational) speed doubled and it kept moving around the same circle, then how much rotational kinetic energy would it have?

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct?
