2. A 1423-kg car is moving along a level highway with a speed of 26.4 m/s. The driver then slams her foot on the brakes where she is only moving with a speed of 10.2 m/s so she doesn't spin out over black ice that she sees ahead of her.

A: predict whether the total mechanical energy of the car is conserved or not, explain.

B: determine the magnitude of thermal energy that is produced as a result of breaking so hard.

Which of the following is not a part of the respiratory system? a. pharynx b. trachea c. pancreas d. larynx hurrim timed

The energy produced as a result of this flow of electrons from atom to atom is called
