Heat always flows from higher temperature to lower temperature. So option A. heat will flow from the air into the coolant is the correct answer.
Answer:
Acceleration is the rate of change of velocity. If an object is changing its velocity, its speed, or changing its direction, then it is said to be accelerating.
Explanation:
when you change directions or speed up you are accelerating (or decelerating) and when you change directions or speed its called velocity.
Answer:
175 m
Explanation:
The average velocity for constant acceleration is the average of the beginning and ending velocities. That is (0+39)/2=19.5 m/s. If the bicyclist rides for 9 seconds, the distance traveled is ...
(9 s)(19.5 m/s) = 175.5 m
She would travel 175.5 meters in that time.
