Final answer:
The statement A wide angle "V" pattern indicated a fast-burning fire is false the correct answer is B.
Step-by-step explanation:
False. The position vs time graph of an object that is speeding up is not a straight line. When an object is speeding up, its velocity is increasing over time, which means the position vs time graph should have a curved shape. For example, if an object starts from rest and then starts moving with a constant acceleration, the position vs time graph will be a curved line. The position vs time graph of an object that is speeding up is not a straight line. the correct answer is B.
