Question

describe possible sources of random and systematic errors in the following measurements. lap times in the indianapolis 500 auto race. which of the following could be sources of random error? select all that apply. a. misalignment of the car detector b. frequency drift in the lap clock c. jitter in the lap clock d. electrical noise in the lap clock e. electrical noise in the car speedometer f. electrical noise in the car detector

Explanation:

Random errors are unpredictable fluctuations. Jitter in the lap - clock (C) is an irregular variation in time - keeping. Electrical noise in the lap - clock (D) can cause random variations in its operation. Electrical noise in the car detector (F) can randomly affect the detection of the car's passage, leading to random errors in lap times. Misalignment of the car detector (A) and frequency drift in the lap - clock (B) are systematic errors as they cause consistent, non - random biases. Electrical noise in the car speedometer (E) does not directly affect lap times measured by the lap - clock and detector.

Answer:

C. jitter in the lap clock
D. electrical noise in the lap clock
F. electrical noise in the car detector
