<span>Delta(f) =f0 * v_rel/c , where v_rel is the relative velocity between source and observer.
The source is moving at a speed v but the sound bounced off the wall and the receiver is moving toward it too.
So,
Delta(f) = f0 (2 V) / c
Hence
V = c Delta(f) /(2 f0)= 344 m/s * (7.00Hz/(2*245Hz)) =4.91 m/s</span>
Answer:
B. It can be answered using measurements.
Explanation:
Scientific inquiry can be defined as the various ways, techniques and approach used by scientists to study the world and provide a detailed description (information) based on the empirical evidence derived from the investigation.
Measurements can be defined as a technique which typically involves the process of identifying and determining the dimensions, quality and quantity of a physical object.
Hence, the statement which best describes a characteristic of a question that can be answered through scientific inquiry is that, it can be answered using measurements. Using scientific inquiry to answer questions entails using measurements to propose specific and evidential explanations, as well as back up theories associated with the question.
Horizontal component = 75 · cosine(65°) = 31.7 N
Vertical component = 75 · sine(65°) = 68.0 N
