What's the answer choices?
Answer:
Correct answer is Wave A has a greater pitch and frequency
Explanation:
To understand the given figure, we should know the definition of wavelength, frequency and pitch
Wavelength
wavelength is defined as distance between two successive wave crests or troughs.
Frequency
Frequency is defined as the number of waves which passes through a given point per second. SI unit of frequency is Hertz.
Pitch
our ear understand the frequency of a sound wave as pitch. A a lower frequency sound has a lower pitch and a higher frequency sound has a higher pitch.
In given figure Wave A has lower wavelength and higher frequency so it have higher pitch than wave B.

Id say A because the geocentric model is where the earth is at the center of the universe and all other planets, suns, stars, and moons are revolving around it
Concept: According to Ohm's Law, the flow of electric current through a conductor is directly proportional to the potential difference across it, provided physical conditions (like temperature, pressure, volume etc.) remains same.
v = ir
or, r = v / i
Here, current (i) is measured by Ammeter which should be connected in series of any electrical circuit.
voltage (v) is measured by Voltmeter which should be connected parallel to the external resistance (r).
In the given experiment, the first arrangement of the circuit will show the smallest error because the voltmeter is connected exactly parallel to the external resistance.
In the second arrangement, the voltmeter is connected across external resistance (r) and Ammeter (A) and in this case, the voltmeter will not measure the exact potential drop across the external resistance (r). So, there would be more error.
