It is a fact that the number of beats on a string which is being tuned equals the difference of the frequencies of the component waves. In this case the component frequencies are the correct frequency and the measured frequency. The beat frequency is equal to 1/4=0.25 Hz. Therefore this is the difference between the correct frequency and the measured frequency. The correct option is D).

Hey, could someone help me work out this physics-electricity problem? And would you write out your steps please? that would be a big help. thanks! Two charges of +4.0 nC and -1.0 nC are fixed to a baseline at a separation of 1.0 m. Where on the baseline should a third charge of +2.0 nC be placed if it is to experience zero net electric force?

Question:
A chemist measures the potential of an electrochemical cell
vs. the saturated calomel electrode to be +0.5V. Then, the chemist
switches the reference electrode to the silver-silver chloride
electrode.
What should the voltage read?
Use the following diagram to assist your thought
process:
Previously we discussed a calomel reference electrode. A second type of reference electrode is also very common in lab - this one is called the...
