Answer:
Mix
Explanation:
A battery has two electrodes, at one end it has the anode and the other end has the cathode. Electrons travel through the circuit from the anode (negative) to the cathode (positive), and this is the driving force that provides electricity to flow through circuits.
The anode needs to have a low electron affinity because it needs to readily release electrons, and the cathode needs to have a high electron affinity because it needs to readily accept electrons.
the new momentum would be 40000 units as momentum = mass × velocity
The general formula for the frequency of the nth-harmonic of the column of air in the tube is given by

where f1 is the fundamental frequency.
In our problem, we have two harmonics, one of order n and the other one of order (n+1) (because it is the next higher harmonic), so their frequencies are


so their difference is

So, the difference between the frequencies of the two harmonics is just the fundamental frequency of the column of air in the tube, which is:
Answer:
please specify you question well
Earths surface gravity: 9.7
Venus surface gravity: 8.8
Mercury's surface gravity: 3.7
Your answer would be D: Earth, Venus, Mercury
