Scientists now gathered information and facts before creating a theory.
Answer:
I may be a little late, but it's A i got it right on the exam
Explanation:
The gravitational pull of Earth is stronger in satellite A
The fundamental frequency of the tube is 0.240 m long, by taking air temperature to be
C is 367.42 Hz.
A standing wave is basically a superposition of two waves propagating opposite to each other having equal amplitude. This is the propagation in a tube.
The fundamental frequency in the tube is given by
![f=\frac{v_T}{4L}](https://tex.z-dn.net/?f=f%3D%5Cfrac%7Bv_T%7D%7B4L%7D)
where, ![v_T=v\sqrt{\frac{T}{273} }](https://tex.z-dn.net/?f=v_T%3Dv%5Csqrt%7B%5Cfrac%7BT%7D%7B273%7D%20%7D)
Since, T=37+273 K = 310 K
v = 331 m/s
![\therefore v_T=331\sqrt{\frac{310}{273} } = 352.72 \ m/s](https://tex.z-dn.net/?f=%5Ctherefore%20v_T%3D331%5Csqrt%7B%5Cfrac%7B310%7D%7B273%7D%20%7D%20%3D%20352.72%20%5C%20m%2Fs)
Using this, we get:
![f=\frac{352.72}{4(0.240)} \\f=367.42 \ Hz](https://tex.z-dn.net/?f=f%3D%5Cfrac%7B352.72%7D%7B4%280.240%29%7D%20%5C%5Cf%3D367.42%20%5C%20Hz)
Hence, the fundamental frequency is 367.42 Hz.

Answer:
+ 14
Explanation:
18 protons make a positive 18 charge (+18)
4 electrons make a negative 4 charge (-4)
both combined give + 18 - 4 = + 14
The four neutrons don't carry net charge, so the addition of the electrons doesn' affect the net charge found above which still gives + 14.
