<h2>
<u>RANCIDITY</u><u>:</u></h2>
=> Rancidity is a condition in which the substance with oil and fats get oxidized when they are exposed to air. A substance is said to be rancid when there is a change in smell, taste, and colour. An example of rancidity is when a chips pack is exposed to atmospheric air which results in a change in taste and odor.

The gravitational force on two objects can be determined by the following equation:
![F=G\frac{m_{1}m_{2}}{r^2}](https://tex.z-dn.net/?f=F%3DG%5Cfrac%7Bm_%7B1%7Dm_%7B2%7D%7D%7Br%5E2%7D)
Where G is the gravitational constant m1 is mass 1, m2 is the second mass nad r^2 is distance between these objects. Therefore, let m1 = mass of Sun 1.99x10^30 kg, m2= mass of Jupiter 1.90x10^27 kg, r is the average distance between the Sun and Jupiter 7.78x10^11 m. By plugging these values in we have:
![F=6.67x10^{-11}\frac{(1.99x10^{30})(1.90x10^{27})}{(7.78x10^{11})^2}](https://tex.z-dn.net/?f=F%3D6.67x10%5E%7B-11%7D%5Cfrac%7B%281.99x10%5E%7B30%7D%29%281.90x10%5E%7B27%7D%29%7D%7B%287.78x10%5E%7B11%7D%29%5E2%7D)
![F=4.1665x10^{23}](https://tex.z-dn.net/?f=F%3D4.1665x10%5E%7B23%7D)
F=4.17x10^23 N
Given parameters:
Frequency of the wave = 1520kHz = 1520 x 10³Hz
Unknown:
Wavelength of the radio photon = ?
Energy of the wave = ?
Solution:
The wavelength of any electromagnetic wave can found using the expression below;
C = f x ∧
Where C is the velocity of light = 3 x 10⁸m/s
f is the frequency of the wave
∧ is the wavelength
Since the unknown is ∧, input the known parameters and solve for it;
3 x 10⁸ = 1520 x 10³ x ∧
Wavelength =
Wavelength = ![\frac{3 x 10^{8} }{1.52 x 10^{6} }](https://tex.z-dn.net/?f=%5Cfrac%7B3%20x%2010%5E%7B8%7D%20%7D%7B1.52%20x%2010%5E%7B6%7D%20%7D)
Wavelength = 1.97 x 10²m
ii. Energy of the wave;
Energy of a wave = hf
where h is the planck's constant = 6.63 x 10⁻³⁴ J Hz⁻¹
f is the frequency of the wave
Input the parameters and solve;
Energy of the wave = 6.63 x 10⁻³⁴ x 1.52 x 10⁶
= 10.1 x 10⁻²⁸J
The energy of this wave is 10.1 x 10⁻²⁸J
Answer:
the potential energy a massive object has in relation to another massive object due to gravity
So I would say (a) water isn't always wet; wetness is always relative to a given substance and/or type of surface and (b) as to why it is wet when it is, presumably the answer is in terms of surface tension.
