The frozen balloon shrank because the average kinetic energy of the air molecules in a balloon decreases when the temperature decreases. This makes the molecules move more slowly and have less frequent and weaker collisions with the inside wall of the balloon, which causes the balloon to shrink a little. This can be called contraction.
I am unable to see the attachment pm me and i can help you
Answer:
λ = 521nm
Explanation:
To convert wavelength to frequency we need to use the equation:
ν = c / λ
<em>Where ν is frequency: 5.76x10¹⁴s⁻¹;</em>
<em>c is speed of light: 3x10⁸ms⁻¹; </em>
<em>And λ is wavelength in m:</em>
Wavelength is:
λ = c / ν
λ = 3x10⁸ms⁻¹ / <em>5.76x10¹⁴s⁻¹</em>
λ = 5.21x10⁻⁷m
= 521nm

Answer:
Proton: m= 1.6726x10⁻²⁷ kg
Neutron: m= 1.6749x10⁻²⁷ kg
Electron: m= 9.1164x10⁻³¹ kg
Explanation:
<u>We can calculate the mass of a proton, neutron, and electron using the following data:</u>
<em>mass of proton</em>: 1.00728 amu
<em>mass of neutron</em>: 1.00867 amu
<em>mass of electron</em>: 5.49x10⁻⁴ amu
<em>1 amu</em> = 1.66054x10⁻²⁷ kg
Now, the mass of a proton, neutron, and electron in kilograms can be calculated using the next relation:
![m = 1.66054 \cdot 10^{-27} \frac{kg}{amu} \cdot particle's mass (amu)](https://tex.z-dn.net/?f=%20m%20%3D%201.66054%20%5Ccdot%2010%5E%7B-27%7D%20%5Cfrac%7Bkg%7D%7Bamu%7D%20%5Ccdot%20particle%27s%20mass%20%28amu%29%20)
For the proton:
![m = 1.66054 \cdot 10^{-27} \frac{kg}{amu} \cdot 1.00728 amu = 1.6726 \cdot 10^{-27} kg](https://tex.z-dn.net/?f=%20m%20%3D%201.66054%20%5Ccdot%2010%5E%7B-27%7D%20%5Cfrac%7Bkg%7D%7Bamu%7D%20%5Ccdot%201.00728%20amu%20%3D%201.6726%20%5Ccdot%2010%5E%7B-27%7D%20kg%20)
For the neutron:
![m = 1.66054 \cdot 10^{-27} \frac{kg}{amu} \cdot 1.00867 amu = 1.6749 \cdot 10^{-27} kg](https://tex.z-dn.net/?f=%20m%20%3D%201.66054%20%5Ccdot%2010%5E%7B-27%7D%20%5Cfrac%7Bkg%7D%7Bamu%7D%20%5Ccdot%201.00867%20amu%20%3D%201.6749%20%5Ccdot%2010%5E%7B-27%7D%20kg%20)
For the electron:
