Answer:
I think it's 2 the photo is hard to tell what they are exactly talking about.
Yes you need the light or just go outside to get it from the sun
Answer:
A. Voltage
Explanation:
I got a 100% on the quiz on edg so trust me
A. Neutrons.
If it were electrons, it would be an ion.
If it were protons, it wouldn't be the same element.
Answer:
a. The angular frequency is doubled.
e. The period is reduced to one-half of what it was.
Explanation:
Angular frequency is given as;
ω = 2πf
![\frac{\omega _1}{f_1} = \frac{\omega _2}{f_2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Comega%20_1%7D%7Bf_1%7D%20%3D%20%5Cfrac%7B%5Comega%20_2%7D%7Bf_2%7D)
when the frequency is doubled
![\frac{\omega _1}{f_1} = \frac{\omega _2}{(2f_1)} \\\\\omega _1 = \frac{\omega _2}{2}\\\\\omega _2 = 2\omega _1](https://tex.z-dn.net/?f=%5Cfrac%7B%5Comega%20_1%7D%7Bf_1%7D%20%3D%20%5Cfrac%7B%5Comega%20_2%7D%7B%282f_1%29%7D%20%5C%5C%5C%5C%5Comega%20_1%20%3D%20%5Cfrac%7B%5Comega%20_2%7D%7B2%7D%5C%5C%5C%5C%5Comega%20_2%20%3D%202%5Comega%20_1)
Thus, the angular frequency will be doubled.
Amplitude in simple harmonic motion is the maximum displacement.
Frequency is related to period in simple harmonic motion as given in the equation below;
![f = \frac{1}{T} \\\\f_1T_1= f_2T_2\\\\T_2 = \frac{f_1T_1}{f_2}](https://tex.z-dn.net/?f=f%20%3D%20%5Cfrac%7B1%7D%7BT%7D%20%5C%5C%5C%5Cf_1T_1%3D%20f_2T_2%5C%5C%5C%5CT_2%20%3D%20%5Cfrac%7Bf_1T_1%7D%7Bf_2%7D)
when the frequency is doubled;
![T_2 = \frac{f_1T_1}{2f_1} \\\\T_2 = \frac{T_1}{2}](https://tex.z-dn.net/?f=T_2%20%3D%20%5Cfrac%7Bf_1T_1%7D%7B2f_1%7D%20%5C%5C%5C%5CT_2%20%3D%20%5Cfrac%7BT_1%7D%7B2%7D)
Thus, the period will be reduced to one-half of what it was.
