Answer:
<em>500Hertz</em>
Explanation:
Given the fundamental frequency of the string given as 1.25x10²Hz
Harmonics are integral multiples of the fundamental frequency.
In strings, the third harmonic F3 is expressed in terms of the fundamental frequency expressed as;
F3 = 4F0
F0 is the fundamental frequency;
Given
F0 = 1.25x10²Hz
F3 = 4(1.25x10²)
F3 = 4(125)
F3 = 500Hz
<em>Hence the frequency of the third harmonic is 500Hertz</em>

Answer:
well you can get it from light mostly sunlight but normal light bulbs they actully stop the radiation from going in those so thats actually false

Explanation:
The gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Mathematically, it is given by :
...............(1)
Where m₁ and m₂ are masses
r is the distance between them
It is clear from equation (1) that :
1. The gravitational force between two objects is inversely proportional to the square of the distance between the two objects.
2. The gravitational force between two objects is proportional to the product of the masses of the two objects.
Hence, this is the required solution.
Explanation:
The observation from the gold foil experiment by Rutherford was that, while most of the alpha particles went through the foil almost unaffected, a small fraction of the particles were deflected in directions with large angles away from the original path (including bouncing straight back). This was unexpected and led to a complete revision of the model (as relates to your part 1).
The nuclear model proposes a spacially small but massively charged nucleus. Due to its small size, most alpha particles will pass through the atoms of the gold foil unaffected (they "miss" the small nucleus). But some of them will come very close to the nucleus and those will be deflected strongly by its charge. This is one of the main arguments explaining the observation and speaking for the validity of the nuclear model.
