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:
The ratio is 4
Explanation:
The moment of inertia of a solid sphere about a central axis is:
With m the mass and r the radius of the sphere.
For the smaller sphere with mass M and radius R the moment of inertia is:
(1)
For the bigger sphere with mass M and radius 2R the moment of inertia is:
(2)
The ratio between larger of the larger sphere's moment of inertia about a central axis to that of the smaller sphere is the ratio between (2) and (1):
The term cancels, so:
In
the 1980s, the campaign for homosexual rights received government support as Mel
Boozer, an openly gay running vice-presidency, gave a Democratic National
Convention speech at the same time Scotland legalized male to male sexual
behaviors. On 1981, the World Health Organization (WHO) removed homosexuality as
a mental illness.
<span>bullet In July, the Centers for Disease Control
reported that 26 cases of a very rare form of cancer, Kaposi's Sarcoma, was
found in young gay men. This was later recognized as being due to the presence
of AIDS.</span>
