Answer:
The value is
Explanation:
From the question we are told that
The mass of the stone is
The radius of the circle is
The angular speed is
Generally the tension in the string is mathematically represented as
=>
=>
Frequency and wavelength are two variables which are
indirectly proportional.
They are related in the following equation:
f = c / w
Where,
<span>f = frequency c =
speed of light w = wavelength</span>
Since c is constant, we can equate condition 1 and
condition 2:
f1 w1 = f2 w2
When w2 = 3 w1, then f2 becomes:
261.63 w1 = f2 (3 w1)
Cancelling w1:
f2 = 261.63 / 3
<span>f2 = 87.21 Hz</span>
A prism is a piece of glass or plastic in the shape of a triangle. A prism works because the different colors of light travel at different speeds inside the glass. Because the colors of light travel at different speeds, they get bent by different amounts and come out all spread out instead of mixed up.
Refraction is the bending of a wave when it enters a medium where its speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media. Refraction is responsible for image formation by lenses and the eye.
Answer:
Hey
on August 6, 1945, the atomic bomb was released. the only remains of the poor people in Hiroshima were the shadows of the last place they stood.
The energy that was released by the atomic bomb was transferred by nuclear fission (The processes at which atoms split and give off energy).
In the core of the sun, the process is different from that of fission. it is called nuclear fusion (the process in which atoms [of hydrogen] are smashed together into helium and release tremendous amounts of energy).
