Mass of the sound reflector is given as
mass of the chain itself is
now here since this system is suspended at rest and no acceleration is given for the system so in order to find the tension in the chain we will just use force balance equation
As per force balance we can say that weight of the chain and reflector downwards will be counter balanced by tension in the string
Now here we will have
since chain is given with some mass so tension at the top end of the chain will be
So here tension in the chain will be 1744.4 N at the top end and this tension will decrease as we move down along the length of the chain.
Answer:
Wave speed is related to both wavelength and wave frequency. Wavelength is the distance between two corresponding points on adjacent waves. Wave frequency is the number of waves that pass a fixed point in a given amount of time. This equation shows how the three factors are related:
Speed = Wavelength x Wave Frequency
Explanation:
Scientists could explore Europa’s oceans by using potent technologically advanced telescopes capable of deciphering the content beneath the ice crust.
<h3>What are potent technologically advanced telescopes?</h3>
The latest technologically advanced telescopes are potent optical devices that allow us to discover the presence of certain compounds not only in the atmosphere of other planets in the solar system but also the content on the surface (e.g, the water content).
These telescopes contain curved mirrors that gather and focus different spectra of light from the sky such as the Webb telescope which was launched by NASA in the final of 2021.
Therefore, with this data, we can see that technologically advanced telescopes are potent optical instruments that can be used to observe the presence of different compounds including water on the surface of a planet or its satellites such as in the case of Europe which is a satellite of Jupiter.

Answer A
Explanation: because u need to make sure you know the difference between a need and a want
The index of refraction of a material is the ratio between the speed of light in vacuum and the speed of light in that material:
where
n is the refractive index
is the speed of light in vacuum
v is the speed of light in the material
For sapphire, n=1.76, so if we re-arrange the previous equation and we use this value, we can calculate the speed of light in sapphire:
