Answer:
The time taken by spider to catch insect 1.5 ms
Explanation:
Given:
Linear mass density
![\frac{kg}{m}](https://tex.z-dn.net/?f=%5Cfrac%7Bkg%7D%7Bm%7D)
Tension on the string
N
Distance between web and insect lands
m
From the formula of velocity in string,
![v = \sqrt{\frac{T}{\mu} }](https://tex.z-dn.net/?f=v%20%3D%20%5Csqrt%7B%5Cfrac%7BT%7D%7B%5Cmu%7D%20%7D)
First find the velocity and then find time,
![v = \sqrt{\frac{0.40}{1 \times 10^{-5} } }](https://tex.z-dn.net/?f=v%20%3D%20%5Csqrt%7B%5Cfrac%7B0.40%7D%7B1%20%5Ctimes%2010%5E%7B-5%7D%20%7D%20%7D)
![\frac{m}{s}](https://tex.z-dn.net/?f=%5Cfrac%7Bm%7D%7Bs%7D)
The time taken is given by,
![v = \frac{x}{t}](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7Bx%7D%7Bt%7D)
![t = \frac{x}{v}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7Bx%7D%7Bv%7D)
![t = \frac{30 \times 10^{-2} }{200}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B30%20%5Ctimes%2010%5E%7B-2%7D%20%7D%7B200%7D)
sec
ms
Therefore, the time taken by spider to catch insect 1.5 ms
<span>When stars are moving away (red shift) the wavelength increases and thus the object looks more reddish (Because red color has longer wavelengths). As opposed to when the star is moving closer the wavelength contracts (blue shift) and the object appears slightly blue. So, the statement is False.</span>
1) I think its biomass which still pollutes the air.
2)gamma rays
Engines can overheat for many reasons. In general, it's because something's wrong within the cooling system and heat isn't able to escape the engine compartment. The source of the issue could include a cooling system leak, faulty radiator fan, broken water pump, or clogged coolant hose.
Hope it helps! Have a nice day or night!
I believe a longitudinal wave goes side to side.
