Explanation:
It is given that,
Mass of concrete pilling, m = 50 kg
Diameter of wire, d = 1 mm
Radius of wire, r = 0.0005 m
Length of wire, L = 11.2
Young modulus of steel, 
The young modulus of a wire is given by :
So, the wire will stretch 0.034 meters. Hence, this is the required solution.
Gravity is the cause of formation waves.
I think its
Mass and volume
Answer:
The value is 
Explanation:
From the question we are told that
The wavelength is 
The distance of separation is 
The distance from the screen is 
Generally the separation between the adjacent bright fringe is mathematically represented as
=> 
=>
<span>The ability to navigate, hunt, and communicate by electric current in water most likely helps make up for the effect of vision. The answer to your question is VISION.
</span>If fish live in a dark, murky water, that means that their sense of vision is affected. In dark, murky water they could not see anything. So, fish that lives in this kind of water developed the ability to <span>o navigate, hunt, and communicate by electric current in water. This ability is known as electroreception. Among fish, electroreception is present in some sharks and rays, and electric eels.</span><span>
I hope that this is the answer that you were looking for and it has helped you.
