Explanation:
A wave on a string is described is given by :
![D(x,t)=2\ cm\ sin[(12.57\ rad/m)-(638\ rad/s)t]](https://tex.z-dn.net/?f=D%28x%2Ct%29%3D2%5C%20cm%5C%20sin%5B%2812.57%5C%20rad%2Fm%29-%28638%5C%20rad%2Fs%29t%5D)
The linear density of the string is 5 g/m.
Where
x is in meters and t is in seconds
The general equation of a wave is given by :
(2) The speed of the wave in terms of tension is given by :
Also, 
So, 
T = 12.88 N
(3) The maximum displacement of a point on the string is equal to the amplitude of the wave. So, the maximum displacement is 2 cm.
(4) The maximum speed of a point on the string is given by :
v = 12.76 m/s
Hence, this is the required solution.
The heat and energy of coal burning is more easier and more efficient to turn into electricity than any method using renewable resources.
If you mean what F=ma is then it is Force equals mass times acceleration.<span>Force equals mass times acceleration is ur answer</span>
Explanation:
a block of iron in denser then the block of wood
as the atoms in iron are more closely bounded as compared to that in the wood
if both are drop in water iron block sink to bottom while float on the level
Answer:
Direction
Explanation:
A vector is a geometrical representation of physical quantity. It has a particular direction with a specific magnitude.
In the geometry of space whether it is two dimensional or three dimensional the vector quantity has a specific direction. Such as a stone is thrown with a velocity in a particular direction.
The path of the stone in three-dimension shows its direction and speed is its magnitude.
Hence, the velocity of stone has two property magnitude mentioned as speed and particular direction.
On writing the mathematical expressions for vectors, it is denoted by arrow mark on its top as shown below.
