A 10-mm-diameter cable is strung between a series of poles that are 50 m apart. Determine the horizontal force this cable puts on each pole if the wind velocity is 34 m/s.

The value is  

Explanation:

From the question we are told that

   The diameter is  

    The distance between the poles is  L =  50 m

      The velocity of the wind is  

Generally the horizontal force the cable puts on each other is mathematically represented as

Here A is the area of the rope(i.e assuming the rope to be a cylinder ) which is mathematically represented as

=>  

=>  

Here is the coefficient of discharge of the rope and the value is  

          is the density of air with value  

 So

=>  

=>  

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
