Angle traced by hour hand in 12 hrs. = 360º.

Angle traced by it in  11/3 hrs=  36012*113°=110°

Angle traced by minute hand in 60 min. = 360º.

Angle traced by it in 40 min. =(360/60*40)°=240°

  Required angle (240 - 110)º = 130º.

Communication by touch is called Haptics communication and the study of this is called as Haptics.

Stars are what that come out at night without being called and are lost in the day without being stolen.

Equivalent conductance is defined as the conductance of an electrolyte solution containing one gram equivalent of the electrolyte. It is equal to the product of specific conductance (k) of the solution and the volume (V) of the solution that contains one gram equivalent of the electrolyte.

 λ = k x V

Unit of spceific conductance k is Siemens / m.

Volume of the solution V is m3

Now, required equivalent conductance unit is Siemens.m2/equivalent.

In colder clouds: droplets formed by Bergeron mechanism. But, in many parts of the world the air is too warm for ice crystals to form. This being the case, rain and snow cannot develop following the Bergeron Process. Instead, tiny droplets form as they collide into one another creating larger and larger droplet, this is known as collision-coalescence process. So, warmer clouds are associated with this keyword.
