Q:

At 3.40, the hour hand and the minute hand of a clock form an angle of:

A) 120 degrees	B) 125 degrees
C) 130 degrees	D) 135 degrees

Answer & Explanation Answer: C) 130 degrees

Explanation:

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

Angle traced by it in 11/3 hrs= ${(\frac{360}{12} * \frac{11}{3})}^{°}$ = $110^{°}$

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.

SI unit of equivalent conductance

A) ohm/cm	B) Siemens m2/equivalent
C) Siemens/equivalent	D) mho/cm

Answer & Explanation Answer: B) Siemens m2/equivalent

Explanation:

SI_unit_of_equivalent_conductance1556274980.jpg image

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 $m^{3}$

Now, required equivalent conductance unit is $Siemens . m^{2} / equivalent$ .
