What is the difference between a CFL and an LED lamp ? 

(1) To produce light, a CFL uses mercury vapour and phosphor while an LED lamp uses semiconductor material 

(2) The average life span of a CFL is much longer than that of an LED lamp 

(3) A CFL is less energy-efficient as compared to an LED lamp 

Which of the statements given above is/are correct ? 

(a) 1 only (b) 2 and 3 only (c) 1 and 3 only (d) 1, 2 and 3

The lower end of a capillary tube is immersed in mercury. The level of mercury in the tube is found to be 2 cm below the outer level.

Rise/depression = 2S.cosθ/rρg  For mercury -0.02 = 2S'.cosθ/rρ'g  ------- (i)  For water rise, h = 2S.cos0°/rρg     ------- (ii)  Dividing (ii) by (i)  h/0.02 = -Sρ'/(S'*cosθ*ρ)  →h = -0.02*Sρ'/(1000S'.cosθ)  S' =7.5 x 10⁻²  N/m. S =...

Suppose the pressure at the surface of mercury in a barometer tube is P1 and the pressure at the surface of mercury in the cup is P2.

(a) P1= 0, P2 = atmospheric pressure EXPLANATION:   Since there is nothing above the surface of the mercury in the tube the density above this surface =0, hence the pressure P₁ =0, and...

To construct a barometer, a tube of length 1m is filled completely with mercury and is inverted in a mercury cup.

The correct answer is (d) < 76 cm. EXPLANATION:  In this case, the space above the mercury is filled with air at atmospheric pressure initially. When the cork is removed, the atmospheric...

Mention the important considerations required while fabricating a p-n junction diode to be used as a Light Emitting Diode (LED).

Important consideration in the fabrication of LED:  (a) (i) light emitting diode is a heavily doped p-n junction.  (ii) The reverse breakdown voltages of LEDs are very low, typically around 5V.  (b) The...

In a J tube partially filled with mercury the volume of an air column 4.2 ml and the mercury level in two limbs is same.

P1= 1bar= 750.12 mmHg  P2 = ( P1 ₊ h)   V1=4.2mL ,V2 =2.8mL   P1V1= P2 V2  or P2 = P1V1/ V2   = 750.12 x4.2 /2.8 =1125.18 mmHg  Now 1125.18 = 750.12 ₊ h   h = 1125.18 -750.12  =...

Assertion (A) : An iron ball floats on mercury but gets immersed in water. Reason (R) : The specific gravity of iron is more than that of mercury.

(c) Statement 1 is true but statement 2 is false. Specific gravity is the ratio of the density (mass of a unit volume) of a substance to the density (mass...
