Rain derops each of mass m falling from rest in air experience an upward force given by f= - bv where b is a constant and v is velocity of the drop. Using work energy theorem, derive an expression for (A) v=f(t) i.e. velocity function of time. (B) (dE)/(dt)=f(t) where E = Total machanical energy of the rain drop ( C) Draw the graphs (dE)/(dt.(dU)/(dt) and P_("viscous") as a function of time U is potential energy and P represent power ?

The following bar graph shows the marks (out of 100) of students A, B, C, D, E and F in the subjects mentioned. निम्नलिखित दंड आरेख में, वर्णित विषयों में छात्रों A, B, C, D, E और F के अंक (100 में से) दिखाए गए हैं। Based on this, only 2 students crossed the average marks in which subject: इसके आधार पर, केवल 2 छात्रों ने किस विषय में औसत अंकों को पार किया है?

The given Bar Graph presents the runs scored (A) and strike rate (B) of a batsman in live matches. Strike Rate is the number of runs scored per 100 balls faced. The strike rate (B) is taken on record only when the batsman scores at least 30 runs in a match. दिया गया दंड आरेख एक बललेबाज़ के द्वारा बनाए गए रनों ( A ) और स्ट्राइक रेट ( B ) को दर्शाता है | स्ट्राइक रेट प्रति 100 गेंदों का सामना करने पर बनाए गए रनों की संख्या है| स्ट्राइक रेट (B) को रिकॉर्ड में तभी शामिल किया जाता है जब बल्लेबाज एक मैच में कम से कम 30 रन बनाता है | How many balls did the batsman face in the third match? तीसरे मैच में बल्लेबाज़ ने कितनी गेंदों का सामना किया ?

In a modified Young's double slit experiment a monochromatic uniform and parallel beam of light of wave length 6000Å and intensity (10/pi)Wm^(-2) is incident normally on two circular apertures A and B of radii 20009Å and refractive index 1.5 for the wavelength of 6000Å is placed in front of aperture. A. Calculate the power (in watt) received at the focal spot F of the lens. The lens is symmertrically placed with respect to the apertures. Assume that 10% of the power received by each aperture goes in the originally direction and is brought to the focal spot.
