Is = NBA/C Voltage sensitivity Vs = NBA/CRG So, resistance of galvanometer RG = Is/Vs = (9 × 1)/(30 × 10-3) = 9000/30 = 300 Ω
A boat travels 315 km downstream in 7 hours and 135 km upstream in 9 hours. Determine the total time the boat takes to cover 150 ...
A man can row one quarters of a kilometer against the stream in 30/4 minutes and return in 5/2 minutes. The speed of the man in still water is:
Speed of a boat in still water is 12 kmph and speed of stream is 9 kmph. A man rows to a place at a distance of 63 km and come back to starting point. T...
The speed of current is 30 km/hr. If the speed of the boat in still water had been 13 km/hr more than the original speed then it would take 7.5 hours to...
A boat running downstream covers a distance of 56 km in 7 hrs and covering the same distance upstream in 14 hrs. What is the speed of a boat in still wa...
Speed of a boat in still water to speed of boat in upstream is 10:7. If the boat can travel 390 km in downstream in 5 hours, then find the time taken by...
The speed of the stream is 12 km/h. Boat ‘A’ covers 160 km distance against the stream in 8 hours and boat ‘B’ covers 84 km distance against the...
A boat can travel 10 km more in downstream than that in upstream, in 5 hours while the difference between the time taken by the same boat to travel 250 ...
The speed of a boat in still water is three times the speed of the boat upstream. If the boat takes 30 minutes to cover 27 km downstream, then find the ...
A boat moves 25km upstream and 39km downstream in 8 hours. It travels 35km upstream and 52km downstream in 11 hours. What is the speed of the stream if ...
