The visible range of spectrophotometer is
In the case of visible spectrophotometers, the wavelengths measured are in the visible light range (approximately 390 – 700 nm) .
The ratio of the speed of boats ‘A’ and ‘B’ in still water is 8:9, respectively. The speed of the current is 25% of the speed of boat ‘A’ in...
The speed of a boat in still water is 8 km/hr and speed of current is 3 km/hr. If time taken to cover a certain distance upstream is 11 hours, then how ...
A car can cover a ‘2d’ km distance at the speed of ‘B’ km/h in 30 hours. The speed of the boat in still water and the speed of the stream are â€...
Speed of a boat in still water is 15 kmph and speed of stream is 12 kmph. A man rows to a place at a distance of 54 km and come back to starting point. ...
The speed of a boat in still water increases by 4 km/hour after each hour. The speed of stream is 3 km/hour. If the boat travelled 60 km in 3 hours in d...
Speed of boat is 15 km/hr. Speed of the stream is 20% less than speed of boat. Then find time taken by boat to go 108 km downstream?
A motorboat in still water travels at a speed of 36 km/hr. It goes 64 km upstream in 2 hours. The time taken by it to cover the same distance down the s...
The ratio of the speed of boats ‘A’ and ‘B’ in still water is 8:9, respectively. The speed of the current is 25% of the speed of boat ‘A’ in...
Speed of a boat in still water is 5times more than the speed of stream. If boat covers 72 km in downstream in 6 hours, then find the time taken by the b...
The combined speeds of boats 'P' and 'Q' in still water amount to 52 km/hr. The current's speed affecting boat 'P' is 25% greater than that affecting bo...
