What is the purpose of a transistor in a circuit?
To amplify or switch electronic signals
The ratio of the speed of boat ‘A’ in still water, the speed of boat ‘B’ in still water and the speed of the current is 7:5:2, respectively. If ...
A man can row at 6 kmph in still water. If the velocity of current is 4 kmph and it takes him 6 hour to row to a place and come back, how far is the place?
A boat covers 13 km upstream in 52 min. If the speed of the current is 3 km / h, then in how much time will it cover 40 km downstream?
A boat goes 56 km in upstream in 4 hours and takes 3 hours to complete a distance of 18 km in downstream. Find the speed of boat in still water.
A boat goes 50 km in upstream in 5 hours and takes 4 hours to complete a distance of 16 km in downstream. Find the speed of boat in still water.
The speed of a boat in still water is 6 km/hr more than that of the current. The time taken by the boat to cover 875 km downstream is 17.5 hours. Find t...
The ratio of the speed of a boat in still water to its speed in downstream is 6:8. If the difference between the time taken by the boat to travel 288 km...
A Boy can swim 12 km/hr in still water. If the velocity of the stream is 6 km/hr, the time taken by him to swim a place 28 km upstream and back is
The speed of Boat is given as 20 km/hr and 28 km/hr while travelling to Upstream and downstream individually.Then, the boat travelled for ‘T’ hours ...
The duration it takes for boat 'P' to cover 160 km downstream is equal to the duration it takes to cover 120 km upstream. If the ratio of the speed of b...
