If the binding energy per nucleon of the product nucleus is higher than that of the reactants, it means the product is more stable. The total binding energy increases, and the mass of the final nucleus is less than the mass of the initial system. This mass difference is released as energy, known as the Q-value of the reaction. Therefore, such a process is exothermic, and energy is released.
The speed of the boat in still water is 10 km/hr and the speed of the stream is 5 km/hr. A boat goes 75 km downstream with its usual speed but at the ti...
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 downstream and upstream is 30 km/hr and 22 km/hr, respectively. Find the approximate time taken by the boa...
The speed of the boat upstream and downstream are in the ratio of 3:4. If the boat covers a distance of 147 km in still water in 7 hours, determine the...
A boy can swim in water with a speed of 12 km/hr in still water. If the speed of the stream is 4 km/hr, what will be the time taken by the boy to cover ...
A motorboat covers a certain distance downstream in a river in 3 hours. It covers the same distance upstream in 3 and a half an hour. If the speed of th...
"A boat takes 60 seconds to travel ______ metres downstream and 40 seconds to travel ______ metres upstream in the same river. The speed of the stream i...
A boat can cover 180 km in downstream in 18 hours and 125 km in upstream in 5 hours. Find the distance travelled by the boat in still water in 10 hours.
If a river is flowing at a rate of 6 km/hr and a boat's speed in still water is 150% higher than the river's speed, and the boat travels 'd' kilometers ...
Speed of a boat in still water is three times the speed of the boat in upstream. If the boat takes 20 minutes to cover 15 km in downstream, then find th...
