Question
Which of the following statement is/are true?
>I. Metal oxides are acidic in nature II. Non-metallic oxides are basic in natureSolution
Metal oxides are basic in nature. Because they react with weak acids to produce salt and water, metallic oxides are basic in nature. Oxides of non – metals are acidic.
A boat travels faster than the stream by 28 km/h. It covers a distance of 112 km upstream and returns 132 km downstream, all within 7 hours. Calculate t...
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 925 km downstream is 18.5 hours. Find t...
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
A boat travelled 8km upstream in 30 minutes and 6 km downstream in 15 minutes. Then in how long it will take to go 12 km in still water?
A Man Rows upstream 48 km and downstream 72 kilometers taking 6 hours each time the speed of the current is.
The speed of boat 'X' in upstream is 18 km/hr and speed of boat 'Y' in downstream is 30 km/hr. If the difference between speeds of boat 'X' and 'Y' in s...
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...
A boat can cover 187 km in downstream in 11 hours and 180 km in upstream in 18 hours. Find the speed of boat in still water
A boat takes 3 hours to travel 24 km downstream and 4 hours to travel 16 km upstream. What is the speed of the current?
A boat takes one-third time in moving a certain distance downstream than upstream. The ratio of the speed of the boat in still water and that of the cur...
