water in a canal , 6m wide and 1.5m deep , flowing with a speed of 10km/h . How much area will it irrigate in 30 minutes , if 8 cm of standing water is needed.

Hope this helps

Explanation:

6m times 1.5m= 9m

9m + 8cm= 9.08 meters

9.08meters times 10km/h= 25.2 m/s

25.2 m/s the area will irrigate in 30 minutes

the correct answer option is: weapons.

explanation:

tensions rose as the two opposing superpowers competed for 'weapons'.

referring to the cold war (1945-1991), the two superpowers, usa and ussr, experienced a phase of struggle and conflict with each other. these two superpowers considered each other as a threat to their survival and thus opted for policies to strengthen their positions.

the two superpowers never went to war with each other directly but competed for weapons to preserve their positions.

a case involving the laws of a single state.
