The Canadair CL415 is a rescue and fire-fighting aircraft of the Civil Protection; it is able to collect water from the sea or lakes to discharge it on the fire front. During the filling phase it flies on the surface of the water at 130 km / h and in 12 seconds it charges 6100 L of water. Calculate the impulse and the additional mean force
which must supply its engines during a
filling.

show explanation ​

which three statements are true about all alloys?

we need to know the time interval during which the force acts. impulse of force = momentum change

the answer is a. hope this .

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
