Answer:
2100 kg*m/s
Explanation:
The proper term for power in this case is to use the physics term "impuls" = p.
1. Find the "power" developed by the gun to fire just 1 bullet.
2. multiply by 60 to find the power produced by the gun per minute.
p = m * v
where
m = mass of the bullet = 50 g = 0.050 kg
v = velocity of the bullet = 700 m/s
p = 0.050 * 700
p = 35 kg*m/s
So the impuls for 1 bullet is 35 kg*m/s
The gun can fire 60 bullets per minute so it's fireing power must there fore be 60 * 35 = 2100 kg*m/s
Sodium, magnesium, and aluminum!
This causes the fluid to increase its speed. Bernoulli's principle tells us that an increase in the speed of a fluid happens at the same time with a reduction in pressure or a reduction in the fluid's potential energy. This necessitates that the amount of kinetic energy, potential energy and internal energy stays persistent.

Answer: Fnet = 40 N on the right
Explanation: The net force is the summation of forces acting on an object. Add the forces in the same direction and subtract to the opposing force moving in the opposite side.
Fnet= F1 + F2 - F3
= 120 N + 60 N - 140 N
= 180 N - 140 N
= 40 N on the right
