Answer: 2.73m/s
Explanation:
Potential energy of the water is turned into kinetic energy
mgd = mv^2/2
Where m = mass of water
g = acceleration due to gravity = 9.81m/s^2
d = depth of the water = 0.38m
v = velocity of leaking water
m × 9.81 × 0.38 = mv^2/
eliminate m on both sides and multiply through by 2
7.4456 = v^2
v = sqrt(7.4456)
v = 2.73m/s
Answer:
245 m
Explanation:
v = at + v₀
50.0 m/s = a (9.8 s) + 0 m/s
a = 5.10 m/s²
x = x₀ + v₀ t + ½ at²
x = 0 m + (0 m/s) (9.8 s) + ½ (5.10 m/s²) (9.8 s)²
x = 245 m

Letter B because it is gaining more potential energy as it SLOWLY climbs up the hill.
the less motion the more potential energy there is
Given that a hot air balloon lifts 50 meters vertically into the air and then comes back down.
The displacement is the distance covered in a specific direction.
When the balloon is going up, the displacement is positive. and when the balloon is coming down, the displacement is negative.
The total displacement = 50 - 50 = 0
The distance is a measurement of length between to different points or position.
For distance, there is no need to consider direction. There is no consideration for positive or negative signs
While the distance = 50 + 50 = 100 meters
Therefore, the correct answer is C
That is, The displacement is zero and the distance is 100 meters
