Ответ:
166.67 N
Explanation:
Given:
Mass flow rate = 50 kg/min = 50 kg / 60 seconds = 0.833 kg/s
Initial velocity = 200 m/s
after striking the normal board the water will flow in the normal direction, thus the final velocity in the direction of the initial flow will be zero
therefore,
Force = (change in momentum)
or
Force = Initial momentum - final momentum
or
Force = 0.833 × 200 - 0.833 × 0
or
Force = 166.67 N

I would consider the practice of "ghost hunting” to be closer to pseudoscience than science because the work described in the article mostly lacks process and is subjective. In the article, people looking for evidence of ghosts do not set up controlled experiments with repeated trials. Instead, they take several measurements and make guesses about what might be causing the results they see. The people in the article also base conclusions on observations such as feeling a "heavy presence” or a "sudden chill.” These are subjective observations.
