A person lifts a bucket of water weighing 12 kg from a well 10 m deep in 15 seconds. What power does it develop at the same time?
To find the value of the power developed by the specified person when lifting the bucket, we apply the formula: N = A / t = m * g * h / t.
Variables and constants: m is the mass of the bucket being lifted (m = 12 kg); g – acceleration due to gravity (g ≈ 9.8 m / s2); h – well depth (h = 10 m); t is the duration of the bucket lifting (t = 15 s).
Calculation: N = m * g * h / t = 12 * 9.8 * 10/15 = 78.4 W.
Answer: The power that the specified person has developed is 78.4 watts.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
