Question

При равномерном подьеме из шахты бадьи с углем массой 10,5 т произведена работа 620 кдж какова глубина шахты

Answer 1

Н = А / F
H = A / (m*g)
H = 620000 / (10500 * 9,81) = 6 метрофф

 

Answer 2

Calculation of the Depth of the Shaft

To calculate the depth of the shaft, we can use the formula for gravitational potential energy:

Potential Energy = Mass x Gravity x Height

Given that the mass of the coal is 10.5 tons (or 10,500 kg) and the work done is 620 kJ, we can rearrange the formula to solve for height:

Height = Work / (Mass x Gravity)

The acceleration due to gravity is approximately 9.8 m/s^2.

Plugging in the values, we get:

Height = 620,000 J / (10,500 kg x 9.8 m/s^2)

Calculating this, we find that the height of the shaft is approximately 5.9 meters.

Please note that the provided search results did not contain specific information related to the given question. Therefore, the calculation above is based on the general principles of potential energy and the given values.
