Question

При равномерном подъёме из колодца ведра воды массой 10кг была совершена работа 650 Дж. Какова глубина колодца?​

Answer 1

Ответ: 6,5м

Объяснение:

Дано:

m=10кг

А=650Дж

-----------------

h-?

А=Fh

h=A/F=F/(mg)=650/(10*10)=6,5м

Answer 3

Calculating the Depth of the Well

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

Gravitational Potential Energy (GPE) = mgh

Where: - m = mass of the object (in this case, the bucket of water) = 10 kg - g = acceleration due to gravity = 9.81 m/s^2 (approximate value on the surface of the Earth) - h = height or depth

We are given that the work done is 650 J. The work done in lifting the bucket of water is equal to the change in gravitational potential energy.

Calculation

We can use the given work done to find the height (depth) of the well using the formula:

Work done = GPE = mgh

h = Work done / (mg)

Substitute the given values: h = 650 J / (10 kg * 9.81 m/s^2)

Calculating the value of h: h ≈ 6.63 meters

So, the depth of the well is approximately 6.63 meters.
