The mass of the water in the container is 10,104.00 kg.

A schematic diagram of a piston-cylinder apparatus is shown in the adjoining image.

In the above case, the atmospheric pressure applied by the piston and the weight of the piston should balance the weight of the water inside the container

Hence,

Atmospheric Pressure x Area of Piston + Mass of piston x g = Mass of water x g

101 x 10^3 x pi x (2.5 x 10^-2)^2 + 4 x 10 = Mass of water x 10

Mass of water x 10 = 101,040.001

Mass of Water = 101,040.001/10

Mass of Water = 10,104 kg

Hence, the mass of the water in the container is 10,104.00 kg.

What two gases probably dominated precambrian earth's atmosphere?
galben [10]
I think these gases are water vapor and nitrogen. As the temperature rises, these water vapor molecules, would condense and form the oceans we have. Also, it was said that in the early atmosphere, nitrogen is very abundant and even today the composition of air is 79% by volume.

A parallel-plate capacitor has area A and plate separation d, and it is charged to voltage V. Use the formulas from the problem
Shtirlitz [24]

Answer:

U = (ε0AV^2) / 2d

Explanation:

Where C= capacitance of the capacitor

ε0= permittivity of free space

A= cross sectional area of plates

d= distance between the plates

V= potential difference

First, the capacitance of a capacitor is obtained by:

C = ε0A/d.

Starting at the formula , U= (CV^2)/2. Formula for energy stored in a capacitor

Substitute in for C:

U = (ε0A/d) * V^2 / 2

Hence:

U = (ε0AV^2) / 2d

arlik [135]

Answer:

14.36m/s

Explanation:

From the law of conservation of linear momentum

m1u1 + m2u2 = v(m1 + m2)

68×17 + 76×12= v(68+76)

1156+912 = 144v

2068 = 144v

v = 2068/144

=14.36 m/s

A uniform plank of mass 10kg and length 10m rests on two supports, A and B as shown. A boy of weight 500N stands at a distance o
kifflom [539]

Answer:

U² = 142.86 N

U¹ = 357.14 N

Explanation:

Taking summation of the moment about point A, we get the following equilibrium equation: (taking clockwise direction as positive)

W(2\ m) - U^2(7\ m) = 0

where,

W = weight of boy = 500 N

U² = reaction ay B = ?

Therefore,

(500\ N)(2\ m)-(U^2)(7\ m)=0\\U^2=\frac{1000\ Nm}{7\ m}\\

<u>U² = 142.86 N</u>

Now, taking summation of forces on the plank. Taking upward direction as positive, for equilibrium position:

W-U^1-U^2=0\\500\ N - 142.86\ N = U^1\\

<u>U¹ = 357.14 N</u>
