Answer:

D. F = 24000[N]

Explanation:

To be able to calculate the force we must first find the pressure at the bottom of the tank. By means of the following equation:

P=Ro*g*h

where:

Ro = density of the liquid = 800 [kg/m³]

g = gravity acceleration = 9.81 [m/s²]

h = elevation = 1.2 [m]

P=800*9.81*1.2\\P=9417.6[Pa]

Pressure is defined as the relationship between Force on the area.

P=F/A\\F=9417.6*2.5\\F = 23544 [N] = 24000[N]

Help with this question please.
mr Goodwill [35]

There are 4 hydrogens on the right side (2\mathrm H_2=4\mathrm H), and 2 hydrogens on the left per molecule of \mathrm H_2. To get the same number of hydrogens on both sides, the coefficient should be 2.

(Then the number of oxygens will be consistent, since 2\mathrm H_2\mathrm O contributes 2 oxygens, and so does \mathrm O_2.)

A 117 kg horizontal platform is a uniform disk of radius 1.61 m and can rotate about the vertical axis through its center. A 62.
Ivenika [448]

Answer:

I_syst = 278.41477 kg.m²

Explanation:

Mass of platform; m1 = 117 kg

Radius; r = 1.61 m

Moment of inertia here is;

I1 = m1•r²/2

I1 = 117 × 1.61²/2

I1 = 151.63785 kg.m²

Mass of person; m2 = 62.5 kg

Distance of person from centre; r = 1.05 m

Moment of inertia here is;

I2 = m2•r²

I2 = 62.5 × 1.05²

I2 = 68.90625 kg.m²

Mass of dog; m3 = 28.3 kg

Distance of Dog from centre; r = 1.43 m

I3 = 28.3 × 1.43²

I3 = 57.87067 kg.m²

Thus,moment of inertia of the system;

I_syst = I1 + I2 + I3

I_syst = 151.63785 + 68.90625 + 57.87067

I_syst = 278.41477 kg.m²

Explain why ventilation is very important if there is risk of exposure to random gas in your home school
bonufazy [111]
Ventilation is very important because it helps remove the gas form people’s homes and schools and it redirects the random gas outside so it is less likely to hurt people
