Mr. Miles zips down a water-slide starting at 15 m vertical distance up the scaffolding. Disregarding friction, what is the velo
lilavasa [31]

Answer:

The velocity of the Mr. miles is 17.14 m/s.

Explanation:

It is given that,

Mr. Miles zips down a water-slide starting at 15 m vertical distance up the scaffolding, h = 15 m

We need to find the velocity of the Mr. Miles at the bottom of the slide. It is a case of conservation of energy which states that the total energy of the system remains conserved. Let v is the velocity of the Mr. miles. So,

v=\sqrt{2gh}

g is the acceleration due to gravity

v=\sqrt{2\times 9.8\times 15}

v = 17.14 m/s

So, the velocity of the Mr. miles is 17.14 m/s. Hence, this is the required solution.

A vessel with an unknown volume is filled with 10 kg of water at 90oC. Inspection of the vessel at equilibrium shows that 8 kg o
damaskus [11]

Hey there!

In this case, it is possible to solve this problem by using the widely-known steam tables which show that at 90 °C, the pressure that produces a vapor-liquid mixture at equilibrium is about 70.183 kPa (Cengel, Thermodynamics 5th edition).

Moreover, for the calculation of the volume, it is necessary to calculate the volume of the vapor-liquid mixture, given the quality (x) it has:

x=\frac{m_{steam}}{m_{total}}

Thus, since 8 kg correspond to liquid water, 2 kg must correspond to steam, so that the quality turns out:

x=\frac{2kg}{10kg} =0.20

Now, at this temperature and pressure, the volume of a saturated vapor is  2.3593 m³/kg whereas that of the saturated liquid is 0.001036 m³/kg and therefore, the volume of the mixture is:

v=0.001036m^3/kg+0.2(2.3593-0.001036 )m^3/kg=0.4727m^3/kg

This means that the volume of the container will be:

V=10kg*0.4727m^3/kg\\\\V=4.73m^3

Regards!

Georgia [21]
Rod is 450mm and disk has a radius of 75mm So there is a pin holding the assembly upwards which is when Θ=0 and at the pin there is a torsional spring with constant of k=20N m/rad. One end of the rod is attached to the pin and the other is attached to the disk.

g A hydraulic press has a safety feature which consists of a hydraulic cylinder with a piston at one end and a safety valve at t
nlexa [21]

Answer:

58.32 N

Explanation:

Area of a circle = \pir^{2}

where r is the radius of the circle.

The cylinder has a radius of 0.02 m, its area is;

A_{1} = \pir^{2}

  = \frac{22}{7} x (0.02)^{2}

  = \frac{22}{7} x 0.0004

  = 1.2571 x 10^{-3}

Area of the cylinder is 0.0013 m^{2}.

The safety valve has a radius of 0.0075 m, its area is;

A_{2} = \pir^{2}

    = \frac{22}{7} x (0.0075)^{2}

    = \frac{22}{7} x 5.625 x 10^{-5}

    = 1.7679 x 10^{-4}

Area of the valve is 0.00018 m^{2}.

From Hooke's law, the force on the safety valve can be determined by;

F = ke

F_{2}  = 950 x 0.0085

  = 8.075 N

Minimum force, F_{1}, required can be determined by;

\frac{F_{1} }{A_{1} } = \frac{F_{2} }{A_{2} }

\frac{F_{1} }{0.0013} = \frac{8.075}{0.00018}

F_{1} = \frac{0.0013 *8.075}{0.00018}

    = 58.32

The minimum force that must be exerted on the piston is 58.32 N.
