A house at the bottom of a hill is fed by a full tank of water 5m deep and connected to the house by a pipe that is 110m long at

yawa3891 [41]

Answer:

a) $p=964178.7\ Pa$

b) $h=98.2853\ m$

Explanation:

Given;

depth of the water-tank, $d=5\ m$

length of the pipe, $l=110\ m$

inclination of the pipe from the horizontal, $\theta =58^{\circ}$

Now the effective vertical height of the water column from the free surface of the water to the bottom of the pipe at house:

$h=d+l.\sin\theta$

$h=5+110\sin58$

$h=98.2853\ m$

Now the pressure due to effective water head:

$p=\rho.g.h$

where:

$\rho=$ density of the liquid, here water

$g=$ acceleration due to gravity

$h=$ height of the liquid column

$p=1000\times9.81\times 98.2853$

$p=964178.7\ Pa$

Now the height of water corresponding to this pressure will be the same as the effective water head by the law of conservation of energy.

$h=98.2853\ m$

A physical pendulum in the form of a planar object moves in simple harmonic motion with a frequency of 0.290 Hz. The pendulum ha

BARSIC [14]

Answer:

1.4584 kg $m^2$

Explanation:

Time period of a physical pendulum is given by $T=2Π\sqrt{\frac{I}{mgd}}$

Here f=0.290 so $T=\frac{1}{F}=\frac{1}{0.29}=3.44827$

Mass =2.40 kg

d=0.300 m

g =9.8 m $sec^2$

So $3.448=2\times \pi \sqrt{\frac{I}{2.4\times 9.81\times 0.300}}=1.4584$ kg- $m^2$

So the moment of inertia of the pendulum about the pivot point will be 1.4584 kg- $m^2$

Identify the position where the cyclist has maximum kinetic energy.

finlep [7]

You need the picture. However, since I'm doing PLATO as well, here's the answer:

The third position in which the cyclist is going downhill is the position where the cyclist has the maximum kinetic energy. The other two photos show that the biker has more potential energy.

Thanks, let me know if this helped!
