Answer and Explanation:

Some of the advantages of direct water supply system are:

Smaller size of the cistern
No risk of polluted water
Ease of installation
Lower pipe work

Some of the advantages of indirect water supply system are:

It can be pumped completely
Lower demand on the main source
Minimization of wear and tear on taps
Larger size of the cistern.

Answer:

Direct water supply system:

1. Smaller cold water cistern.

2.Less costly system

3.Smaller storage cistern and required less pipe work

4.Drinking water can be available at the wash basin

Indirect water supply system:

1.First water stored in the stored tank then come out to from the stored tank.That is why it produce less noise.

2.Large quantity of water can stored.

3.Pressure is low in the pipe because water did not come out directly from the main line.

4.it prevent water from become dirty.

A 60-cm-high, 40-cm-diameter cylindrical water tank is being transported on a level road. The highest acceleration anticipated i

dlinn [17]

Answer:

$h_{max} = 51.8 cm$

Explanation:

given data:

height of tank = 60cm

diameter of tank =40cm

accelration = 4 m/s2

suppose x- axis - direction of motion

z -axis - vertical direction

$\theta$ = water surface angle with horizontal surface

$a_x =$ accelration in x direction

$a_z =$ accelration in z direction

slope in xz plane is

$tan\theta = \frac{a_x}{g +a_z}$

$tan\theta = \frac{4}{9.81+0}$

$tan\theta =0.4077$

the maximum height of water surface at mid of inclination is

$\Delta h = \frac{d}{2} tan\theta$

$=\frac{0.4}{2}0.4077$

$\Delta h 0.082 cm$

the maximu height of wwater to avoid spilling is

$h_{max} = h_{tank} -\Delta h$

= 60 - 8.2

$h_{max} = 51.8 cm$

the height requird if no spill water is $h_{max} = 51.8 cm$

Answer:

Cloud computing services are going to be very important to supporting Ashville's mobile app since it has different uses. These applications uses include; data storage, as well as helping to provide network to any business data related work. This will improve the city of Ashville's mobile app operations considerably.

The benefits of using cloud computing are; it allows a business managers to be more concerned with running the business themselves rather than maintaining the data center. The use of cloud computing allows a company's IT administrators to focus on managing the company's operations, thereby allowing performance to be enhanced of the business enterprise.

A commercial company is able to create new technologies more rapidly with the use of cloud computing. Furthermore, the enterprise will be able to automate its activities using cloud computing. Cloud computing is also very important as it is more affordable and thus promotes the company's growth in the market. Cloud computing is also enhancing the global presence of the Ashville mobile app. The drawbacks of using cloud computing include the following; due to using the cloud infrastructure, the company's performance may be unreliable. People believe that cloud computing is not reliable and that cloud computing may not be secure at last and can't always be right for all workloads.

Use Excel, MatLab or a similar program to plot carrier thermal velocity as a function of temperature for both electrons and hole

Sidana [21]

Answer:

Solution 2:

The thermal energy of any particle is given as = $\frac{1}{2}mv^{2}$

where m= Effective mass of the particle,

v= Velocity of the particle

The average kinetic energy is given as = $\frac{3}{2}KT,$

where K= Boltzmann Constant

T= Temperautre of the particle

At equilibrium,

1/2 mv² = 3/2 KT

Hence, v= $\sqrt{\frac{3KT}{m}}$

As, effective mass ratio is calculated with respect to rest mass of electron,

melectron = 0.11 * 9.11 *10-31 kg

mhole = 0.35 *9.11 *10-31 kg

K = 1.38 × 10-23 m2 kg s-2 K-1

Plotting, over a range of temperature of 0 K to 400 K, we obtain the attached Graphs (attached).

Solution 3:

The above two curves plotted are not identical as seen. From the same value of Temperature, and under identical conditons, the Thermal velocity solely depends on effective mass ratio. And it is inversely proportional to effective mass ratio. More the effective mass ratio, less the thermal velocity and flatter the slope of the curve and vice versa. As, the mass ratio of holes is more than that of electrons, the curve of electrons has a steeper slope than that of holes. Hence, the curves are not just identical.
