How is the energy harnessed and converted into useful energy?

Engineering
1 answer:
garri49 [273]2 years ago
6 0

Answer:

1. How energy is harnessed?  

Another way to tap solar energy is by collecting the sun's heat. Solar thermal power plants use heat from the sun to create steam, which can then be used to make electricity. On a smaller scale, solar panels that harness thermal energy can be used for heating water in homes, other buildings, and swimming pools.

2. How is solar energy converted into useful energy?

Solar panels convert the sun's light into usable solar energy using N-type and P-type semiconductor material. When sunlight is absorbed by these materials, the solar energy knocks electrons loose from their atoms, allowing the electrons to flow through the material to produce electricity.

Five batch jobs A through E arrive at a computer center in the order A to E at almost the same time. They have estimated running
Nikolay [14]

Answer:

Explanation:

The Turnaround time is the amount of time that elapses between the job arriving and completing. We assume that all jobs arrive at time 0, the turnaround time will simply be the time that they complete.

Round Robin:

we assume that the time quantum of the scheduler is 1 second.The table below gives a break down of which jobs will be processed during each time quantum. A asterisk(*) indicates that the job completes during that quantum.

1   2   3   4   5   6   7   8   9   10   11   12   13   14   15   16   17   18   19   20   21   22   23   24   25   26   27   28   29    30

A  B  C   D  E  A  B   C* D  E    A    B    D   E    A   B   D*   E     A   B     E     A    B* E   A     E  A    E*  A A

C* = 8

D*=17

B*=23

E*=28

AVERAGE TURNAROUND = (8+17+23+28+30)/5 =106/5 = 21.2 MINUTES

B) PRIORITY SCHEDULING:

1-6       7-14        15-24      25-26        27-30

   

 B           E             A             C            D

     AVERAGETURNAROUND =(6+14+24+26+30)/5 = 100/5 = 20 MINUTES.

C)FCFS

1-10      11-16      17-18      19-22      23-30

 

   A            B              C            D              E

   

AVERAGE TURNAROUND =(10+16+18+22+30)/5 = 96/5=19.2 MINTUES

D)SJF

1-2        3-6         7-12         13-20      21-30

C           D            B               E                A

AVERAGE TURNAROUND - (2+6+12+20+30)/5 =70/5 =14 MINUTES.

For a ceramic compound, what are the two characteristics of the component ions that determine the crystal structure?
DiKsa [7]

Answer:

The two characteristics of component ions that determine the crystal structure of a ceramic compound are:

1) The magnitude of electrical charge on each ion.

2) The relative sizes of both cations and anions.

Explanation:

Most ceramics normally contain both metallic and nonmetallic elements with ionic or covalent bonds. Thus, the structure of the metallic atoms, structure of the non-metallic atoms, and also the balance of charges produced by the valence electrons must be considered.

These ionic and covalent bonds i talked about earlier are the strong primary bonds that hold the atoms together and form the ceramic material. These chemical bonds are of two types:

i) they could either be ionic in character, meaning they involve a transfer of bonding electrons from electropositive atoms (cations) to electronegative atoms (anions),

ii) or they could be covalent in character, which involves orbital sharing of electrons between the constituent atoms or ions.

Thus, Covalent bonds are generally directional in nature, often dictating the types of crystal structure possible. Whereas, Ionic bonds, on the other hand, are entirely nondirectional. This nondirectional nature allows for hard-sphere packing arrangements of the ions into a variety of crystal structures.

So, we can deduce that;

The two characteristics of component ions that determine the crystal structure of a ceramic compound are:

1) The magnitude of electrical charge on each ion.

2) The relative sizes of both cations and anions.

A student checks her car's tyre air pressure at a petrol station and finds it is 31 psi. Re-express this as an absolute pressure
victus00 [196]

Answer:

Absolute Pressure=315.06256 kPa

Explanation:

Gauge pressure= 31 psi

Atmospheric Pressure at Sea level= 1 atm=101.325 kPa

1\ psi=6.89476\ kPa\\\Rightarrow 31\ psi=31\times 6.89476\\\Rightarrow 31\ psi=213.73756\ kPa=Gauge\ Pressure\\Absolute\ Pressure=Gauge\ Pressure+Atmospheric\ Pressure\\\Rightarrow Absolute\ Pressure=213.73756+101.325\\\therefore Absolute\ Pressure=315.06256\ kPa
