The work practice should be followed to best prevent the ingestion of chemicals is "Do not eat or drink in regulated areas".

Eating or drinking in regulated areas are unsafe as people may accidently take in chemicals through their mouth.

Furthermore, in order to avoid the ingestion of chemicals, people should wash their hands immediately they are done using chemicals.

Lastly, pipetting should not be carried out through the use of mouth.

Incremental software development could be very effectively used for customers who do not have a clear idea about the systems nee
avanturin [10]

<u>Software Development and Client Needs</u>

In Incremental method of software development customers who do not have a basic idea of the development process are being carried along on like other methods that will relegate them to the background until a product is ready.

With this model and structure in place, when softwares/ products are built from several stages e.g prototype, testing, and when new features are added customers are always carried along with their valuable feedback and suggested greatly considered to achieve the customers satisfactions

This model will work well for the customers/clients who does not have a clear idea on the systems needed for their operations.

In summary the incremental model combines features from the waterfall and prototyping model.

A satellite is launched 600 km from the surface of the earth, with an initial velocity of 8333.3 m./s, acting parallel to the ta
Vikki [24]

Answer:

eccentrcity of orbit is 0.22

Explanation:

GIVEN DATA:

Initial velocity of satellite = 8333.3 m/s

distance from the sun is 600 km

radius of earth is 6378 km

as satellite is acting parallel to the earth therefore\theta angle = 0

and radial component of given velocity is zero

we haveh = r_o v_r_o = 6378+600 =6.97*10^6 m

h = 6.97*10^6 *8333.3 = 58.08*10^9 m^2/s

we know that

\frac{1}{r} =\frac{GM}{h^2} \times ( i + \epsilon cos\theta)

GM = gr^2 = 9.81*(6.37*10^6)^2 = 398*10^{12} m^3/s

so

\frac{1}{6.97*10^6} =\frac{398*10^{12}}{(58.08*10^9)^2} \times ( i + \epsilon cos0)

solvingt for \epsilon)

\epsilon = 0.22)

therefore eccentrcity of orbit is 0.22

You are driving on a roadway with multiple lanes of travel in the same direction, and are approaching an emergency vehicle parke
solmaris [256]

Answer: a. Leave the lane closest to the emergency as soon as it is safe to do so, or slow down to a speed of 20 MPH below the posted speed limit.

Explanation:

Giving a way to the law enforcement vehicle and a medical emergency vehicle is necessary. If one approaches an emergency vehicle parked along the roadway one should change the lane as the vehicle may not move and the driver may also waste his or her time also one should also slow down his or her speed while approaching the vehicle as most of the emergency vehicle are in rush to reach the hospital so the driver should maintain some distance with the medical emergency vehicle.

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.
