Answer: See explanation
Explanation:
69.48 / 7.2 = 965 as written in the question isn't correct. The correct answer should have been:
69.48 / 7.2 = 9.65
It should be noted that when we divide, the answer that one gets cannot be more than the two numbers that were used for the division. Hence, there's no way that 965 would be more than 69.48 and 7.2.
1. Why is the perfect elastic-plastic model adopted in steel design?
Answer:
Explained below
Explanation:
Perfect Elastic Plastic in steel design is simply a method whereby the structural members are selected using the criteria of the overall ultimate capacity of the system. However, when safety is considered, the applied loads are usually increased by factors of safety as prescribed in the relevant steel design codes. Therefore, this model of design is just based on the yield capacity of the steel.

Your Answer would be A I believe.
Technician A says that a component may be grounded through its mounting to a major metal part. Technician B says that some components must be grounded by connecting its positive terminal to a metal frame
Answer:
Technician B is correct
Explanation:
Grounding of component can be done by either connecting its positive terminal to a metal frame and then connecting its negative wire to the ground and not by mounting it on a major metal part hence Technician B is correct while Technician B is incorrect .
Electrical grounding is an alternate route created to allow excess current entering an equipment to go the ground without destroying the component
An individual is planning to take an 800-mile trip between two large cities. Three pos-sibilities exist: air, rail, or auto. The person is willing to pay $25 for every hour savedin making the trip. The trip by air costs $600 and travel time is 8 hours, by rail the costis $450 and travel time is 16 hours, and by auto the cost is $200 and travel time is 20 hours.
(a) Which mode is the best choice?
(b) What factors other than cost might influence the decision regarding which mode to use?
Answer:
1. Auto is the best mode since it is the cheapest
2. Safety, reliability, convenience should be considered
Explanation:
1.
This person is willing to pay $25 per hour.
To get the mode, which is the best choice I used this formula
Cost of trip + 25T
T = time or number of hours
By air travel
Cost = $600, T = 8 hours
600+25(8)
= 600+200
= 800 dollars
By rail,
Cost = $450
T = 16 hours
450+25(16)
= 450+400
= 850 dollars
By auto,
Cost = $200
T = 20 hours
200+25(20)
= 200+500
= 700 dollars
From these calculations the cost of Traveling by auto is the cheapest so it is the best mode.
2. Other factors to consider when choosing an alternative mode of transport
A. Safety: this transportation material should be able to get to it's destination without any form of damages happening
B. Reliability: the material should be able to fulfill it's requirements
C. Convenience: in terms of availability per day and also the frequency of traveling time
A chemist mixed two substances together: a colorless liquid with a strong smell and a white solid with no smell. The substances' repeating groups of atoms are shown above on the left. After they were mixed, the chemist analyzed the results and found two substances. One ending substance had the repeating group of atoms shown above on the right. Is the ending substance the same substance as the colorless liquid? What happened to the atoms of the starting substances when the ending substances formed? Be sure to explain your answers to both of these questions.
Answer:
[a]. It is the same substance as the colorless liquid with a strong smell.
[b]. the substance with colorless liquid with a strong smell and a white solid with no smell are being used up to produce the ending substance had the repeating group of atoms shown above on the right and the other ending substance.
Explanation:
Atoms are referred to be the smallest units of a substance although it can be sub-divided into smaller units such as proton, neutron and electron. When atoms combines in group they form a molecule.
From the question above it is seen that two substances were mixed together to give two ending substances that is:
substance A [ colorless liquid with a strong smell] + substance B[white solid with no smell] ---------> substance C[ repeating group of atoms shown above on the right] + substance D.
The ending substance that is, substance C is the same substance as substance A which is the colorless liquid with a strong smell.
When the substance A reacted with substance B, it gives substance C and D that is the ending substances are the products of the reaction between A and B.
Hence, the substance with colorless liquid with a strong smell and a white solid with no smell are being used up to produce the ending substance had the repeating group of atoms shown above on the right and the other ending substance.
