Answer:
The basic difference between Total cost and total revenue is that the total cost includes the total expenditure incurred on the production of a commodity whereas total revenue refers to the money received from selling that commodity.
Explanation:
Answer:
Some of the demerits or disadvantages of using a very slow castings rates in production of metal by the method of casting includes, with the solidification of metal, it may begin even before the mold is filled fully, which may result in defects such as shrinkage.
Secondly, the rate of slow casting will create castings that have a grain coarse structure that will affect the strength of the castings.
Explanation:
Solution
The disadvantageous of slow casting rates in the production of metals by casting method is explained below:
(1) The solidification of metal may start even before the mold is filled completely, which may create or produce defects such as mis-runs and shrinkage and shrinkage cavity.
So, the slow cavity rate will produce partial and incomplete castings
(2) Slow casting rate will produce castings which have a coarse grain structure which therefore affects the strength of the castings adversely.

NASA scientists have determined that the chance a single person would get hit by a piece of falling satellite is one in 3,200. What can you infer based on this probability?
A. Satellites that enter Earth’s atmosphere land mostly in the ocean.
B. NASA does a good job informing people of when satellites will enter the atmosphere.
C. Satellites that enter Earth’s atmosphere land mostly in unpopulated areas.
D. Much of a satellite is destroyed during the process of entering Earth’s atmosphere.
A effective ground-fault current path is an intentionally constructed, low-impedance electrically conductive path designed and intended to carry current during ground-fault conditions from the point of grounding on a wiring system to the electrical supply source.
<h3>Is earth an effective ground fault current path?</h3>
- Sticking the wire in the ground is not sufficient since the earth is not thought to be a reliable ground-fault current channel.
- The electrical system of a building or other structure is based on grounding.
- To give a fault current a secure path to travel, grounding is used.
- When installing switches, light fixtures, appliances, and receptacles, a complete ground route must be kept.
- The undesired current flow trips circuit breakers or blows fuses in a system that is correctly grounded.
- Through the use of a grounding bank, effective grounding maintains voltages within predetermined limits during a line-to-ground fault (short-circuit condition).
