For automobile engines, identify the best choice of motor oil.

Engineering
1 answer:
Vlad1618 [11]3 years ago
6 0

Answer:

C. Low viscosity for Maine in the winter and high viscosity for Florida in the summer.

Explanation:

The choice of motor oil or engine oil depends on the type of engine and also on the type of climate on which the engine runs.

In winter climates, we should use oil with low viscosity as at lower temperatures, the it flows more readily if its viscosity is low.

But the summer season needs a relatively thicker oil so as to reduce the thinning effect of the oil out of the engine.

Thus for Maine in the winter season, we need a low viscosity oil and for Florida a high viscosity oil in the summer season.

Therefore, option (c) is correct.

If you were to plot the voltage versus the current for a given circuit, what would you expect the slope of the line to be? If no
Brut [27]

Answer:

Part 1: It would be a straight line, current will be directly proportional to the voltage.

Part 2: The current would taper off and will have negligible increase after the voltage  reaches a certain  value. Graph attached.

Explanation:

For the first part, voltage and current have a linear relationship as dictated by the Ohm's law.

V=I*R

where V is the voltage, I is the current, and R is the resistance. As the Voltage increase, current is bound to increase too, given that the resistance remains constant.

In the second part, resistance is not constant. As an element heats up, it consumes more current because the free sea of electrons inside are moving more rapidly, disrupting the flow of charge. So, as the voltage increase, the current does increase, but so does the resistance. Leaving less room for the current to increase. This rise in temperature is shown in the graph attached, as current tapers.

Which of the following is true Select one: a. HTML stands for Hyper Text Markup Language is a language for describing web pages
Free_Kalibri [48]

Answer:

The answer to the above question is option C (HTML stands for Hyper Text Markup Language is a language for describing web pages and not a programming language).

Explanation:

HTML stands for Hypertext Markup Language.

HTML  is a web language that allows users to create and structure sections, paragraphs, headings, links, and block quotes to define the structure of web pages by using various tags.

HTML describes the structure of a web page semantically and HTML elements are the building blocks of HTML pages.

HTML runs natively in every web browser. When working with HTML, simple code structures (tags and attributes) are used to mark up a website page. To identify HTML documents, they are files that end with a .html or .htm extension.

HTML is not a programming language, because it doesn't have the ability to be used as functional purposes, it can only be used for structural purposes. HTML only contains a set of rules for encoding documents in a format that is both human and machine readable.

HTML is also not a sequential programming language (Sequential languages are languages that were designed for writing sequential programs), as one cannot encode logical instructions to a computer processor using HTML.

You are the curator of a museum. The museum is running short of funds, so you decide to increase revenue. Should you increase or
blondinia [14]

Answer:

Explanation:

If the museum is running short of funds, and you decide to increase revenue. An increase or decrease in the price of admission into the museum depends on the following:

1. If demand for admission into the museum is elastic there are two possible outcomes

a. An increase in the price of admission leads to a decrease in the quantity demand of admission into the museum

b. A decrease in price of admission into the museum leads to an increase in the quantity demand of admission into the museum.

This follows the law of demand which states that "the higher the price, the lower the quantity demanded and the lower the price, the higher the quantity demanded".

2. If the demand for admission into the museum is inelastic, then an increase in price will lead to an increase in revenue of the museum.

Therefore, before the curator increase the price of admission into the museum, he should first determine the price elasticity of demand of the museum.
