The piston engine uses the crankshaft to convert the reciprocating motion of the piston into rotary motion.

The crankshaft is used to convert reciprocating motion of the piston into rotary motion, while the conversion process is called torque, which is a twisting force. Aside from crankshaft, there are a total of four parts of the engine that work together in order to convert the reciprocating motion into rotary motion namely cylinder, or also called the chamber of the piston, the piston itself, and the connecting rod.

Write a statement that defines an ifstream object named inputFile and opens a file named "Friends.txt".

Simora [160]

Answer:

ifstream inputFile;

inputFile.open("Friends.txt");

Explanation:

Though, the programming language is not stated, questions like this are often from C++.

The first statement defines the ifstream object using the following syntax.

ifstream [object_name]

In this case, the object name is inputFile

So, the syntax becomes

ifstream inputFile;

The next line opens a file using the following syntax.

[object_name].open("Filename")

Here, object_name is inputFile and filename is Friends.txt

So, the open statement becomes

inputFile.open("Friends.txt")

An 8x16 font isstored in _________________ bytes. ? 8 ? 16 ? 4 ? 20

stiv31 [10]

Answer:

The answer to this question is 16 bytes.

Explanation:

8x16 font means it contains 16 rows by 8 columns of 1-bit pixel ( picture element ).

rows=16.

columns=8.

8 bit = 1 byte.

8x1 = 1 byte.

8x16 = 16 bytes.

So 8x16 font size requires 16 bytes of data to store a character.Hence we conclude that the answer is 16 bytes.

If a star system 30 parsecs distant is found to be broadcasting intelligent radio signals, then their news is already approximat

IrinaK [193]

Answer:

97.85 years, approximately.

Explanation:

Light travels at a constant speed of 186,000 mi/seg or 300,000km/seg accross the Universe (in vacuum conditions). Radio waves are also part of the electromagnetic spectrum, and they also travel at the same speed as Light does.

A light-year is a measure of the distance that Light travels during a year, that is, 5.88 trillion miles. Light travels the same distance per year because its speed is constant, and this is an excellent property that scientists take advantage to measure distances.

A parsec is 3.26 light-years (19 trillion miles), and (a very important datum to solve this question) one light-year is 0.306601 parsec, that is, in a year Light travels 0.306601 parsec at a constant speed. The same would happen with intelligent radio signals broadcasted from a distant star system.

So, considering all these facts, it is a matter of proportions to solve this question (mostly because speed of Light is constant):

$\frac{1 year}{0.306601 parsec} = \frac{X years}{30 parsecs}$

$x =\frac{1 year * 30 parsec}{0.306601 parsec}$

$x = \frac{30}{0.306601} years$

x = 97.84704 years or,

x = 97.85 years, approximately.

In other words, Light spends 97.85 years (terrestials) to travel 30 parsecs.

Likewise, radio waves travel at the same speed, so they spend the same years (97.85 years) travelling across the Universe to be finally detected by a radiotelescope located, for instance, here, in our planet.

Finally, the star system broadcasted intelligent radio signal with 'news' that are already approximately 97.85 years old'.
