Answer:
[tex]K=2J-R[/tex]
Explanation:
Let [tex]R[/tex] denotes the number of sides of a triangle.
Let [tex]J[/tex] denotes the number of joints.
Let [tex]M[/tex] denotes the number of members.
Let [tex]K[/tex] denotes the unknown to be solved.
Now write the structural stability formula:
[tex]K=2J-R[/tex]
Here, design is stable if [tex]M=K[/tex]
Design is unstable if [tex]M<K[/tex]
Design is indeterminate if [tex]M>K[/tex]

The first inventors of the light bulb, Henry Woodward and Mathew Evans, faced which of the following problems?
The device was not very long lasting
The gas used in the light bulb was polsonous
The patent they tried to file for their invention was not accepted.
The nitrogen gas caused the light bulb to explode,
Answer:
The device was not very long lasting
Explanation:
Henry Woodward and Mathew Evans were two British scientist who invented first light bulb in 1860.
The challenge they faced while inventing light bulb was the log lasting light filament. Earlier filament was made up of carbonized paper which was not long lasting and has light for very less time period. Later they solve it by making carbon fiber filament derived from cotton and got patent for the same invention. But then because of financial issues they sold their patent to Edison.
Hence, the correct answer is "The device was not very long lasting".

Combining two strings is called
Answer:
The appropriate response is "Concatenation". A further explanation is given below.
Explanation:
Two or much more strings are almost always concatenated besides space-saving purposes, and therefore could be acknowledged as either a single product. A straightforward example that demonstrates concatenation should be to figure out what it means. How and why that ends up making a term separate from several other phrases is that almost all the messages are stacked together without any open space between each one.Describe carbonation as it applies to the four-stroke engine.

What is a combination circuit? A combination circuit:
Answer:
Combination circuit; The basic strategy for the analysis of combination circuits involves using the meaning of equivalent resistance for parallel branches to transform the combination circuit into a series circuit.
Example:
The use of both series and parallel connections within the same circuit. In this case, light bulbs A and B are connected by parallel connections and light bulbs C and D are connected by series connections. This is an example of a combination circuit.

Can somebody help me?? “ what is the approximate frequency of this signal in this time window ?
Answer:
The approximate frequency of the signal is 12 Hertz
Explanation:
Frequency is defined as the number of complete cycles that passes a given point in a given time
One cycle is the motion that describes one complete rotation, such that one cycle is described by the region between successive crest or peaks
Therefore, we have from the diagram;
The number of cycles in 0.75 seconds ≈ 9 cycles
The number of cycles expected to pass in one second = 9 cycles/(0.75 seconds) = 12 cycles/second = 12 Hertz
The approximate frequency of the signal, f = 12 cycles/second = 12 Hertz.

1. How is high-speed internet typically transmitted around the world? over telephone wires b. through fiber optic cables c. beamed wirelessly to homes d via satellites
Answer:
High speed internet is typically transmitted around the world;
b. Through fiber optic cables
Explanation:
High speed internet is typically transmitted through fiber optic cables such as the Submarine Cables that makes connection through two cables that connects USA to Europe over the Atlantic Ocean, and the Middle East to Europe Terrestrial Cable Systems (MEETS) which is a cable network of 1,400 km and is being built to have an initial capacity of 200 Gbps
Other example of fiber optic cable assisted internet broadband transmission are the Diverse Route for European and Asian Markets (DREAM) terrestrial cable that connects Germany, Kazakhstan, Russia, and China, TEA NEXT that provides connection between borders on the East and West of Russia and Euro-Russia-Mongolia-China (ERMC) terrestrial cable
High-speed internet typically transmitted around the world through the use
of fiber optic cables.
Fiber optic cablesThese are connections which help transmit internet from one place to
another. It is a very fast method with a very low lag time. This is why it's used
for high speed internet transmission.
These cables are also able to withstand high traffic while other forms can't
do it thereby making option B the most appropriate.
