Explanation:
In this case, when the collar mass is released, it will move from the rest point, to a point between A and B and then to point C. While it approaches point C, the amount of stretch will decrease and the spring force will reduce.At point C, the spring reaches its maximum stretch, leaving un-stretched length of spring l, making point C the position where the velocity of the collar is maximum.The energy possessed due to motion of the collar is kinetic energy, thus the magnitude of the velocity can be calculated from;
Kinetic energy, K.E = 1/2*m*v²
Thus
where m is mass of collar and v is speed of collar. The faster the collar the more the kinetic energy.

Answer:
1/2
Explanation:
Lets take N is the speed of engine in RPM.
As we know that in two stroke engine ,crank rotates one times in two stroke of piston.Every rotation of crank gives one power stroke.It means that two stroke give one power stroke.
On the other hand in four stroke engine,crank rotates two times in 4 stroke of piston.It means that 4 stroke of piston gives one power stoke .
So we can say that the ratio of number of power stroke in two stroke engine to the number of power stroke in four stroke engine is 1/2.
Answer:
D. A and B
Explanation:
1. The method Console.Write() is an overloaded method in a language like C#.
One of its variations could be as follows;
<em>Console.Write(String format, Object a, Object b).</em>
This contains three parameters and will write the text representation of the specified objects to the standard output stream using the information specified by the format specifier. Parameter 1 is <em>format</em> which is a composite format string representing the format specifier. Parameter 2 is <em>a</em>, which is the first object to be written using <em>format. </em>Parameter 3 is b, which is the second object to be written using <em>format</em>.
2. The method Console.WriteLine() has the same characteristics as Console.Write() above, except that it writes the text representation of the specified objects, followed by current line terminator then to the standard output stream using the information specified by the format specifier.
3. Console.WriteFormat() does not exist, at least not in C# or .NET
Therefore, Console.Write() and Console.WriteLine() have the capacity to display formatted data.

Answer:
It wouldn't get any louder then maybe 3db more
Explanation:
There's even a equation if you wanted to check this out but, if they are the same generator same model and all and made the same precise noise it wouldn't increase more then 3db.
