Answer:
Lowest resonant frequency:
Wave Speed:
Explanation:
The lowest resonant frequency
For a fixed string a resonant mode is always a integer multiple of fundamental frequency (the lowest resonant frequency):
Is the frequency for a resonant mode
is fundamental frequency (the lowest resonant frequency).
Due to problem says that there's not intermediate resonant frequencies between 684 Hz and 798 Hz, i.e, they are consecutive resonant modes, equations are as follows:
Solving for n from equation (1) and replacing it in the equation (2)
And finally solving for
Wave speed
For a fixed string the wave speed can be calculated by using
Where V is the wave speed and L is the string length.
So, using this equation and solving for V:
<em>It Is very important convert the string length unit to meters</em>
When water evaporates of your body it cools you down, hence why after a shower when the water droplets begin to evaporate you feel cold
They maintain the same distance between each other throughout the fall
Answer:
Correct answer:
As the temperature increases, the kinetic energy of the molecules increases.
Explanation:
The relation between kinetic energy and temperature in an ideal gas which we will take as an example is given by the following formula:
Ek = 3/2 N k T ,
where N is the total number of molecules a k is a Boltzmann constant.
If we assume that the total number of molecules is a constant, kinetic energy only depends on temperature.

Speed is the time rate of an object moving from one place to another, while velocity is the rate and direction of the object's movement. They are very similar but they don't mean the same thing.
