For the majority of instruments f = n f0 where f is the resonating frequency, n is any whole number and f0 is the fundamental.
<span>This applies to trumpets, violins, flutes and a broad range. </span>
<span>In such a </span>case<span> the first harmonic would be at n=1 and the second harmonic would be at n=2 </span>
<span>which gives a frequency of 84 Hz</span>
Given:
Force(F): 100 N
Acceleration: 10 m/s^2
Now we know that
F= mx a
Where F is the force acting on the object which is measured in Newton
m is the mass of the object measured in Kg
a is the acceleration measured in m/s^2
Substituting the given values in the above formula we get
100= 10m
m= 10 Kg
The answer is c and my reason is I have straight As
Answer:

Explanation:
Given:
- Initial temperature,

- initial volume,

- final temperature,

- volumetric coefficient of thermal expansion for gasoline,

- volumetric coefficient of thermal expansion for steel,

<u>Now the increment in the volume of the container:</u>



<u>and the increment in the volume of the gasoline:</u>



<u>Hence the difference in the increment of the two volumes:</u>


of the gasoline spills out of the container in this case.
