Answer:
e. 400 Hz
Explanation:
In closed organ pipe, only odd harmonics of fundamental note is possible .
The fundamental frequency is 200 Hz . Then other overtones will be having following frequencies .
200 x 3 , 200 x 5 , 200 x 7 , 200 x 9 etc
600 Hz , 1000 Hz , 1400 Hz , 1800 Hz .
Frequency not possible is 400 Hz .

DETAILS IN THE QUESTION INSUFFICIENT TO ANSWER
Explanation:
Assuming the liquid to be water ,
the density 
of water is : 
Buoyant force exerted by a liquid on an object with 
of it's volume immersed is :
where ,
is the buoyant force
is the density of the liquid
is the acceleration due to gravity
Thus at equilibrium:
from these , we get the density of brass to be 
which is not possible
Answer:
20 m/s/s
Explanation:
F=ma, 350=17.5 * a, a=20 m/s/s
Infared = used by police
gamma = short wavelength
radio = largest wavelength
visible = only ones we can see
An atom would be your answer, so B!
