Answer:
Explanation:
In order to answer this problem you have to know the depth of the column, we say R, this information is important because allows you to compute some harmonic of the tube. With this information you can compute the depth of the colum of air, by taking tino account that the new depth is R-L.
To find the fundamental mode you use:
n: mode of the sound
vs: sound speed
L: length of the column of air in the tube.
A) The fundamental mode id obtained for n=1:
B) For the 3rd harmonic you have:
C) For the 2nd harmonic:
Answer:
The new energy density is same as initial energy density u0 as it is independent of plate dimensions
Explanation:
As we know that energy density is total energy per unit volume
so we know that isolated plates of capacitor is placed here
here we have energy density given as
so we have
so it is independent of the dimensions of the plate while total charge on the plates is constant always
so energy density will not change and remains the same
Kinetic energy<span> is the </span>energy<span> of motion. An object that has motion - whether it is vertical or horizontal motion - has </span>kinetic energy<span>. It is expressed as:
KE = mv^2 /2
720 = 10.0v^2 /2
v = 12 m/s
Hope this answers the question. Have a nice day.</span>
Answer : The correct option is, (B) 
Explanation : Given,
Mass of proton = 
Speed of proton = 0.93 c
Formula used for relativistic momentum of the proton is:
where,
p = relativistic momentum of the proton
= mass of proton
v = speed of proton
c = speed of light = 
Now put all the given values in the above formula, we get:
Therefore, the relativistic momentum of the proton is,
Explanation:
The five-step process for treating a muscle or joint injury such as an ankle sprain is called "P.R.I.C.E." which is short for Protection, Rest, Ice, Compression, and Elevation).
