We have the equation for electric field E = kQ/
Where k is a constant, Q is the charge of source and d is the distance from center.
In this case E is inversely proportional to
So,
= 485 N/C
= 0.208 cm
= 0.620 cm
= ?
=
= 53.20 N/C
Answer:
0.0443 m/s
Explanation:
= Mass of honeybee = 0.15 g
= Mass of popsicle stick = 4.75 g
= Velocity of honeybee
= Velocity of stick = 0.14 cm/s
In this system the linear momentum is conserved
The velocity of the bee is 4.43 cm/s or 0.0443 m/s
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:
