True or False? The superposition or overlapping of two waves always results in destructive interference between the different wa

ves.
Physics

8 0

Answer:

Explanation:

False

When two waves overlap or superimpose over each other then they either undergo Constructive or destructive interference.

waves are the disturbance created by a force and add up to gives constructive interference when they are in the same line i.e. in the same phase.

When these disturbances are in the opposite phase then they superimpose to give destructive interference where the amplitude of the resulting wave will be much smaller as compared to original waves.

The surface charge density on an infinite charged plane is −1.70 x 10^−6 C/m^2 . A proton is shot straight away from the plane a
goldfiish [28.3K]

Answer:

Acceleration of proton will be -9.197\times 10^{12}m/sec^2

Explanation:

We have given surface charge density of an infinite charged plate \sigma = -1.70\times 10^{-6}C/m^2

Electric field due to infinite sheet charge is given by E=\frac{\sigma }{2\epsilon _0}=\frac{-1.7\times 10^{-6}}{2\times 8.85\times10^{-12}}=-0.096\times 10^6=-9.6\times 10^4N/C

Charge in proton is given by e=1.6\times 10^{-19}C

So force on proton F=qE=1.6\times 10^{-19}\times -9.6\times 10^4=-15.36\times 10^{-15}N

Mass of proton m=1.67\times 10^{-27}kg

According to newtons second law force F = mass × acceleration

So -15.36\times10^{-15}=1.67\times 10^{-27}a

a=-9.197\times 10^{12}m/sec^2

The divisions of the nervous system that have antagonistic is called
Mashutka [201]

Answer:

the sympathetic division and the parasympathetic division.

Explanation:

These two divisions have antagonistic (opposing) effects on the internal organs they innervate (send nerves to = act on).

hope this helps :)

Charge is distributed uniformly throughout the volume of an infinitely long solid Cylinder of radius R what is the electric fiel
Arada [10]

Solution :

Let us consider the Gaussian surface that is in the form of a cylinder having a radius of r and a length of A which is $\text{coaxial with the charged cylinder}$.

The charged enclosed by the cylinder is given by,

$q=\rho V$       (here, V = $\pi r^2l$  is the volume of the cylinder)

  $=\pi r^2lp$    

If $\rho$ is positive, then the electric field lines moves in the radial outward direction and is normal to Gaussian surface which is distributed uniformly.

Therefore, total flux through Gaussian cylinder is :

$\phi=EA_{cyl}$

   $=E(2\pi rl)$

Now using Gauss' law, we get

$2\pi \epsilon_0rlE = \pi r^2lp$

or $E=\frac{\rho r}{2 \epsilon_0}$

Therefore, the electric field is $E=\frac{\rho r}{2 \epsilon_0}$

Hence, option (d) is correct.
