Answer:
The amplitude of the resultant wave will be 0.
Explanation:
Suppose the first wave has an amplitude of A. Its angle is given as wt.
The second way will also have the same amplitude as that of first.
After the reflection, a phase shift of π is added So the wave is given as
Adding the two waves give
So the amplitude of the resultant wave will be 0.
<span>When two electrical charges, of opposite sign and equal
magnitude, are separated by a distance, a dipole is established. The size of a
dipole is measured by its dipole moment</span><span> . Dip</span>ole moment is measured in Debye units, which is equal to the
distance between the charges multiplied by the charge
<span>Dipolemoment 'D' = e x d
where e= charge and d= distance by which charge is separated. </span><span>
In this case e = charge on electron = 1.6 x10^-19 C</span>
D = 1.6 x10^-19 C (
1x10^-10 m) =1.6x10^-29 Cm
Hydrogen .When acids touches all metal hydrogen gas is emitted .Strong acids is one that can produce a high concentration of hydrogen ions.Hope this helped!
The effective acceleration or deceleration due to gravity depends on the inclined angle of the track relative to ground; the steeper the slope is the greater the effective acceleration.
You should solve this like you would any algebraic expression. Divide both sides by acceleration (a) and you will isolate the mass (m) to one side. Now divide the force (f) by acceleration (a).
F/a=m
