Answer:
The image to the left (with the disks on it)
Explanation:
Interference in any type of wave can be gotten in two forms, constructive interference, and destructive interference.
The constructive interference is between two waves with the same phase, that is, each crest and trough correspond with the crest and trough of the another getting as result a wave with twice the amplitude of the original one.
The destructive interference is between two waves out of phase, in which the crest of one cancels with the trough of another.
If light passes for a slit it will get a diffraction pattern in a screen, at which each bright pattern corresponds to a crest and a dark pattern to a trough, as a consequence of constructive interference and destructive interference in different points of its propagation to the screen.
The circular shape of the disks can be a representation of the wavefront and how the overlaps make constructive and destructive interference in order to get the diffraction pattern.
Answer:
a) 20.29N
b) 19.43N
c) 15N
Explanation:
To find the magnitude of the resultant vectors you first calculate the components of the vector for the angle in between them, next, you sum the x and y component, and finally, you calculate the magnitude.
In all these calculations you can asume that one of the vectors coincides with the x-axis.
a)
b)
c)
The chemical reaction causes electricity to flow through the terminals to the load attached. Some of the acid in the battery remains on the plates as it flows through. When the battery is recharged the acid is returned to the liquid solution to provide more power later.
Answer:
The magnitude of the average emf induced in the coil is approximately o.32 V.
Explanation:
As, no. of loops = N = 10
Area = 0.23 m^2
Magnetic field = B = 0.047 T
Δt = 0.34 s
These are the given things now we have to find the EMF. So the formula of emf is:
emf = e = N×ΔФ/Δt
Therefore, ΔФ = B . ΔA = BΔAcos(θ)
Since, flux is maximum so θ = 0 and cos(0) = 1
Then,
ΔФ = BA
e = N×(BΔA)/Δt
e = 10×(0.047×0.23)/0.34
e = 0.317 V.
So, we can write it by rounding off the digit
e ≅ 0.32 V.
There are 6 types of quarks.
