What can accurately be said about a resultant wave that displays both reinforcement and interference?        A. Molecules remain

in their normal positions at spots of reinforcement.   B. Maximum interference occurs where the troughs of the two component waves are in phase.   C. The crests of the two component waves are in phase where interference occurs in the resultant wave.   D. The component waves have different frequencies.

Answer;

D. The component waves have different frequencies.

Explanation;

-Interference is a property of waves that results from combination of two or more wave trains moving on intersecting or coincident paths. This effect results to the addition of the amplitudes of the individual waves at each point affected by more than one wave.

-When two waves are of the same frequency and are in phase (which means; they vibrate at the same rate and are maximum at the same time), the wave amplitudes are reinforced, producing constructive interference.

-Conversely, when two waves are out of phase by half period (meaning that one is minimum when the other is maximum), the result is destructive interference, producing complete annulment if they are of equal amplitude.

The diagram below shows the velocity vectors for two cars that are moving relative to each other.
scoundrel [369]

Answer:

The answer is "5 \ \frac{m}{s} \ west"

Explanation:

\to \vec{V_1} = (25 \frac{m}{s}) (\hat{-i})\\\\\to  \vec{V_2} = (20 \frac{m}{s}) (\hat{-i})\\\\

velocity of car | respect to car :

\to \vec{V_{12}} = \vec{V_1} - \vec{V_2}\\\\

          =\vec{-25} \hat{i}+ \vec{20} \hat{i}\\\\= 5 \ \frac{m}{s} \ west

Can someone help with these
yaroslaw [1]

<em><u>One</u></em>

Givens

  • delta B = 0.20 T/s
  • A = 0.07 m^2
  • R = 3.5 ohms

Formula

Φ = ΔB*A

e = Φ

Solution (first part)

e = 0.2 * 0.07

e = 0.014 emf

Solution (second part)

i = e/R

i = 0.014 / 3.5

i = 4 * 10^-3

i = 4 ma

Answer

A

<em><u>Two</u></em>

Givens

N = 200 turns

Φ = 30 degrees

Delta B = 0.45 T/s

phi = 30 degrees

r = 0.06 meters

Formula

e = -N * delta B * A * Cos(phi)

Solution

e = -200 * 0.45 (pi r^2) * Cos(30)

e = - 200 * 0.45 * (3.14 * 0.06^2) * cos(30)

e = 0.881 emf

Answer

A
