Now consider a wave which is paired with seven other waves into seven pairs. The two waves in each pairing are identical, except

that one of them is shifted relative to the other in the pair by the distance shown:A. -(1/2) ?B. 2?C. -5?D. (3/2)?E. 0F. (17/2)?G. (6/2)?Identify which of the seven pairs will interfere constructively and which will interfere destructively. Each letter represents a pair of waves.Enter the letters of the pairs that correspond to constructive interference in alphabetical order and the letters of the pairs that correspond to pairs that interfere destructively in alphabetical order separated by a comma. For example if pairs A, B and D interfere constructively and pairs C and F interfere destructively enter ABD,CF.

Answer:

<em>BCEG,ADF</em>

Explanation:

Between 2 waves, if path difference is mλ, m is an integer and they interfere constructively.

Between 2 waves, if path difference is (m+1/2)λ, m is an integer and they interfere destructively.

<em>BCEG,ADF</em>

To solve this problem, it is necessary to apply the concepts related to speed of light and the kinematic equations of speed description.

The speed by definition can be expressed as the path of a particle during a certain time, in our case,

v = \frac{d}{t}

Where,

d= distance

v = speed

c = Speed of light (3*10^8m/s)

Replacing to find the time we have,

t=\frac{d}{v}

t = \frac{47000}{0.99542*(c)}

t = \frac{47000}{0.99542*(3*10^8)}

t = 1.57*10^{-4}s

Therefore the time is 1.57*10^{-4}s

A customer sits in an amusement park ride in which the compartment is to be pulled downwards in the negative direction of y axis

This movement of the coin relative to the knee is not under an inertial frame, because knee is accelerated relative to the coin.

a) coin acceleration relative to the ground: g = 9.81 m/s^2. This is the acceleration due to the atraction of the earth, given that the coin is not tied to the car or to the knee.

b) coin acceleration relative to the knee: acceleration of the coin relative to the ground - acceleration of the knee relative to the ground = - g - (-1.24g) = 0.24 g = 0.24 * 9.81 m^2^2 = 2.354 m/s^2

c) time to the coin move 2.2 m upward, relative to the car

d =  a*t^2 / 2 , where a is the acceleration relative to the car (same of the knee)

=> t = √(2d/a) = √(2*2.2m/2.354 m/s^2) = 1.37 s

d) actual force on the coin

Use the acceleration relative to the ground, a=g = 9.81 m/s^2

F = m*a = 0.567 g * 10^-3 kg/g * 9.81 m/s^2 = 5.56*10^-3 N


e) apparent force

Use apparent acceleration, a = 2.354 m/s^2

F = m*a = 0.567*10^-3 kg * 2.354 m/s^2 = 1.33*10^-3 N
