Answer: The correct answer is "The wave will bend or defract".

Explanation:

Diffraction: It is the phenomenon in which the light gets bend around the corner of the aperture or a slit. There is a spreading of the waves as they pass through an aperture.

The wavelength of the wave is comparable or greater than the size of the aperture to observe diffraction. If the wavelength of the wave is not comparable or greater than the size of the aperture then in this case, the diffraction is unnoticeable.

In the given problem, a wave is approaching a barrier that has a small hole at the center. A small hole is aperture here. The wave will bend or defract. The diffraction phenomenon will occur in this case.

Therefore, the correct option is (B).

A chicken crosses a 7.50 m wide road at a constant speed of 0.367 m/s. How much time does it take to cross (in seconds)?
mars1129 [50]
<h3><u>Answer;</u></h3>

= 20.436 seconds

<h3><u>Explanation;</u></h3>

Speed = Distance × time

Therefore;

Time = Distance/speed

Distance = 7.50 m, speed = 0.367 m/s

Time = 7.50/0.367

         <u>= 20.436 seconds </u>

8. An airplane is flying at 200 m/s when it touches the ground at the airport. It has a constant negative acceleration, and slow
Temka [501]

Answer:

Explanation:

Given

Initial velocity u = 200m/s

Final velocity = 4m/s

Distance S = 4000m

Required

Acceleration

Substitute the given parameters into the formula

v² = u²+2as

4² = 200²+2a(4000)

16 = 40000+8000a

8000a = 16-40000

8000a = -39,984

a = - 39,984/8000

a = -4.998m/s²

Hence the acceleration is -4.998m/s²

chubhunter [2.5K]

Answer:

(1) Sure, the frequency is 1000 Hz.

Explanation:

Frequency = wave speed ÷ wave distance

wave speed = 100 m/s

wave distance = 10 cm = 10/100 = 0.1 m

Frequency = 100 ÷ 0.1 = 1000 Hz
