displacement of the plane is given as
time taken by the plane
now the velocity is given as
so the velocity of airplane is 399 mi/h towards South West
I think it #3(not Sure) I think Its because of their long wavelengths that tsunamis behave as shallow-water waves.
Answer:
c. absorbs all the energy that strikes it.
Explanation:
<em>An ideal black body is an object that absorbs every light energy (irrespective of the wavelength and direction) that strikes it without reflecting any in return. </em>
<em>Such objects or bodies usually appear perfectly black and will only emit radiation when heated to a very high temperature.</em>
Answer:
Option D
2 m/s
Explanation:
The speed is given by distance/time
The complete wave has a distance of 8 m (This is the wavelength)
Time taken for complete wave is 4 s
Therefore, velocity= 8 m/ 4 s= 2 m/s
The amplitude is the distance between crest and trough hence 9 m- 6 m= 3 m
Frequency is 1/period and in this case period is 4 s hence frequency= 1/4= 0.25 Hz
Essentially, what we wanted is velocity
52,200m/min bro. Hope this is the right answer
