We are given an electromagnetic wave with a frequency of 5.09 x 10^14 Hz and travelling through a transparent medium. If the medium was vacuum, the speed of the wave would be equal to the speed of light. Otherwise, the main factor that would determine the speed of the wave is its wavelength.
let the plane is flying at some angle theta with west towards north
Now we can use the components
now since plane has to fly towards west so net speed in north must be equal to speed in south for air
So we can say
so plane has to fly in direction 14.5 degree North of west
C good luck ok good luck with
Answer: Transverse wave
Explanation:
This type of wave is transverse wave. Transverse wave is a wave that occurs when the vibration of the medium is perpendicular to the direction of the wave. According to the question, the crowd were standing vertically but they were arranged in the stadium in the horizontal manner.
Answer:
0.02325 m^3
Explanation:
P1 = 100000Pa , v1 = 0.0279m^3
P2= 120000Pa . V2 = ?
as mass and temperature are constant using ratio method for Boyle'slaw
P2V2= P1V1
or V2= P1V1/P2
V2 = 100000×0.0279/120000
V2= 0.02325 m^3
