Answer:
It is possible because, the TV broadcast audio and video signals in radio frequency which travels at the speed of light while the audio signals travel to those present in the stadium at the speed of sound which is over eight hundred thousand times slower than the speed of light
Explanation:
It is possible because of the following;
1. TV signals from the camera (including the captured sound) very close to the field of play are transmitted through the radio frequency bands and as such are a form of electromagnetic radiation that travels at the speed of light which is about 300,000 km/second
It will therefore, take 1 second for a sound of the game to reach someone located at 300,000,000 meters watching a live televised game
2. The speed of sound is about 343 m/second and it therefore takes up to 2 seconds for a sound to reach someone 686 meters away from the ball in the stadium.
Answer: The final mass of the tank is 2.46kg
Explanation: All shown in the attachment.
Assumptions:
i. Argon is treated as an ideal gas at the specified conditions.
ii. Isentropic relation of ideal gas applies at the given conditions.
Answer:0.3meters
Explanation:
wavelength=velocity ➗ frequency
wavelength=300.80 ➗ 1030.80
Wavelength=0.3m
Answer:
198.2m/s
Explanation:
Speed of a wave(v) is the product of the frequency of the wave (f) and its wavelength(¶).
Mathematically, v = f/¶
Given frequency of the middle C = 261.63Hz
Wavelength = 131.87cm
Converting this to meters we have;
131.87/100 = 1.32m
Speed of the sound = 261.63/1.32
Speed of the sound = 198.20m/s
Therefore the speed of sound for middle C is 198.2m/s
It’s the first one 28282929/9292
